Form Always Submits - Even If My Function Returns False - Alert() Doesn't Seem To Be Working
Nov 6, 2009
I have a simple form here with a function to validate it, but I have no idea where I'm going wrong. I'm very familiar with ActionScript and C++, so I get the coding aspect of it, but one thing I'm not familiar with is how exactly JavaScript and HTML communicate. The problem is that this form always submits, even if my function returns false...but I can't even see if it returns false anyway, because alert() doesn't seem to be working either.
Here's what I have for my HTML:

This is a simple email form validation, with javascript. I first coded the basic 'have you filled in the field" stuff and that worked great, the error message poped up and the form would not submit until corrected.I then put together a email validation function using reg ex, and things went slightly awry. The reg ex works, so hat is cool, but after catching an invalid email address, it submits the form anyway.Following the logic, you can see that the form gets validate, then the email address is validated, then the form validation function returns true, which is probably why it is submitting with the bad email address.I never seen an example of this, but can you put a called function into an if statement? So it would go: validate the form, then if the email validation function returns true, go ahead and submit.Anyway, here is the code:
JS code:
function validateForm ()
{

Lets say I have a MySQL value of 4... and I have a HTML INPUT field.. Is there a way to make it so that if a client tries to submit a value higher than 4, then they will be returned a message? Something like:
<SCRIPT type="text/javascript">
function validateForm() {
if (document.forms["form"]["quantity"].value== (+$row['quantity']) {

I am trying to test changes to my site (made only on my local machine so
far) in IE v6, Mozilla 1.6, and Opera 7.5.
When I test "navigator.javaEnabled in IE it corretly reports true/false
depending on whether javascript is enabled.
However, both Mozilla and Opera *always* return false. How can I properly
test to see if javascript is enabled/disabled in these two browsers? (If you
have a reference on the web, please point me to it as I've spent several
hours trying to find what I need.) Code:

When I create a new div and insert it with .append(ndiv) to an existing div ndiv.width() returns the width of the parent div instead of the actual value. This is the same in FF4 and IE9 so I suppose this is a regular behavior and I just don't realize how to deal with it.

In the below code, the alert message returns in one instance: 'someAnimal is [Mammal "Mr. Biggles"]' I don't understand how this is possible. We pass as an argument 'Mr. Biggles' to the Mammal constructor. Then assign it to the object name property. But then it ends there. There is a function called toString which will return the alert. But the toString function is not being called like this: alert('someAnimal is '+someAnimal.toString()); If it was like how it is above, it would make sense to me but now it makes no sense to me because I don't see where that toString() is being called - I only see that it is prototyped to the Mammal object.
Code:
function Mammal(name){
this.name=name;
this.offspring=[];
}
Mammal.prototype.haveABaby=function(){
var newBaby=new Mammal("Baby "+this.name);
this.offspring.push(newBaby);

I'm working through this example in a book I'm reading. I can't get the "return false" to stop the form from submitting, when the text input is empty.
Code:

<html xmlns="http://www.w3.org/1999/xhtml">

I have this function to add some parameters to my XSL and then
retransform my XML with it, resulting in a neatly filtered table. It
works great, but as soon as I take out the alert, it doesn't do
anything anymore, seemingly. This is the function: Code:

This JS code is on RoR+ImgMap site.I've tweak several portion of ImgMap, specifically around line 2205 of the file imgmap.js by adding code.so that when the user draws a shape, the focus will be set to the respective href field, instead of the default behavior - adding new row(imgmap form).

When using the code below the alert returns a value of null. In the past this has never happened, it has always returned the xml file I'm requesting. I have noticed a strange difference between browsers. This script is used to fill a form automatically. In its current state it works perfectly in opera, but does not work in firefox or IE (used to work in all the browsers). I'm by no means a javascript expert, am I missing something here?

alert($(myHTML).children("body").html());
Why does the alert return NULL, instead of "testing hope this work in html" ???

I need an html page that when visited automatically redirects the browser to return to the previous page it was on. here is the current code I have:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>[code]....
this works in firefox but in IE you have to press ok in the alert box before it returns. I admit I am a javascript novice. Any suggestions

I have this code in a function.
[Code]...
Alert 1 is to check if the program enters the function. And it does in all browsers. But when it comes to alert 2, Firefox does not execute the alert. So I assume there is something wrong with firefox executing the onreadystatechange. By the way this is the code for initAjaxObject()

I have a multistep jquery form that validates user input and then should send me an email. Problem is, right now, I can only get it to validate the first page, then it sends the email before the rest of the pages are viewed. I'm just trying to delay the submission of the form until the "submit_fourth" button is pressed. I've got $25 via paypal for the one who sticks with this one for long enough to come up with a workable solution.
Here is my code I know it's a lot, but I wasn't sure how much would be HTML code is in the second post in this thread (it was just too much to fit in one go).

i'm unable to do this with jQuery 1.6 but it works fine with jQuery 1.5.2 :
$('#comment-content')
.delegate('#chkb-status-review,#chkb-status-validate','change',function(){
$('#chkb-status-review,#chkb-status-validate').attr('checked',false);
$(this).attr('checked',true);
})
No error, just not working. Maybe i'm doing something wrong

I am trying to figure out the contains() selector, and I may be using it incorrectly.
Basically I am trying to check if the email input field contains 'invalid' in the user entered value.
So shorthand it would be like this:
if (email value contains 'invalid' when form submits) {
do something;
}
This is what I have:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>

I have a web page that has a very simple form. This form does not have a submit button I use an image element fro a form and the utilize the onclick javscript call. This onclick wil validate the form and then IF the form pass all the validation the script itself will submit the form by checking a error flag status and if no errors submit the form. That is the way it is supposed to work. Mine doesn't.

I am using a simple form to submit values to another website. This has been working without any problems. I now have added a second form to the page. I have separated the text boxes and duplicated the information from one form to another. The problem is, when I click on the link that use to submit the information, nothing happens. Before the addition of the new form a new window would open with the search that I had submitted. Am I missing something to point to one form or the other? The following is the code that i am using in the form that no longer submits.
<script language="javascript">
function submitPostLink()
{
document.postlink.submit();
}
[Code].....
