The next source works under IE but not under Mozilla:
var requestForm;
function RequestPage(page) {
alert("menu clicked");
if(requestForm == null) {
requestForm = document.createElement('FORM');
alert("so far so good 1");
requestForm.setAttribute('name','myForm');
alert("so far so good 2");
requestForm.setAttribute('target','mainFrame');
alert("so far so good 3");
requestForm.setAttribute('method','POST');
alert("so far so good 3A")
document.appendChild(requestForm);
alert("so far so good 4");
}
requestForm.setAttribute('action',page);
alert("submit nu")
requestForm.submit();
}
After alert 3A everything stops while using Mozilla

What bothers me is that it all works under IE, I do not like IE and want my software to work under
any browser.

Reproducible: Always

Steps to Reproduce:
1.create javascipt to hidden call a form
2.create input button
3.click button
Actual Results:  
The next source works under IE but not under Mozilla:
var requestForm;
function RequestPage(page) {
alert("menu clicked");
if(requestForm == null) {
requestForm = document.createElement('FORM');
alert("so far so good 1");
requestForm.setAttribute('name','myForm');
alert("so far so good 2");
requestForm.setAttribute('target','mainFrame');
alert("so far so good 3");
requestForm.setAttribute('method','POST');
alert("so far so good 3A")
document.appendChild(requestForm);
alert("so far so good 4");
}
requestForm.setAttribute('action',page);
alert("submit nu")
requestForm.submit();

Expected Results:  
Nothing under Mozilla, but fine under IE (and I hate microsoft and want to convince my cLient Mozilla and open source is better)

Appending an element to a document is unlikely to work unless the document already doesnt contain any elements. A document can only have one direct child element. Maybe you mean to use document.body.appendChild or append the element to a more specific place in the document?

Sorry,

My mistake, I should have known you folks are better than Microsoft, I was only worried about my project.

Comment 4

[Dave Townsend [:mossop]]

The original code fails because of bug 118327 so this is a dupe
