‘叁’ html怎么实现当鼠标经过一个图片时显示另一张图片

1、准备切换图片素材，一般是两张，如图，放入img文件夹，跟HTML同级。

</ul>

</li>

</ul>

</li>

</ul>

</div>

2、css代码：

ul.menu > li > a{

float:left;

width:265px;

height:50px;

margin-top:450px;

text-align:center;

line-height:50px;

color:#ddd;

background-color:#333;

letter-spacing:1px;

cursor:pointer;

text-decoration:none;

text-shadow:0px 0px 1px #fff;

}

ul.menu > li ul{

list-style:none;

float:left;

margin-top:-180px;

width:100%;

height:110px;

padding-top:20px;

background-repeat:no-repeat;

background-color:transparent;

}

ul.menu > li ul li{

display:none;

}

ul.menu > li ul.sub1 {

background-image: url('../img/bg1sub.png');

}

ul.menu > li ul.sub2 {

background-image: url('../img/bg2sub.png');

}

ul.menu > li ul.sub3{

background-image:url(../img/bg3sub.png);

}

ul.menu > li ul li a{

color:#fff;

text-decoration:none;

line-height:30px;

margin-left:20px;

text-shadow:1px 1px 1px #444;

font-size:11px;

}

ul.menu > li ul li a:hover{

border-bottom:1px dotted #fff;

}

ul.menu > li ul.sub1 li{

display:block;

}

3、js代码：

if (!document.defaultView || !document.defaultView.getComputedStyle) { // IE6-IE8

var oldCurCSS = jQuery.curCSS;

jQuery.curCSS = function (elem, name, force) {

if (name === 'background-position') {

name = 'backgroundPosition';

}

if (name !== 'backgroundPosition' || !elem.currentStyle || elem.currentStyle[name]) {

return oldCurCSS.apply(this, arguments);

}

var style = elem.style;

if (!force && style && style[name]) {

return style[name];

}

return oldCurCSS(elem, 'backgroundPositionX', force) + ' ' + oldCurCSS(elem, 'backgroundPositionY', force);

};

}

var oldAnim = $.fn.animate;

$.fn.animate = function (prop) {

if ('background-position' in prop) {

prop.backgroundPosition = prop['background-position'];

delete prop['background-position'];

}

if ('backgroundPosition' in prop) {

prop.backgroundPosition = '(' + prop.backgroundPosition;

}

return oldAnim.apply(this, arguments);

};

function toArray(strg) {

strg = strg.replace(/left|top/g, '0px');

strg = strg.replace(/right|bottom/g, '100%');

strg = strg.replace(/([0-9.]+)(s|)|$)/g, "$1px$2");

var res = strg.match(/(-?[0-9.]+)(px|\%|em|pt)s(-?[0-9.]+)(px|\%|em|pt)/);

return [parseFloat(res[1], 10), res[2], parseFloat(res[3], 10), res[4]];

}

4、实现效果

‘陆’ html怎样实现图片自动切换

1、首先，打开html编辑器，新建html文件，例如：index.html。

‘柒’ html5点击链接在框架内更换图片

你好这种效果很简单的采用jquery 然后假设另一张图片名叫 a.gif 并且和 depart_info_close.gif存放在同一个文件夹下给a标签新加一个属性 id="a" 然后按照你提供的高袭 html结构代码如戚谨兄下
$(function(){
$("#a").click(function(){
$(this).prev().attr({"src":"a.gif"});
});
})
这样子就好了
代码的晌拆意思是当点击a标签时寻找与他同级的并且在他之前的那一个元素也就是img标签
并且改变 img标签中的 src属性为 a.gif
希望能帮到你谢谢
