本文实例讲述了基于jQuery创建鼠标悬停效果的方法。分享给大家供大家参考。具体实现方法如下:

1. 创建HTML:

<ul>
<li><a href="/tv"><img  src="images/tv_off.gif" class="mainnav" alt="基于jQuery创建鼠标悬停效果的方法_jquery" ></a></li>
</ul>

2. 选择.mainnav的class:

$(".mainnav").hover(
 function () {
 },
 function () {
 }
);

3. 建立变量imgPath,指定图片SRC:

$(".mainnav").hover(
 function () {
  // Grab the source
  var imgPath = $(this).attr("src");
 },
 function () {
  // Grab the source
  var imgPath = $(this).attr("src");
  }
);

4. 找到字符串off,用on替换:

$(".mainnav").hover(
 function () {
  // Grab the source
  var imgPath = $(this).attr("src");
  // Replace the path in the source
  $(this).attr("src",imgPath.replace("off", "on"));
 },
 function () {
  // Grab the source
  var imgPath = $(this).attr("src");
  // Replace the path in the source
  $(this).attr("src",imgPath.replace("on", "off"));
  }
);

希望本文所述对大家的jQuery程序设计有所帮助。
