Tinymce jQuery.Validation generated BUG_jquery

The error location is around line 92 of jquery.metadata.js:

Copy code The code is as follows:

else if ( elem.getAttribute != undefined ) { // This line reports an error
var attr = elem.getAttribute( settings.name );
if ( attr ) data = attr;
}

The strange thing is that elem is a textarea object, but there is no getAttribute method
Solution: Try to modify it to the following code, and it succeeds

Copy code The code is as follows:

else {
data = $(elem).attr(settings.name);
}

There is a problem with IE6 Tinymce3.3 jQuery.validation jQuery.metadata
There is no problem with Firefox, and there is no problem with the Tinymce editor simple theme.
I have wasted 1 hour and have no time to study. .
