jQuery chokes on a page without doctype .dtd file reference
Hello everyone.
I have a little piece of jquery running... i found it chokes on IE.. IE always renders the "else"
Firefox and Chrome work perfect.
If you duplicate this code in 2 files and then put the doc type for one as
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
and the doc type for the second as
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
The rest of the file is the same.
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
</head>
<div id="rightFloat" style="width:200px;border:
HEY I Am Here!
</div>
<img src="justj.jpg" />
<script language="javascript">
if ($('img[src = "justj.jpg"]').length) {
//if the image with that src exists
document.getElementById('r
document.write("Yippeee.. I display block!")
} else {
document.getElementById('r
document.write("I am the else statement, I display none!")
}
</script>
</html>
You notice that in firefox and chrome - BOTH WORK and the condition pops up the div.
You'll notice in IE, that the one without the .dtd reference in the doc type does NOT WORK
If I can not change the doc type.. is there anything else to consider why IE would choke on this particular code snippet and not other instances of jquery?
