Is there a good way to use JavaScript to send a form submission, but get
back the response as a string, rather than loading it into a page? I
could write the code to send the submission via XMLHttpRequest, but that
seems hard... especially implementing multipart-encoded form submission
such as required for file upload.
I have email, password and some other fields, and I'm using $.post to send data for Ajax submission.
The problem is that I don't want to submit a particular field. The serializeArray() returns all the fields in the form. So, I tried something like this to prevent the password field being serialized.
This works great but the ajax submission doen't work.
I'm having troubles with an existing J2EE application (which uses Dojo) and in which I'm gradually introducing jQuery. The specific issue is with the malsup Form plugin and the JSON returned from a form submission: the error callback is always called, regardless of what happens on the server side, and the error is always "parsererror". I'm using jQuery 1.4.2 and the 2.45 version of the malsup Form plugin.
For example, given the following code:
$(document).ready(function() {
var options = {
dataType: 'json',[code]....
the server receives the submission and handles it without errors, then in the browser I always get the same alert from the processAddressEditSubmitError() function, with an "Invalid JSON" message:
pStatus=parsererror
pErrorText=Invalid JSON: {"nickname":"trytrez","success":"success"}
However, the JSON looks OK for me (and http:[url]...agrees that it is valid).
I'm using this script above the </body> tag in a CC instead of using IE expressions to fake position fixed in IE 6.
Code JavaScript:
<script type="text/javascript">
window.onscroll = fixedIE;
[code]....
I'm having a few problems... none are caused by my browser, so they are proving hard to troubleshoot. A user has pointed a couple out to me.
I have this code as part of a script:
(I have inserted hard breaks to make the post look better)
----------------------------------
window.open("http://www.site.com/loading.htm","confirmation","screenX=10,screenY
=10,left=0,top=10,toolbar=0,location=0,status=0,menubar=0,scrollbars
=1,resizable=0,width=250,height=250");
document.subForm.submit();
----------------------------------
"subForm" targets "confirmation". The user is getting two windows instead of one. One contains the initial window document and the other contains the form action. Also, she says they are both big... the size (of at least one) should be 250x250. She is running AOL 6 and IE 5.5 on the related computer.
Perhaps a timeout would help the 2 window situation? Why are the windows big and not 250x250? If you know what's going on please let me in on it.
This same user has a laptop that runs AOL 4 and IE 4 (she thinks). On that computer the form is submitting to one window, but none of the data is making it to the new window. I am guessing this has to do with the way I have the "form" and "table" tags within the javascript document.write statements. Does anyone know a good web page on this subject? OR What else the problem might be?
Ok, next issue! I am trying to submit a form using Netscape 4.03. When the submit button calls the related function I receive: "subForm is not defined". Here is the line that is throwing the error:
----------------------------------
eml = subForm.email.value;
----------------------------------
The final problem is regarding the same form. When I hit the submit button in N6... nothing happens.
I'm working on a project for my company that will be deployed next week. In a nutshell, we have a bunch of touchscreen computers that we are using as kiosks for an internal event. The various screens have been build in XHTML/CSS, with a smidge of javascript for the few points of interactivity that aren't being handled through the HTML.
I just started dabbling in Javascript for this project about a month ago, and I think with enough time, I could probably figure this out. But I'm feeling crunched on time, and I thought someone here might have a simple solution.
So here's where I am. The "boss" doesn't want to use the built in browser alert/prompt boxes, which is fine by me, since I can just skin up some alerts in CSS, and attach JS functionality to them. But I ran into a snag in one of them. On each kiosk, we are placing a transparent DIV in the upper corner that invokes a password prompt. If the password matches the password stored in the JS, the kiosk browser window closes (window.close). If the password doesn't match, the user is informed of such, and remains in "kiosk" mode.
For the password box, I've written in a hidden box in CSS, who's display value is set to visible when someone hits the hidden area in the upper corner. That works fine. The box itself is a <p> that simply prompts the user to enter the password to continue. I have a form with a text field as well as an "ok" button.
Here's where things stop working. If I pre-define the value of "var password" to be the correct password, clicking the OK button works as expected. But if I try to use the user input from the form, I get an error. I'm happy for someone to start me from scratch if the below code isn't workable. Here's what I need:Password prompt box that's skinnable in CSS.Value checked against stored variableIf accepted, window closes.If denied, user is informed and prompt box is returned to hidden state.
[Code]...
One note, before I toss this to you all. If it's easier/better to simply include the error message as part of the FORM, instead of it's own separate box, I'm A-OK with that.
I'm using simple form validation, found online, to check certain fields before submitting. The problem is that, although the script detects the error/missing field/wrong syntax and pops up the corresponding alert, after the user presses OK in the alert box the script continues and sends the form - which of course is not valid.
HTML PART:
<input name="Submit" type="submit" class="textfield" value="Register" onclick="checkitems();">
JAVASCRIPT PART:
function checkitems() {
valid = true;
if ( document.registration.Onoma.value == "" ) {
[code]....
user fills in a form (selects files for upload, writes a post, etc.) and submits it - without page reload she gets a response from server (error, unsupported file type, inappropriate language, success, etc.)I imagine first, submit-without-reload, part is done via the form.target property like this: - iframe is either created dynamically with JS createElement or statically. But in any case it should look something like this:
<iframe id="#iframe123456" name="#iframe123456"></iframe>
- form, also created either dynamically or statically:
<form action="process.php" target="#iframe123456">
<!-- inputs of various types -->
</from>
As for the response/result part, server dumps its reply into the targeted iframe, so I have three alternatives:- use iframe's onLoad (onReadyStateChange) event: attach a get_data() function to it.- frequently/manually poll iframe for data using setInterval(get_data, milliseconds). - inject some script into the server response that makes iframe itself call get_data() .how I can check if an iframe has data in it.I use the following script to get the iframe's inner document object (excerpt from get_data() fucntion ):
if ( iframe.contentDocument ){
doc = iframe.contentDocument;
}else if( iframe.contentWindow ){

I am trying to validate a form field using a $.post request and am having an issue with timing because of the synchronous property of the post I assume. If I put in an alert, it works fine because the post has returned in time to stop the form submission. Here is the original way I did it but the form is submitting before I can send the return = false.
Code JavaScript:
$('form#form-oidupdate').submit(function(e) {
var srchstr = $('form#form-oidupdate input').val();
var passdata = {'type': 'availability', 'srchstr': srchstr};

i have a form that has both front end and backend validation (php)
basically i got the code off the net, and it needs the submit button to be of type "button" rather than "submit"
and obviously the form doesn't submit if javascript is turned off
i'm not a javascript expert, on the button it has onClick="formvalidate())"
and in the javascript it has
if form is ok form.submit() or something to that effect
now is it possible to use a submit type so that if javascript is turned off, the form will still submit
but won't submit if javascript is on and the form is invalid
does it have something to do with the onSubmit attribute for the form
currently there is none
because we have the backend validation it doesn't really matter if javascript is turned off but it does matter if the form can't even be submitted at all
On one of our pages, when the page loads, the form submits. The only problem is, we need the submit name to be name="submit". When we use this, the form doesn't autosubmit. When we use something like name="submit1", it submits, but our form doesn't work properly, since it's requiring the submit name="submit".
<html>
<body onLoad="document.loginForm.submit();">
<form action="index.php" method="post" name="loginForm" id="loginForm" >
<input name="usrname" type="text" value="theusername">
<input name="pass" type="text" value="thepassword">
<input name="domain" type="text" value="somedomain">
<input name="submit" type="submit" value="Login">
</form>
</body>
</html>
Any ideas how we can still auto-submit, but use the submit's name="submit" parameter?
I have an online form for doing proofs and have a problem: My form page collects all the information the user has entered. the form has 2 buttons
When you press the PREVIEW button I need the form submitted to open a new _blank page. This page shows a pdf with the info in. This is so the user can close this page down and still have the forms screen behind to make any changes.
When the user presses SUBMIT I need the form to submit to a _self page so that the form page becomes a thankyou page and the user cant make anymore changes to the details he has submitted.
The forms must submit as the online pdf proof wont work without a submission.
I have a very basic postcode validation script which works brilliantly, however I require a new validation adding to this. I want to single out people with specific postcodes, to be mor specific anyone with a Milton Keynes postcode should receive an alert when they submit the form before it goes to the serverside action page.I can write a regular expression which detects the postcodes i want to look for, however i am lost as to how i create an alert before the form is submitted without cancelling the submission.My current validation for the postcode looks like this:
Code:
var regExpressPostcode = /^([a-zA-Z]){2}([0-9][0-9]|[0-9]){1}([ ])([0-9][a-zA-z][a-zA-z]|[0-9][0-9][a-zA-z][a-zA-z]){1}$/;
function checkForm(aForm) {
if (!regExpressPostcode.test(aForm.shipPostalCode.value)){

I'm trying to prevent the submission of a form but it apparently isn't working.
Code:
elForm.onsubmit = function(){
object.GoAJAXGo(elForm);
return false;
}
The return false bit I believed would prevent the submission.
I have a form which houses basic inputs, as well as a few multiple select forms.
I need to parse all the 'values' which are in this multiple select form (it
gets manipulated dynamically client side). I wanted to create a function
that loops through all the form elements, and if the type 'select-multiple'
is detected, gather the VALUES of each <option> inside it.
The bit I'm stuck on is then how to reconstruct this into a form submission.
Preferably I wanted the data from the 'select-multiple' element to be
submitted as comma delimited, eg 14,12,512,63,62 which would later be parsed
by PHP.
I was considering reconstructing a query string and submitting that as GET,
but I'd prefer to POST it along with the other data (such as INPUTS etc)
which do not need to be changed.
Can I somehow attach some 'hidden' type data onto the end of the form
submission at this point?
I have a quick question - if I have a form which refers to a javascript when
its submitted using:
<form name = "fred" onsubmit = "test()">
and this function creates a popup window to display information in, I find
that after the window has appeared, the focus moves back to the form and the
text box used to gather user input clears. The clearing text box isnt a
problem, but the moving focus is. Is there a way to make it so that the
window containing the popup information stays on top? This problem doesnt
ocurr when I use the submit button to call the javascript function.
I have a form in which I have this link :- <
href="javascript:submitform(parameters );"> . In the JavaScript
function submitform, there is the code for submitting the form.Thi
works fine with single click on both IE,NN6.In IE the form is submitte
only once even for double click.But if you double click on the link i
NN6, the form is submitted twice. This causes problem. The workaroun
for this was that we set a flag(indicating form submission) in th
submitform function, we also set a timer which calls the functio
resetflag after 3 seconds.So any click within 3 seconds of the firs
click will be ignored (so that the form is not submitted for the secon
click).
function submitform(params)
{
if(flag==0)
{
flag=1;
timeout = setTimeout('resetflag()',3000);
document.form1.action = someURL;
document.form1.submit();
}}
function resetflag()
{
flag=0;
}
I am trying to use jConfirm to make sure a user wants to post a form. My selector is working as well as the jConfirm (I have tested it well). However, it is not submitting the form. The form action is PHP_SELF and I am simply echo'ing the POST vars. Without the js, it posts fine.

I've got a form that I need to go to two different places. First, I need it to submit a portion (but not all) of inputed data to one url (url.php). If that is successful, I need it to submit another portion of the inputed data to another url (url2.php). The trick is, I need the information from some fields to go to both places, but with different names.
Here's what I'm doing:
$(function() {
$('form').submit(function() {
return false;
$.ajax({
type: "POST",
url: 'url.php',
data: $('.string').serialize(),
success: function(){
$.ajax({
type: "POST",
url: 'url2.php',
data: 'firstname='+$('#Contact0FirstName').val()+'&'+'lastname='+$('#Contact0LastName').val()
});
}});
});
});
I have the information I need to go to url.php serialized by class (.string). Then, I try to make a string out of the data for url2.php. What seems to be happening the form is submitting ALL fields to url.php, ignoring the serialized string I told it to use, and then submitting ALL fields to url2.php, again ignoring the string I told it to use.
How a validation can be applied so that, an Instant message should alert a user that any invalid value is entered by the user in the textbox at a time , before submitting a form ?
View 4 Replies View RelatedI have an application that is used by people on my work network and the general public (not on the work network). We experienced an error where a form is submitted using form.submit(); in javascript, but none of the form data comes across to the application server. The request is executed (the servlet processes the request), but the application server and related code gets no data.
It is like we send servlet.do?arg1=val1, but what we get is just servlet.do.
People using this application on our work network, do not experience this issue.
Has anyone ever experienced anything like this? I think it's related to the network/proxy configs, but thought I would ask in a JavaScript forum to see if someone else has seen something like this.
delaying the form submission for 3 seconds. When the submit button is clicked I have a animated loader image that becomes visable and I want the visitor to see it for a few seconds before the form submits.I have the following so far, however the issue I am having is that the action when the form submits no longer is processed. But if I take the timeout out the action is processed
Code:
<form name="checkstatus" id="checkstatus" method="post" action="<? $_SERVER[PHP_SELF] ?>" onSubmit="return delay(3);">

I have a entry form which inserts data 2 DB. while the user entering info if he wants to click on any url in left nav pane there should show message: the data won't be saved if you navigate from this page. I have written some code..it works fine but if i Hit submit button on the form It wont submit, still gives the same popup -the data won't be saved if you navigate from this page.
HRE IS my code:
BUT this works only if i try to navigate from page. But it still prevents the submission.
I wonder if anyone can assist me here. I am trying to find the best way to validate a field against another field. In this case I need to make sure when the user enters the date of birth that the date is not prior to another date in the database (admission date). I would like to do the validation on submit before the other data from the field is submitted to the database.
I have seen a lot of forms validation that can compare the inputted value to a range of values, but I need to say "is the birth date prior to the admission date? If NO then give a message to the user to recheck the date". Sounds easy, but I haven't found a clean way to do it.
I have a small search appliance on my site that uses the following HTML:

<input type="hidden" id="search-url" value="/search/search.aspx">
<input type="submit" class="search" name="submit" id="search-submit" value="GO">
</form>

I am attempting to create a stop in the form action if someone leaves the input blank or with the predefined "Search" however, once the alert pops up and a user presses "OK" it still attempt to submit the form.
I am trying to combine a php form submission with a javascript function.Basically my form includes an address and UK postcide and I need to get the longitude and latitude of this address using the google map api. I have a javascript function that performs this geocoding.My problem is that I need the following sequence of events to occur.
1. User completes form including mandatory address and postcode
2. User clicks on the "Submit" button
3. Javascript function is called to retrieve the longitude and latitude
4. If successfully retrieved the longitude and latitude, submit the form data including the retrieved longitude and latitude.
Here is my javascript geocode function
Code:
function geoCode(location) {
if (location != '') {
localSearch.setSearchCompleteCallback(null,[code]...
Code:
<form name="myform" method="post" action="" onsubmit="return geoCode(document.getElementById('postcode').value);">
This is not working and it appears to just immediately submit the form without going into the following bit of the javascript function
if (localSearch.results[0]) {
