    copied!<p>This example is simplified a bit, but in my ASP.NET web page in my c#/jquery code I am using a right hand context menu that displays ‘rightMenu’ when a right mouse is clicked.</p> <pre><code>$(document).ready(function() { $(".RH_signoffrow td").contextMenu({ menu: 'rightMenu' }, function(action, el, pos) { var mykey = getkeyforitem(el); mykey = "Details|" + mykey; alert( 'Action: ' + action + '\n\n' + 'Key is: ' + mykey ); if(action == "details"){ trigger_details_panel(mykey); } }); }; //for any td in the right hand side - get its row key function getkeyforitem(el){ var mykey = $(el).parent().find('.hiddenrowkey').text(); // alert( // 'Internal getkeyforitem Call' + '\n\n' + // 'Key is: ' + mykey // ); return mykey; }; </code></pre> <p>The callback of the menu passes back the element that was clicked, and that can be used to pull the keydata out of the current table row. Once I have that keydata, I can use it to call the real function I was after: trigger_details_panel(mykey).</p> <p>This works fine if I only want to use the right mouse, but I want to include an image in some of the rows, so that when the image is clicked, it produces the same effect,as the right mouse menu selection.</p> <p>I am not sure how to accomplish that cleanly.</p> <p>I can include an image that links to javascript in my page…</p> <pre><code> &lt;asp:ImageButton ID="imgDetails" runat="server" ToolTip="Show Details" ImageUrl="./images/details.gif" OnClientClick="showdetailsclicked();return false;"&gt;&lt;/asp:ImageButton&gt; </code></pre> <p>But how can I get it to call the code: </p> <pre><code>getkeyforitem(el); </code></pre> <p>Or at least know the element (el) it belongs to? It seems like there should be a way to use the (this) pointer to get at what I want - but I don't see it. Am I just missing a more straightforward way to accomplish the whole problem?</p>
