running against a class results in "Element must be a table" error

[adam-jones-net]

I am initialising the plugin with

new Tablesort(document.getElementsByClassName('trackTable'), {
    descending: true
});

on a table that starts:

<table id="mySearchesTable" class="trackTable noSelect" cellpadding="0" cellspacing="0">

Yet I get the following error:

Uncaught Error: Element must be a table

[tripu]

Document.getElementById(), which is the usual way of picking the table element, returns a scalar (an Element), while Document.getElementsByClassName() returns a vector (an HTMLCollection).

If you're sure you have just one element with that class, try something like:

document.getElementsByClassName('trackTable')[0]

But it's much better if you pick the element by its ID!

(Please confirm that's the issue you're having, so I can close this :)
