Question

How do I detect if a table exists (which doesn't have a class or ID)

Answer 1

+1 A:

I suspect that you're not calling your function when the DOM is ready. Try:

$(document).ready(function() {
    if($('table').length) {
        alert('hello');
    }
});

Answer 2

A:

This seems to work for me:

<html>

<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"&gt;&lt;/script&gt;
<script type="text/javascript">
    $(document).ready(function() {
        alert($('table').length);
    });
</script>
</head>

<body>
<table></table>
<table></table>
</body>

</html>

Answer 3

A:

If you are calling the element before it exists, it will not work.

You can:

Insert the script after the element
Make the script execute when the page is ready

See this example

Answer 4

A:

Firstly. Holy crap! I can’t get over how quick my question was answered.

@BrunoLM: The table is being generated by CFML code in our CMS. One of the pages having a problem is the search page (which will be fixed in another few minutes thanks to everyone who has replied). I don’t have an example page as it’s on a development server behind our firewall.

@Felix Kling: The code was in the bottom of the header.

@Everyone: Wrapping the check with $(document).ready(function() {}); has fixed the problem (thank you).
