Why In Firefox It Is Ok, But In Ie8 It Print 'undefined Undefined'?
Since you're using jQuery (I see you have $('p#vtip').show(); in there), you might as well use jQuery to bind the events, too. jQuery will also normalize the way you can access the event attributes across browsers when you use it to bind the events instead of the inline events you're using now.
See the jQuery event docs.
Here's an example of how to set up the html differently. Give the spans a class and remove the onmouseover.
<spanclass='tipped'>程序错误<divclass="content">good</div></span><br>Assign the mouseover event to the spans with jQuery.
<script>
$('.tipped').mouseover(function(evt){
$('p#vtip').show();
xOffset = -10; // x distance from mouse
yOffset = 10; // y distance from mouse alert(evt.pageY+' '+evt.pageX)//this should work fine in IE too, since it's a jQuerified event object
});
</script>Solution 2:
IE doesn't support event.pageY/event.pageX. Use event.clientX, event.offsetX or event.x
Solution 3:
IE uses clientX / clientY, not pageX / pageY.
Solution 4:
Actually, there is a bug in VTip, I just haven't found exactly where it is because it's not 100% reproducable. I can reproduce it about 50% of the time. I also get the "undefined" on the tip text, but it's not in the html! jQuery/vtip is producing/showing the "undefined" text. If I do a View Source on the actual output, the expected text is there in the title tag content, but if I mouseover it, it shows "undefined". If I reload the page, it works correctly. So, there's definitely a bug. Also, it's not any certain row on the page that causes the "undefined". It appears to be random, and it's always just one row.
Very strange. Still searching to see who has fixed this bug.
