How do I obtain an anchor's attribute value via javascript

Ok, so I've got an ASP.NET TreeView Control which I have all wired up to catch a client-side click event.  Now I want to figure out the Value of the clicked node.

My nodes are rendering as (simplified):
<td>
        <input type="checkbox" name="myCheckBox" id="myCheckBox" />
        <a href="javascript:__doPostBack('someName','s283\\289')>
                The Node Name
        </a>
</td>

I've obtained a reference to the specific node via:
function TreeViewOnClick() {
            var item = window.event.srcElement;
            if(item.tagName == 'INPUT' && item.type == 'checkbox') {
                    // a checkbox has been clicked
                    // now get the value from the corresponding anchor tag
                    // ...Here...
            }
}

What I want is the "289" from the href in the <a> of the <td>.  I understand I'll have to use a substring to get the specific "289" I want, however how do I get a reference to the corresponding anchor from the input reference I already have from 'window.event.srcElement;'?

Try using the element's nextSibling property

function TreeViewOnClick() {
            var item = window.event.srcElement;
            if(item.tagName == 'INPUT' && item.type == 'checkbox') {
                    // a checkbox has been clicked
                    // now get the value from the corresponding anchor tag
                    // ...Here...
                    var hrefProp = item.nextSibling.getAttribute("href");
            }
}

Keep in mind that you may end up getting returned a text node and will need to check for this.

I suggest (since href="javascript:..." will render the browser unstable

this:

      <a href="#" id="'someName" title="s283\\289" onClick="__doPostBack(this.id,this.title)" >
                The Node Name
        </a>

then you can do
var title = theCheck.parentNode.getElementsByTagName('a')[0].title

That worked perfectly.  I knew it was simple, just couldn't figure it out.
