Actually I thought on the solution you suggested, but I really don't like to call the "setup" method each time a new element is created, especially when there are a lot of HTML elements in the document that need to be parsed (I imagine a large tree, dynamic, with 2000-3000 nodes, each node having a context menu assigned). I'm thinking on another solution: creating a single element in the document, hidden, standard assigning the context menu using "setup" and, for all dynamic created elements of that type, treat "oncontextmenu" and "onclick" handlers through the similar handlers in the hidden element: <!-- triggerCtxMenu = function(e, someInfo) { //do something with "someInfo" like storing it in a global variable for further reference getElementById("myhiddenelement").onclick(e); } <mydynamicelement onclick="triggerCtxMenu(event, 'some info about the element');" > --> What do you think about it?
