JQuery :: Confirming User Action And Then Processing Form?
Oct 13, 2011
I have a form that has two input buttons. One of the input submit buttons is being used to delete data from a database. Whenever a user clicks that delete button I am trying to make it so that a confirmation message appears that confirms that the user wants to carry on with the action. Then if they click Ok, the form should continue processing otherwise it will fail.
<form action="<?php echo $_SERVER['php_self']; ?>" method="post" id="data" name="data">
<fieldset>
<table>
<tr>
<th>Check</th><th>Id</th><th>Added</th><th>Method</th><th>Host</th><th>Port</th><th>Time</th><th id="shell">Shell Location</th>
[Code]...
Currently, the confirmation message works great but I can't get the form to submit once I click.

I am trying to design a system that allows users to draw on a whiteboard with different colors, save their drawing into hidden input boxes in the form on the page, then they can click Save Logo to save it to process it through PHP. I have the whiteboard that allows them to draw, but I am lost as to how to get the thing to populate the hidden input boxes.
So, I have the following code:
<HEAD>
</HEAD>
<BODY>
[code]....
What I am trying to do is use the function mousedown(e) to include an event to update a hidden input box with the value of the TD's background color that the hidden input field is attached to, so that it can be tracked when the user hits Save Logo at the bottom of the page. When they hit Save Logo, I want the form to post to itself, go through each of the input hidden fields and capture the color for each table cell, then generate an image based on the generated array, save it to a file on the server with the user's $_SESSION['userid'] as the filename + .jpg.
The problem is, though, that I do not know how to tell JavaScript to do this in the function mousedown(e) code. Also, look in the function table_create and see if I am naming the hidden input boxes correctly; not sure if it will generate the wanted result.
Just a note: I can handle all the PHP handling of the form, I just need help with the Javascript.
Edit: I attached the entire script/page to this post because so many functions rely on each other to operate, and I'm not exactly sure which function will need to be modified to get the desired result. Also, you can copy the code to a .php file to see what it looks like (as that may assist in demonstrating exactly what I'm trying to do, visually).
Edit 2: I suppose what I need to find is how to get the JavaScript to assign a value to the hidden input field that has the same id as the TD field that it needs to be linked to.

I have come across a very interesting problem that seems to be impossible to solve. Basically a web application that I am working on relies on a JavaScript function called go to change the input named view to the page name and submit the form. This form's type is post, so no values are included in the actual URL string. There is also another input called action and it's value is view. This is to tell the application that the user would like to view a page. The problem is because of the variables being of method post, page refreshes and back and forwards return errors because the post variables view and action aren't sent with the required data. To somewhat solve this problem I have created a feature that tells the application that if the post value page is empty then to try and get a GET var called page. To insert this var into the go javascript function I simple add this code
document.go.action = document.go.action+"&page="+page;
This line basically adds &page=[page] to the action of the form. The problem is, this code doesn't work because action is also the name of a form element. Referencing document.go.action refers to the input element named action and not to the form's action. Changing the named of the action input value is out of the question (Way to much changing of code, and possible room for error). What can I do to change the action of the form without referencing the input named action. Here is my go form and the JavaScript code:
<form name="go" action"index.php?sid=123" method="post">
<input type="hidden" name="action" value="view" />
<input type="hidden" name="view" value="" />
</form>
[Code]....

I have to make an application that works on pc and apple mac.
Therefore I am investigating if it's possible to use html/javascript.
The database has 10000 records and is sequentially searched. This may
take 20 seconds or so. I want the user to be able to quit the search
and also I want the outputscreen to be updated immediately when a hit
is found and not wait until the complete search is finished.
The problem is that the click-event of the 'Cancel-button' is
processed after the search is finished. Is there something like
application.processmessages (similar to Delphi) so all pending events
are processed?

I want to display three sets of images on a Web page, and I want to use only one jcarousel to do it. I want to change the list of images based on the user clicking on one of three links, each representing a set of images. How do I do this? I know I can edit the DOM to modify the list of items, but how do I call jcarousel's reload() function? I thought of using three instances of jcarousel, but that takes up too much screen space and requires the user to scroll too much.

Ok this is what I want to do
I have a link
<A HREF="blah">Delete</A>
when I click on it I want a confirm msg to pop-up and if the user presses NO then it won't load the page if YES then it will delete. I tried to do this but I don't know enough about JS yet so I gave up. Plus it's 2:00am here.

I have a database site I am currently designing, and would like to use a single page with forms in external html documents to undertake admin tasks (eg. add/remove records etc.)
I have managed to successfully load the form html into the necessary div using the $.load function, however, when I try to process the form, with this code:
$("#add_form").validate({
debug: false,
rules: {
maker: "required",
[Code]....
which asks 'process_form.php' to process the data, it doesn't seem to send the data in the form to the page. to confirm this, and whilst trying to get the system to work, the 'process_form.php' consists of 2 lines,:
echo $_GET['maker'];
echo '123456';
(ie. one line to return a string literal, and one line to return one of the variables which SHOULD be passed by the form)
This results in just the 123456 string being returned.
I have tried several things: loading the script above in the head of the 'parent' html page (ie. which the form is loaded into); - does not properly fire at all;
loading the script 'in-line' in the imported html - this leads to the result given above; running the script in an external script.js file through an onsubmit directive on the form...does not appear to properly fire the script.

By luck I had somehow found a way to collect data with a form, perform
calculations with JavaScript and display the form and calculated
results on the same screen.
Now I can't figure out how to do that again. The only methods of
reporting the calculation results seem to display a completely new
screen/window.
I just want to collect some numeric input data with slider widgets or
text boxes for an alternate method and display additional calculated
results 'real time' as the slider is adjusted. If this can't be done,
after a text box entry is made. Ideally the results would display
without a 'submit' button click.

I have a very weired problem (which is not easy to describe.. but I'll do my best):I have a html page with several forms , only one of the got the action="ComputeAndReturn" and the other forms got only name="" tag.the problem is that after i submit the form with the action , and than after a computatioon it returns to the original page, now... if i will submit any of the forms without the action=.they will act as if they were defined action="ComputeAndReturn" (altho they are not!)if they were defined from the first time with action="anything", and than i would submit the form with action="ComputeAndReturn" this problem would not appear (the other forms will keep their action="anything" and would not "imitate" the action= "Compute AndReturn" to them selfs...
any ideas how can i keep my forms without action="" , cause all i need them to do is be submitted to pass the submitted value to other form inside that page.[code]

I wish to carry out standard form validation (i.e. is it a date?, is
there a value in the field, is it a number) using the onBlur event
rather than the onSubmit event. This (of course) leads to problems when
cancelling an edit as leaving a field to press the cancel button will
trigger the onBlur event and therefore the field validation. Is there
any way to know the destination field / button that caused the onBlur
event? In Ingres ABF/W4GL (mid eighties language of similar
functionality to javascript) there was an available attribute called
the targetfield so the code could run...
onBlur myfield =
{
if (targetfield != CancelButton) {
carry out validation
}
}
Is there something similar in javascript or will I have to program
round the houses i.e. onBlur records which validation to run and
onFocus runs the validation (unless it's a cancel button)?

As this forum has been so helpful before, this time it's a JS question:I have a list of checkboxes from which the user can select 1 or more to check and perform an action upon.Thus, all checkboxes have the same "name" (in ASP code, since it's DB-related):
response.write "<input type=checkbox name=""FieldName"" value="&obj("OrderID").value&">"
I call JS using a button:
<img src="images/TrashBin.png" border=0 onclick="Delete(document.FormName.FieldName)">
[code]....

I have an web application (PHP backend) where I want to initiate multiple requests to the same server (to different php functions/files) and asynchronously update the response on the page (the call back function is same for all the requests).
What is the best solution for this ? Is it better to
a) call multiple server calls from the java script file? if so Do we create multiple http objects ? can someone point me to the few examples ?
b) call one Php service and have the php fork the multiple requests on the server side. I am not sure if this can be done multiple requests be done asynchronously on the server side ? and if so how to dynamically update teh resultant page as each request finishes?

I have a snippet of javascript to check and make sure all the fields in a form are filled in. If they aren't then it shows an alert box telling you to put something in that form. If all the fields are filled in then it submits the form. That piece of code is this:
Code:
function checkFields() {
var errors = "no";
if(document.street_team.email.value == "") {
alert("Please enter an e-mail address..");
errors = "yes";}
if(document.street_team.name_first.value == ""){
alert("Please enter your first name.");
errors = "yes";}
if(document.street_team.name_last.value == ""){
alert("Please enter your last name.");
errors = "yes";}
if(document.street_team.loc_state.value == ""){
alert("Please enter your state.");
errors = "yes";}
if(document.street_team.loc_city.value == ""){
alert("Please enter your city.");
errors = "yes";}
if(errors != "yes"){
document.street_team.submit();}
}
Then i used a button to start the script. That code is this:
Code:
<button onClick="checkFields()">Join</button>
The problem is that if you don't have something filled in and the alert box pops up, once you click "ok" it still processes the form. Any ideas on how to keep it from doing that?

i have a form like this on a page called emailform.htm:
<form method="post" onSubmit=NewWindow()>
<H3>From: <input type="text" name="from"></H3>
<H3>Message: <input type="text" name="body"></H3>
<input type="submit" value="Send the Message">
</form>
when submitted, it calls this function:
function NewWindow(){
window.open('sendmail.php', 'newWin', 'scrollbars=no,
toolbar=no, width=200, height=200');
}
two problems:
1. the form values are not getting passed over to sendmail.php.
2. after the popup window pops up and loads sendmail.php, the original page, emailform.htm, changes to an error page.
so, what do i need to do to get the form values to be passed, and how do i keep the original page either from changing at all, or, if thats not possible, get it to simply reload itself.

I feel like I've been server-side programming so long that I completely forget how client-side works. I have a super simple form:
Code:
<form action="page2.html" method="post/get">
First name: <input type="text" name="firstname" /><br />
Last name: <input type="text" name="lastname" />
<input type="submit" value="Submit" />
</form>
Is there a way to use Javascript on "page2.html" to access the contents of firstname and lastname and display them?

I have a web application in which I want users to be able to submit a form. Something like this:
Code PHP:
<form method="post" action="index.php">
<input type="text" name="text" value="" />[code]....
Then when it is submitted, the data will be processed and the script which is processing the data will echo some data on-screen based on the data from the form.I need this to happen in an AJAX manner, ie: the page won't need to reload.how to go about doing this? I'll be using jQuery on the same page in case

Here is one I cannot seem to figure out. I've got a set of text boxes with the change event bound to a function that will do some validation and add some numbers together. If the user enters something that is not a valid number I want to alert them and then put the focus back on the offending field.
My problem is that the event that I'm capturing is not the actual tab key or mouse click. So even though I set the focus in my event handler, the initial event that started the whole thing still moves the focus to the next field or where ever the mouse was clicked.
I've tried preventDefault, stopPropagation, returning false, and a bunch of other things to no avail. I hope it is something I'm missing or not seeing. If not it seems like my only choice is to capture all the events (key presses, mouse clicks etc. and handle them all which seems rather tedious.
[Code]..
