Question

I have some javascript code that looks like this:

dojo.query("#maintenanceOpData tr").forEach(function(node, index, nodelist){
    if (index % 2 == 0) {
        dojo.style(node, {
            "backgroundColor": "#FFFFCC"
        });
    };
});

Everything I find in online documentation shows that dojo.style expects the ID of the DOM element, not the DOM node itself. What can I do? The only other examples show using dojo.query(…).style(…), which applies the style to all nodes. I only want to apply it to every other node, which is why I use the for-each call.

Answer 1

Which version of Dojo are you using? Like JIP says, the code you’ve pasted should work fine ( http://jsfiddle.net/4HXMF/ ), given that you’re using a recent version of Dojo.

Dojo query actually supports many of the new selectors, so you can in fact do:

dojo.query("#maintenanceOpData tr:nth-child(odd)").style("backgroundColor", "#FFFFCC");
