Versions below IE7 have not supported pseudo-classes without A status, and usually rely on Javascript to solve this problem. Recently, people often ask about this kind of problem, so I have compiled several methods. The scripts are from foreign websites for your reference.
Method 1
javascript file, from Htmldog.
function suckerfish(type, tag, parentId) {
if (window.attachEvent) {
window.attachEvent("onload", function() {
var sfEls = (parentId== null)?document.getElementsByTagName(tag):document.getElementById(parentId).getElementsByTagName(tag); sfHover = function(sfEls) {
for (var i=0; i sfEls[i].onmouseover=function() {
this.className+=" sfhover" ;
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" sfhover\b"), "");
}
}
}
sfFocus = function(sfEls) {
for (var i=0; i sfEls[i].onfocus= function() {
this.className+=" sffocus";
} }
sfEls[i].onblur=function() {
this.className=this.className.replace(new RegExp(" sffocus\b"), "");
🎜>suckerfish(sfHover, "p");
The changeable part of the script
//Write the tag you need the effect here
suckerfish(sfHover , "INPUT");
suckerfish(sfFocus, "INPUT");
suckerfish(sfHover, "p");
CSS
input:focus,input.sffocus {
background: #F8F8F8;
color: #333333;
border: 1px solid red;
}
input:hover,input.sfhover{
background: #E EE;
color: #369;
border: 1px solid #069;
}
p:hover,p.sfhover{
background: #EEE; > border: 1px solid #069;
}
p:hover,p.sfhover{
background: #EEE;
color: #333;
}
above The first class in the code is for browsers that support CSS2, and the second one is for IE6 and below. It should be noted that if you set a certain tag, the tag in the entire page will use the same style.
Method 2
javascript file.
Copy code
The code is as follows:
var W3CDOM = (document.createElement && document.getElementsByTagName);
//window.onload = pinballEffect;
function pinballEffect()
{
if (!W3CDOM) return;
var allElements = document.getElementsByTagName('*');
var originalBackgrounds=new Array();
for (var i=0; i
{
if (allElements[i].className.indexOf('hovereffect') !=-1)
{
allElements[i].onmouseover = mouseGoesOver;
allElements[i].onmouseout = mouseGoesOut;
}
}
}
function mouseGoesOver()
{
originalClassNameString = this.className;
this.className += " lay-on";
}
function mouseGoesOut()
{
this.className = originalClassNameString;
}
pinballEffect();
脚本可改动的部分
1. if (allElements[i].className.indexOf('hovereffect') !=-1)
CSS
1. .hovereffect{
2. Background: #CCC;
3. }
在需要应用效果的地方用class="hovereffect"调用。这种方法比较灵活。
方法三
使用网上常见的onmouseover、onmouseout这类东西,行为和结构不分离,不推荐使用。
