Change background color on mouseover and remove it after mouseout

由 ぃ、小莉子 提交于 2019-11-27 20:05:06
I have table which class is forum . My jquery code: <script type="text/javascript"> $(document).ready(function() { $('.forum').bind("mouseover", function(){ var color = $(this).css("background-color"); $(this).css("background", "#380606"); $(this).bind("mouseout", function(){ $(this).css("background", color); }) }) }) </script> It perfectly works, but is it possible to do it in more efficient way without var color = $(this).css("background-color"); . Just after mouseout leave the previous background-color and remove #380606 ? Thank you. If you don't care about IE ≤6, you could use pure CSS ...

How to show hidden divs on mouseover?

How to show a set of hidden div's onmouseover? For example : <div id="div1">Div 1 Content</div> <div id="div2">Div 2 Content</div> <div id="div3">Div 3 Content</div> All div's need to be shown onmouseover event. If the divs are hidden, they will never trigger the mouseover event. You will have to listen to the event of some other unhidden element. You can consider wrapping your hidden divs into container divs that remain visible, and then act on the mouseover event of these containers. <div style="width: 80px; height: 20px; background-color: red;" onmouseover="document.getElementById('div1')

Simulate Mouse Over in Vimperator plugin

由 梦想的初衷 提交于 2019-11-27 12:23:42
I'm attempting to write a Vimperator plugin to allow use of hints mode to simulate mouse over on drop down menus. I have the hints mode working and can correctly choose elements that have mouseover events attached. The problem is my function to simulate the mouse over is not working.

问题 I've got a simple html/css page, where I show a picture. Now when the user moves the mouse on the picture, I'd like to swap out the picture to some other image. Upon leaving the image area the old picture should be shown again. How can I achieve this? A version which works without javascript would be best. Thanks in advance! 回答1: You can use CSS to change the background image of an element when you hover over it. The hover pseudo-class is supported on most elements in recent browsers, but to
