I'm having a strange issue with counting form elements in jQuery. While I can work around it, I w开发者_如何学Cas wondering if anyone knows why there is a difference between browsers with the following example?
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>IE Test</title>
<meta name="description" content="" />
<meta name="keywords" content="" />
<meta name="author" content="" />
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
alert($('form :input').length);
});
</script>
</head>
<body>
<div id='wrapper'>
<div id='header'>
<form action='#' method='POST'>
<input type='text' name='title' value='Hotdog Fanatic'></input>
</form>
</div>
</div>
</body>
IE 6/7/8 all give me a result of 2, while FF, chrome, opera and safari all count 1 matched element.
If I change the selector to filter by any attribute, the count appears correct. For example, form :input[name] or form :input[type] as the selector returns just one matched element in IE.
Does anyone know why this might be?
Thanks!
Baps.
Remove the </input> end tag.
Instead, you should make a self-closing tag:
<input type='text' name='title' value='Hotdog Fanatic' />
Change your script to
<script type="text/javascript">
$(document).ready(function(){
alert($('form :input')[1].outerHTML);
});
</script>
This will alert </INPUT>.
Input elements are not containers, when using XHTML strict, as you are, replace it with this:
<input type='text' name='title' value='Hotdog Fanatic' />
