EyePulps solution works - but only partly. Because I need to change it after submitting back again, which doesn’t work for me. Im trying to do something like:

document.getElementById(’data’).encoding = “multipart/form-data”;
document.getElementById(’data’).enctype = “multipart/form-data”;
document.getElementById(’data’).submit();
document.getElementById(’data’).encoding = “x”;
document.getElementById(’data’).enctype = “”;

The first assignment works but after the submit() IE throws an error saying the property “encoding” does not exist. This browser really sucks…

Try the following:

var frame = document.createElement(’IFRAME’);
frame.name = frameName;
frame.id = frameName; // for MSIE fix later.
frame = body.appendChild( frame ); // appendChild() may return a different pointer..
window.frames[ frameName ].name = frameName;

This abuses the fact that window.frames[id] returns any element with an ID, not just frames. The frame exists in window.frames, but the name is not really registered yet in the DOM.

It seems my code didn’t come through fully. The following should have appeared inside the innerHTML single quotes:

If it still gets blocked this time, it’s simply an html iframe element with name and id explicitly set to be “mytarget”.

I was stuck with the same problem. The IE fix using “encoding” posted by EyePulp works great. As for his question about targeting a dynamic iFrame, I had that problem too. In the end, I check for IE and create my iframe in a div using an innerHTML. It’s the only way I have found that works.
iframediv = document.createElement( ‘div’ );
if (document.all)
iframediv.innerHTML = ”;
else {
myiframe = document.createElement( ‘iframe’ );
myiframe.id = “mytarget”;
myiframe.name = “mytarget”;
iframediv.appendChild(myiframe);
}

I found out how to change the enctype in ie dynamically - formObj.encoding = “multipart/form-data”;

set both .encoding and .enctype and it seems to work - however, I’m trying point it at a dynamic iFrame, and IE just isn’t accepting the .target value.

*sigh*

You might get away with copying the childNodes of that form into an array, creating a new form with the desired enctype, then removing the old form, replacing it with the new one, then appending the original childNodes. Then again, you may just be screwed.

I’m stuck with this problem too - how do you change enctype using javascript in IE6 for a form that already exists? (Using createElement is not possible). Any help greatly appreciated. You can change enctype no problem in Mozilla but IE6 barfs as you say.
