如何获得对dojo.xhrPost加载内的点火dom节点的访问？

Question

I have an html fragment like the following:

<li>
    <img src="/jsafe/gallery/item/83/thumb" />
    <span class="tools">
        <a href="/jsafe/gallery/item/83/rotate/left">
            <img src="/jsafe/img/rotate_left_small.png" alt="Rotate Left"/>
        </a>

        <a href="/jsafe/gallery/item/83/rotate/right">
            <img src="/jsafe/img/rotate_right_small.png" alt="Rotate Right"/>
        </a>
    </span>
</li>

I have a dojo fragment like the following:

dojo.query(".tools a:nth-child(1)").forEach(function(node,index,arr){
    dojo.connect(node, "onclick", null, function(e){
        e.preventDefault();
        dojo.xhrPost({
            url: dojo.attr(e.currentTarget, "href"),
            handleAs: "json",
            load: function(data) {
                //TODO
            }
            },
            error: function(error) {
                var u = "";
            }
        });
    })
});

Inside the load function how can I get to the e.currentTarget dom node? I know load is a separate callback function but I need to get to that dom node to do more manipulation.

Did you try just referring to e.currentTarget from within the load function? :)

Since your load function is defined within the event handler function which has access to e , you still have access to it.
