hi, I have got a simple way to make "textarea" support "auto-submit"
when pressing Ctrl+Enter, and tested under both IE and Firefox.

The common old method is like this:
<form name=form2>
<textarea onkeydown='if(event.keyCode==13 && event.ctrlKey) return
document.form2.submit()'>
</textarea>
</form>

It is not good, because:
1) must give the FORM a name or id.
2) when the "name" of FORM changed, must change the code
3) worst is I must input(or copy) the code.....

I tried a simple way to do this boring thing, and only need input code
once.
1) write a js file, e.g. common.js
/*
* auto support Ctrl+Enter to submit form
* by Net@lilybbs (yuelinniao@hotmail)
*/
window.onload = function()
{
for(var i=0; i < document.forms.length; i++)
{
var frm = document.forms[i];
for(var j=0; j < frm.length; j++)
{
var e = frm.elements[j];
if(!e.type)
continue;
if(e.type=="textarea")
e.onkeydown = function(evt)
{
evt=(evt)?evt(event)?event:null);
if(evt.ctrlKey && evt.keyCode==13)
{
this.form.submit();
return false;
}
}
}
}
}

2) when import, the page's textarea(s) support Ctrl+Enter to submit
form
<script type="text/javascript" src="common.js"></script>

hope help someone. Sorry for my poor English.

I don't like "window.onload", I always insert such codes at the end of
the page, just before the </body>, there's a defer property for the
<script> tag, but it doesn't seem to work right =|

Since you're offering this to the community, you should assign your
handler using any "addEvent function", to avoid overwriting the user event.

That's not my language too

The created onkeydown function will execute in the context of the input
element. So try "this.form.submit()" instead of "document.form2.submit()"
