[jQuery] Jquery Function Not Working In Opera
in Using jQuery
•
13 years ago
I have the following code:
<code><pre>var depth = 2;
var name = 'category' + depth;
var html = $('<div class="indent">'
+ "\n<p>\n" +
'<label for="' + name + '">Sub
Category:</label> ' +
'<select id="' + name + '"
name="' + name + '">' + "\n" +
'<option value="none">Select a
sub category</option>' + "\n" +
'<option value="0">Add new sub
category</option>' + "\n" +
"</select>\n</p>\n</div>
\n");
alert($(html).children('p')[0].nodeName);</pre></
code>
In FF, IE7 and Safari it will alert 'p', but in Opera (tested 9.64 and
10Alpha1) I just get an error in the Error Console:
<code><pre>JavaScript - http://photosite.com/upload

stacktrace: n/a; see 'opera:config#UserPrefs|Exceptions Have
Stacktrace'</pre></code>
If I run the code in the Command Line in Opera Dragonfly it just gives
the error:
<code>Cannot convert undefined or null to Object</code>
Can anyone help me with this? (I couldn't find any info on if this
message will be encoded as html or plain text, but in the event it
comes out as plain text, you can see the code snippets here:

Thanks
