[jQuery] cannot insert html into DIV

[jQuery] cannot insert html into DIV

Hi Guys,
I have several .class DIVs I want to manipulate. I have retrieved them
using the following code:
    var canvasClasses = new Array();
    $(".canvas").each(function() {
        canvasClasses.push()
    });
I am now trying to insert some HTML into the DIVs but its not working:
canvasClasses[0].innerHTML = "htmlhere";
Any ideas on why its not working ?
