Form Onsubmit Fails In IE?
Mar 10, 2010
I have created a simple form for uploading text files.You can see two versions of this it at: http:[url]....The form created with static HTML, works fine in current versions of the major browsers.However the dynamic form, fails (only) in IE.It fails because IE does not send the file at all when the form is submitted.

I am trying to create a form that writes text to an HTML canvas when submitted. Eventually, the function that writes the text will be more complex. The problem is the text only appears briefly, because the function is only called once when the form is submitted. I want the function to be called continuously after the form is submitted.How do I do this? I have had very little experience with JS.A lame (failed) attempt...

I have two frames. Frame "search" contains a search form specifying
an onsubmit action like so:
<form ...
...
</form>
The other frame contains a <img ... where
the perform_search function is defined as follows:
<script language="JavaScript">
function perform_search() {
var frame = parent.frames.search;
var form = frame.document.forms.mainForm;
form.submit();
}
</script>
Now, when hitting Return in the search form, then foo() is called
fine. But when clicking on the <img ...
in the other frame, foo() is NOT called.
Is expclicitly calling foo() from perform_search() the only way to do
it, or is there a magic incantation that might do what I want?

One of the links adds a button to the form dynamically (and also removes it).I give the button an onclick event handler that also removes it from the page (basically just setting its parent.innerHTML='')A third link submits the form using a function (for validation perhaps).The third link submits the form successfully, EXCEPT when I have removed the newly created button by clicking on it. In this case the form.submit() is simply ignored although the function is still executed.This is essentially the problem I have: The link fails to submit after using the button to remove itself.If I hide the button using the first link and/or change the button's onclick to do nothing then I can still click it and the form submit succeeds.Here is the test code:

II'm running Joomla 1.5.23 and I've been trying to get validation on a component's form fields. In the header section, I'm properly loading the validator.js file, which contains the following:
//function to check empty fields
function isEmpty(strfield1, strfield2) {
strfield1 = document.forms[0].firstname.value
strfield2 = document.forms[0].lastname.value[code]....
My problem is that even if all fields are empty it will go to the next step.

I have been searching high and low and I can't seem to find an answer. I am new at JS and I have created an form and when I click the on submit button it resets all the fields. The fields are always blank after I click reset. I have been working on this for 6 hours.
Code:
<head>
<title>H10</title>
<script type="text/javascript" src="H10.js"></script>
[Code]....
It just keeps resetting when I click Submit. I see for a millisecond that the total appears but then disappears along with the amount I put in the input text box.

1.The user presses 'Submit Answers' button,which ends the exam and his result is displayed.This one is working fine.
2.The other is the timer expires.the exam finishes and the user's result should be displayed.This one is giving me a problem.
When the timer expires I want to run the onsubmit() function to assign values to hidden form inputs ,but I am unable to do so.How do I do this.Everything else with the timer function is working fine. Only a snippet of the actual code is given here,because the rest of it is ,I believe,irrelevant to the discussion.

I just noticed that if I use a "submit" button the "onSubmit" function call
will be invoked. But if I use a button to call some other javascript and at
the end of that javascrip I do something like "form.submit()" the "onSubmit"
function call will NOT be invoked. I thought that was wierd. Can anyone
shed some light? Here's a small example:
<script type="text/javascript">
function subform()
{
document.frm1.submit();
}
function checkform()
{
alert('checking form');
return true;
}
</script>
</head>
<body>
<form name="frm1" method="post" action="" onSubmit="return checkform();">
<input type="text" name="txtname"><br>
<input type="submit" name="btnsubmit" value="submit"><br>
<input type="button" name="btn1" value="go" onClick="subform();">
</form>
</body>

I want to time how long it takes one of my form scripts to run _after_ I press the submit button.
My php (to start the 'stopwatch' running) looks like this:
<?
$mt = explode(' ', microtime());
$script_start_time = $mt[1] + $mt[0];
?>
So I want to have an input field that looks like this:
<input type='hidden' name='script_start_time' value='$script_start_time'>
BUT $script_start_time must be populated at the exact moment the submit button is pressed, and not when the page where the form is first visited. Which is why I need a client side solution.

I am in a JavaScript college class and right now we are learning about form validation, well before server side validation, and I am having an issue with validating the field if the user updates it and hits submit again. The red .setAttribute function is not removed. My code is below, please excuse the noobness I am displaying here.

I have created web pages that do client-side form validation using the
onclick directive. E.g.,
<form action=other_page.cgi method=post>
Enter your age: <input name=age>
<input type="submit" value="" validate_form()">
</form>
where validate_form() returns true or false depending on whether the
user entered a valid age.
This does what I want almost everywhere (e.g., Firefox on FreeBSD,
Safari on Mac, IE on Win2000) but recently I have become aware of an
exception: IE on WinXP.
On WinXP's IE, validate_form() is called (and will display an alert box
if that's that's what I coded), but whether it returns true or false,
the form is submitted. (Then we do the server-side validation and throw
up an error page, but I'd rather catch this client-side.)
So the question I have is: why is WinXP so weird about this? Previous
versions of IE didn't do this.
While looking into this, I've discovered I can also do an onsubmit check
in the form tag, e.g.,
<form action=other_page.cgi method=post
validate_form()">
Is onsubmit new or has it been around for a while? Can I trust old
Mozillas on Linux to do the right thing with it? Windows is actually a
small portion of the target audience, but I like to make things work for
everyone.
Does it make a difference if the form is submitted to the same page or a
different page? I don't have ready access to Windows XP to test this
out.

I'm trying to create a form whose onsubmit returns false if the form
should not be submitted. Normally this type of thing works great for
me:
<form onsubmit="return somefunction()">
where somefunction returns false. But I'm trying to do some thing where
in some
script block, the function gets added:
form.attachEvent("onsubmit", function () { return somefunction()
});
(not worrying about crossplatformosity, sorry). But that doesn't work,
the form is always submitted. Is there something else I need to be
doing to make this happen?

I have the following form working with on onsumbit function, but I would like to change it so that instead of having to click the purchase button to see total price, you only have to change the quantity text box input. I just can not seem to get it to work.
<script language="javascript" type="text/javascript">
function checkQuantity(frm) {
var succesful = false;
var numQuantity;
numQuantity = parseInt(frm.Quantity.value);
var numTotalPrice;
if (numQuantity != 0) {
numTotalPrice = numQuantity * 4;
frm.TotalPrice.value = numTotalPrice; //new String(numTotalPrice);
successful = true;
} else {
alert("Sorry must order more than 0");
successful = false;
} return succesful;
}
</script>
<form action="" onsubmit="return checkQuantity(this)" style="width: 193px">
<table cellpadding="4" style="width:111%">
<tr><td class="style1">
Quantity:</td><td class="formInputCell">
<input name="Quantity" type="text" style="width: 55px" /></td>
</tr><tr><td class="style1">
Total Price $
</td><td class="formInputCell">
<input name="TotalPrice" type="text" style="width: 55px" /></td>
</tr><tr><td class="style2"></td>
<td><input id="Submit1" type="submit"
value="Buy Now" class="buttonstyle" /></td>
</tr>
</table>

I am wondering if it is possible for me to replace my form submit button with an animated gif (fake progress bar), after the button has been pressed.Having so far disabled the button onclick, I would instead be happy if I could simply change the button text from 'Click here to submit' to 'Processing...'I have done some searches here but I'm finding references to innerHTML, etc., and I'm getting lost now.

I want to load an image with JS within the form event "onsubmit" without stipping the submit action of the form.
What I do is the following:
var img = new Image();
img.onload = function(){
myfunction();
};
[Code]....
This logic is a MUST for me, I mean I don't want to use settimeout to postpone the form submit, and I have to call the URL_FOR_PHP_SCRIPT_TO_DO_SOME_LOGIC this way since this code is on a JS file from different domain. This logic works fine on all browsers, and the request to call the image is sent -which is what exactly I need-, however on safari it doesn't call the image request, and start posting the form directly. I tried to add an "onunload" event on the page containing the form when the browsers is safari, but this didn't help too, and the form still submitting data directly without starting sending the request to load the image.

I am using ASP to dynamically generate a series of forms. When the
page is loaded, everything appears to be correct, except that the
first form generated fails with a "FormName is Null or not an Object"
error. Each subsuquent form created by the code after that works
perfectly. Why is it that the first form, generated with exactly the
same block of code, fails? Code:

I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax.
I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income.
<script language="javascript" type="text/javascript">
function TotalGrossPerYear() {
var Calc = document.NetIncome;
if (Calc.InputRad[0].checked) {

I've got some strange behavior with validation. I'm loading up a form to allow editing of an existing database entry. If I make my changes to the fields, enter in the required "revision comments" and submit, the page does NOT post, it seems to only refresh and empty out all the entries in each of the fields. Now, on the other hand if I open the form to make changes to a database entry and immediately press "Submit" without filling in the revision comments field, it fails validation and tells me to enter comments. Now if I fill in comments to satisfy all the requirements and press submit, it posts and I get my "Successful Entry" confirmation prompt. I think I've narrowed it down to the remote: part of my jQuery. I eliminated by trial-and-error the other pieces of the jQuery code and it seems that when I remove the remote: it does not experience this strange behviour.
jQuery Code:

// Form Validation customization
$("#Form_business").validate({
rules: {

I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.

If my php variable, (which is retrieved from a mysql table in the php code, not shown) is equal to "1", that means the member is not eligible to submit the form, so I want an alert() to say "member not eligible!". Else, I want it to continue to submit the form. Here is my code (which I can't seem to get to work):

<script src="js/jquery-1.4.2.js" type="text/javascript"></script>
//this first script is for something else, to check the max length of characters in a text area
