onclick

问题 As above, I have a button that, when clicked, will open the sub-menu. For each option in the sub-menu there are three elements (there's actually more I think, but will keep it as 3 for simplicity). I give focus to the main div (white 'frame') of the sub-menu. Onblur of this div - I then hide the sub-menu. This all behaves as expected - but I have the probem that when one of the 3 elements for a particular option are clicked (i.e. given focus), the main div will close due to it's onblur event

问题 I have a bunch of links that use a target="_blank" attribute to open in a new window. I want to attach Google Analytics goal tracking to clicks of these links. To do this, I tried attaching an onclick="pageTracker._trackPageview('/event/outgoing')" attribute to the links. But I discovered that for links with a target="_blank" attribute, the Javascript onclick event gets skipped. So the goal is not recorded. In other words, this link successfully records the goal: <a href="http://www.yahoo.com

问题 I am using jQuery to dynamically (I mean at runtime) add a span element to my page's DOM: // create add task button $(document.createElement("span")) .attr({ id: activityNameHyphened + "-NewButton", name: activityNameHyphened + "-NewButton" }) .addClass("smallButton") .appendTo(cell1) .click(CreateTaskRow(ActivityName)); The problem is the last line: I thought it would add CreateTaskRow(ActivityName) as the handler for the onclick event of the span, just like: <span onclick="CreateTaskRow
