How do I manipulate an external list view's columns with javascript?

Question

I want to manipulate the columns of an external list view (XsltListViewWebPart), however, as the data loads asynchronously I must wait for the data to load and the table to be generated before my code can run.

I assume I need to use a callback but can't find anything.

Answer 1

I ended up just polling for the existence of the table containing the data, which will have class ms-listviewtable. (I'm using jQuery here.)

$(function(){
    var intervalId = setInterval(function() {
        if ($('.ms-listviewtable').length > 0) {
            clearInterval(intervalId);
            // Code here
        }
    }, 100);
});
