mouseover

问题 When using : document.onmouseover = function(e) {} Is there a property which gives me the element in the dom tree ? For example, I can set a style to e.srcElement But, how can I later access this element to (for example) reset its style ? And how can I know at which place in the dom tree it is ? I want to be able to situate it in the whole page dump. Many thanks. To solve the problem about reaccessing the element later, I tried this but it doesn't work : var lastelem; document.onmouseover =

问题 Is there a way to detect from which side of a div the mouse cursor came from? Currently i'm using this method: jQuery(this).bind('mousemove',function(e){ offset_pos_x = parseInt(e.offsetX); offset_pos_y = parseInt(e.offsetY); ... Then i look for the distances the mouse went inside the div, in which direction. The Problem is, this method is a bit buggy because i need all 4 sides, not just two, so i have to check offsetX AND offsetY. If i move the mouse inside the div for example X:+15,Y:-3 (in

问题 I'm trying to add tooltips for the nodes of a Tree in GWT. As such, I'd like to add a mouseover listener for the nodes of a tree rather than on the tree itself. The Treelistener interface seems to be what I want but this is now deprecated in lieu of the handler system. I don't quite understand how to get mouseover behaviour on the cell as I only seem to be able to add a MouseOverHandler to the tree itself. Any help would be appreciated, thank you. 回答1: A TreeItem can contains a Widget object.

问题 404 Page or 500 Page Anyone have any idea how to do this sort of thing? The animation that moves with your mouse? Thanks for the correction, @Alin. Just a link to a tutorial would be nice. EDIT: Just also learned it's the parallax effect. That should help. 回答1: The effect is accomplished with javascript, not just CSS. The source code is on the page you linked to. Have a look at jParallax, which makes it easy to implement the effect in a robust way on your own site: http://stephband.info

问题 I have noticed a weird performance thing in IE8 when using mouseover events on a table with many rows (100 in this example). I have tried a lot of different approaches but I can't seem to find any way to get it as fast as I like/need. If I switch classes on each event the performance goes down in all IE versions, and If I use direct manipulation of the CSS through javascript IE6 and IE7 speeds up alot, but IE8 still performs lousy. Any ideas ? I would really like to know what it is that makes

问题 No listeners involved. The thing is, I can use MOUSE_OVER and MOUSE_OUT listeners, but if you drag a mouse over a MovieClip quickly enough, one of these listeners may not be activated. I've tried it several times. 回答1: If the mouse passed by "quickly enough" then maybe the OS didn't send any mouse events to Flash for that portion of the screen, in the first place. Moving the mouse a lot faster than its resolution can fire (or the OS can handle) will have the effect you are witnessing (and the

问题 I'm trying to look for an example of code that allows the user to animate a gif on mouseover and pause when mouse out. I've seen many tutorials talking about this but I want a different effect. I noticed that most gifs "reset" when on mouse out. That is, either the gif is covered with a generic image or the animation reverts back to the start. What I would like to achieve is a more seamless "pause" that allows you to start where you left off without using a placeholder image. Similar to the

问题 I am having some issues with jQuery MouseOut and MouseOver. Every time I hover over the selected div, the child div that needs to show appears. however, it starts flashing. I have no idea why. I have posted the code up on JsFiddle. http://jsfiddle.net/Dn6Rq/ Here is the HTML code: <div class="section-item-portal"> <div class="section-text">Lorem Ipsum Dolor Sit Amet, Lorem Ipsum Dolor Sit Amet, Lorem Ipsum Dolor Sit Amet, Lorem Ipsum Dolor Sit Amet, Lorem Ipsum Dolor Sit Amet, Lorem Ipsum
