Unable To Validate Html Forms Using External Js
Mar 24, 2009
I am a newbie trying to generate an alert message when a user leaves a username filed blank in an html form using an external javascript. Following is the code for html file.
[Code]....
However, if I swap the positions of the username and first name i.e. place the first name before the username, I do get an alert message if the first name is left empty. I do not wish to hijack an existing thread. Please let me know if there is an existing thread on this issue..(I could not find one).

I am rather new to JQuery and would like to use it with php. I ran into problems when my html is not static, I generate php forms on the fly using my php script and JQuery just doesn't seem to validate those forms. When put the same form in static html file JQuery works like a charm. What could be wrong? Does JQuery need a page to be static? Right after I load my php page firebug reports that $(document).ready(function() { is not a function and JQuery is not defined. I have loaded the necessary JQuery libraries.

I want to validate(eg: empty validation) my web forms using javascript. How can I use a single javascript function to validate all the text boxes in all the forms. Or else do i have to write seperate functions to validate each web form

Order entry project. I am using an iFrame to pull external forms that I can not change. Once our employee enters in the information and submits I would like to redirect the existing window to a new page.
I've tried many variations of:
<script type='text/javascript'>
function iHistory() {
var hist=history.length;
if (hist>1){
parent.window.location = "orderentry.php";
}}
</script>
Since I have no control of the external form I have been using OnLoad() in the iFrame tag to call iHistory(). The script works great unless the browser history is >1 If possible, I would like to also setup like a 5 or 10 second delay so the employee can see the framed confirmation page before redirect. So the function needs to check current history.length, when that changes delay 5-10 seconds and redirect parent window to orderentry.php

I know that this must be quite trivial to most of you, but my skills
in JavaScript are weak.
I am looking for a way to validate all forms throughout a website
through one validation script.
How do I determine the form's name (or id) value to implement
conditional validation?
i.e. if (form1) { validate like this }; if (form2) { validate like
this };

When I add a tab, whose content is a form. The form is loaded by ajax $.ajax('url'); On ajax complete, I add a custom method for validation, which is supposed to get called when the "Upload" button in the form is clicked, but it never get called. I have searched and tried multiple things for two days now, and nothing works.

I've a page that has 2 forms. If the user clicks the bottom form the validations appear and everything goes red but the Top form is a required field but it doesn't as it's a separate form. How can I validation form0 and form1 together to show to the user the required fields. When the user clicks form0 it goes over to a pagedLIst, the user returns and textfield gets populated with the product that as selected. So when they hit form1, that value gets passed through as a hiddenfield..
<form id="form0">
...text box input to search for your product, returns to this page populated the found product
<input class="button" id="FindProduct" type="submit" value="Find Product" name="action"/>

I am using a variation of the multipage form in the demo and run into a small problem with the pageRquired function. Seems it does not validate correctly if you add any custom selectors after the pageRequired. I am trying to make one field required depending on whether another field is blank. E.g.:
class="{pageRequired: '#field1:blank'}"
In this case, the validation is completely ignored, even if I have {pageRequired:true}. It will only validate if I have class="pageRequired" without the curly brackets. However, if I set it up in rules, it will make the field2 required regardless of the value of field1, e.g.: $(document).ready(function(){
$("#myform").validate({
rules: {
field2: {
pageRequired: "#field1:blank"
}}, debug:true
});
On a whole the multipage validation works very well but not with any custom selectors such as :blank, :filled etc or by using curly brackets in the class. Is there a way around this? I would really prefer to use inline validation using class statements and still be able to use custom selectors. View this message in context: [URL].

I m aware of various ways to validate forms using JQuery, but here I have a complex thing, and i need the most optimized code for it... Basically I have a form made up of rows each containing a number of input text fields which are repeated on a the following rows however of course with different IDs and names... There is no need to fill all the rows, but it is necessary to fill all the fields of a specific row. Now I was wondering, how can i make sure that each row is properly filled? knowing that some rows will be totally blank [which is okay]

I need it to check that the name, email and message field have been filled out (which currently works fine) but also to check that the email is a valid address. This is my attempt at doing this, it works with the fields not being filled out, but does check that the email is valid?

I've used the excellent validate plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) to add JS validation to forms. I'm aware there's a built-in setting to validate an email address. However, I'd like to validate a list of email addresses, and I don't think the plugin contains a built-in solution. What's the best way to implement this?

I'm trying to develop fast, simple, html-based front ends
for some Windows application programs. My idea:
1. Use html forms to let users supply run parameters (title,
run options, etc.)
2. When the user presses a submit button:
a. The selected options for all the form fields are
written to an external file (e.g., c:projectinput.txt)
b. The application program, say, prog.exe, is executed.
This program then reads the run parameters from the file
input.txt and proceeds. Code:

I see it working in the demos I found this documentation
You can avoid having to duplicate the plugin settings by modifying the defaults. Use $.validator.setDefaults({…}) to override multiple settings at once.
But I do not understand what I have to do to make this work

I have an external page with some rudimentary html in the source code missing many tags.. a bit like the below. On a page hosted elsewhere I need to take the html from this external page and add and remove certain parts of it and add some styling such as line breaks before ^FIELD01. I've looked at jquery and AJAX but cant find anything to suit my needs. I think what I am struggling with most is having this page in a variable to then be able to edit it.
Code:
^BEGIN SEARCH FORM
<form name="dancesearch" action="JJList.html?PHPSESSID=604918b69ab9936e638b5d48cdc142a3&xt=673">
^FIELD01: Dance Name<input name="ts" type="text" size="20" maxlength="25" />

question1 : can i access form 1 variables in form 2?. if so how?
question 2: when form2 action is saveci.jsp . can i access form1
variables in saveci.jsp. if so how?.
basically when form2 is submitted, form1 variables should be accessed
in the jsp which processes form2.

I am currently designing an HTML page with a form with a post method.
The page is calling itself so with the details that are passed will
vary how the page will look i.e. number of results from the sql query
that is being run. I'm trying to catch these using a javascript
function which is:
var qsParm = new Array();
function qs() {
var query = window.location.search.substring(1);
document.writeln(query);
var parms = query.split('&');
for (var i=0; i<parms.length; i++) {
var pos = parms[i].indexOf('=');
if (pos > 0) {
var key = parms[i].substring(0,pos);
var val = parms[i].substring(pos+1);
qsParm[key] = val;
}
}
}
and then just calling the array to get the value, in this case
qsParm['num_res']. The above function doesnt work for post but does for
get. I'm fairly new to javascript and am assuming this line is at
fault:
var query = window.location.search.substring(1);
but I'm not sure what it should be.

I am trying to create an HTML form in which user will enter different items (he wants to purchase) in text fields. One text field is used for one item. Now it is not known in advance how much items the user will purchase so we cannot decide the total text fields required in advance. Is is possible to increase the number of text fields (using JavaScript) one by one if the user requires more fields

I'm having some trouble naming variables in javascript. Actually, my html has multiple form names (form, form1, form2, etc..., and im just having trouble understanding how to access elements within.For example: I get error:Message: 'document.forms.form.bname' is null or not an objectWhen I use the following code:
var bname = document.forms["form"].bname.value;
And when I try this:
var bname = document.form.bname.value;

I am loading an entire page in ajax, but I just want to load a fragment from it. Using the .load() function, you can do this by adding a selector after your url like 'getPage.php #myDiv' etc, how to do it using the .ajax method.
I did some googling and found this solution:
$.ajax({
url: 'AjaxTest2.htm',
data: {},
cache: false,
[Code].....
I'm trying to get the "d1" div to be populated with the contents of the "my2" div on the second page. I don't want to use the .load() function, I want to use the .ajax() function. I can get this to work if I just use: $('#d1').html(data); instead of $('#d1').html($(data).find('#my2')); but the former results in the entire html contents of the second page being placed into the "d1" div, and I only want the fragement.
