Javascript submit() event is not fired up on exit (unload event)
I got page where HTML elements <form>
and <iframe>
are dynamically created with Javascript:
document.write('<iframe id="myIframe" name="myIframe" src="about:blank" style="display:none;"></iframe>');
document.write('<form id="myForm" name="myForm" method="post" target="myIframe" action="myURL.php" style="display:none;">');
document.write('<textarea name="d"></textarea>');
document.write('</form>');
Then some data is placed into <textarea>
element and submitted:
var data = '';
function myOnClick()
{
// combine data
data += 'click|';
if (data.length > 17)
{
// initiate after 3rd click
mySubmit();
}
};
function myOnUnload()
{
if (data.length > 0)
{
mySubmit();
}
};
function mySubmit()
{
var form = document.getElementById('myForm');
var textarea = form.getElementsByTagName('textarea')[0];
// set data
textarea.innerHTML = data;
// send data
form.submit();
// set var to default value
data = '';
};
if (document.addEventListener)
{
// Gecko browsers
document.addEventListener('mousedown', myOnClick, false);
}
else if (document.attachEvent)
{
// IE browsers
document.attachEvent('onmousedown', myOnClick, false);
}
window.onunload = function()
{
myOnUnload();
};
The problem is that clicking on the page data
is combined and sent as it supposed to do on both Gecko and IE browsers in the same way. But when user is leaving the page and the data
is set form.submit()
is not initiated on Gecko browser though IE does it as I wanted to do.
For example, on the same page exists link <a href="http://www.google.com">Google</a>
which user submits after he/she clicked anywhere on the page. Once user done that, data
is set and need to be submited to myURL.php
, but it's not.
UPDATE: This is the whole code http://pastebin.com/DF3DVLpG. By mentioning Gecko based browsers I had in mind other popular browsers such as Firefox, Opera, Chrome and Safari. Sorry for misleading.
What could be the problem: Javascript code, browser behaviour or something e开发者_如何学编程lse?

Not sure if that is your exact problem without seeing more of your code. If that is all of your code, it is very likely that is the problem.
I got it working by using other event - onbeforunload.
