The following script throws the error
this.getElementsByTagName is not a function
using the current jquery release.
$("//tr").each(function(i) {
f = $("//td", this).text();
alert(f);
});
The problem appears to be in lines 869-880, where jQuery assumes that an
XPath expression that leads with "//" or "/" is always evaluated in a
document context rather than a node context.
// Handle the common XPath // expression
if ( !t.indexOf("//") ) {
context = context.documentElement;
t = t.substr(2,t.length);
// And the / root expression
} else if ( !t.indexOf("/") ) {
context = context.documentElement;
t = t.substr(1,t.length);
if ( t.indexOf("/") >= 1 )
t = t.substr(t.indexOf("/"),t.length);
}
"documentElement" is undefined for a DOM node. Do these blocks need to be
present? Is there a reason that the descendant axis should not be evaluated
in a node context?
--------------------------------
Cut-and-paste example:
<head>
<script type="text/javascript"
src="http://jquery.com/src/jquery-latest.pack.js";>
</script>
<script type="text/javascript">
$(document).ready(function() {
$("//tr").each(function(i) {
f = $("//td", this).text();
alert(f);
});
});
</script>
</head>
<body>
<table><tr><td>f1</td><td>f2</td></tr></table>
</body>
