jquery 函数如何更改为dom 函数?

<script type="text/javascript">
$(
function()
{
var onSampleResized = function(e)
{
var columns = $(e.currentTarget).find("th");
};

$("#sample2").colResizable({
liveDrag:true, 
gripInnerHtml:"<div class='grip'></div>", 
draggingClass:"dragging", 
onResize:onSampleResized});

}
);
</script>

jquery 初学，如何上面这个函数改成dom
[解决办法]
如果你非要改，那只能改成这样：

window.onload = function(){
    var onSampleResized = function (e) {
        var columns = $(e.currentTarget).find("th");
    };

    $("#sample2").colResizable({
        liveDrag:true,
        gripInnerHtml:"<div class='grip'></div>",
        draggingClass:"dragging",
        onResize:onSampleResized
    });
}
