在本文中用JQuery对class属性的操作方法实现页面中的按钮开关效果。
首先定义两个class:

.controlOff{
display:inline-block;
width:130px;
height:36px;
cursor:pointer;
background-image:url(“../iclass/images/teach_off.png”);
background-repeat: no-repeat;
}
.controlOn{
display:inline-block;
width:130px;
height:36px;
cursor:pointer;
background-image:url(“../iclass/images/teach_on.png”);
background-repeat: no-repeat;
}

再定义一个超链接标签:

<a href=’javascript:void(0)’ id=’teachControl’ class=’controlOff’></a>

接着写JS脚本完成切换效果:

function switchTeachControl(){
var target = $(“#teachControl”);
if(target.hasClass(“controlOff”)){
target.removeClass(“controlOff”);
target.addClass(“controlOn”);
}else{
target.removeClass(“controlOn”);
target.addClass(“controlOff”);
}
}
