jquery的拖放问题，麻烦大神帮我看看
jquery代码：
$.each($(".drawImg"),function(){
this.draggable({
start: function(event, ui) {
},
stop: function(event, ui) {
}
});
});


html代码：
<div id="drawImgArea" class="drawImgAreaBac">
<div id="Linecontainer-$tab_idx" class="drawImg">
</div>
<div id="Circlecontainer-$tab_idx" class="drawImg">
</div>
<div id="Rectcontainer-$tab_idx" class="drawImg">
</div>
<div id="Polygoncontainer-$tab_idx" class="drawImg">
</div>
</div>


怎么拖不了呢，代码哪里写的不对吗？

------解决方案--------------------

JScript code

    $.each($(".drawImg"), function () {
        $(this).draggable({/////
            start: function (event, ui) {
            },
            stop: function (event, ui) {
            }
        });
    });
