JavaScript检测鼠标左右键点击动作，在第一个DIV里点击鼠标，可以测试出左、中、右鼠标键是否点击，并激活绑定的函数，这是一个JavaScript鼠标事件的示例程序，希望在以后的JS编程中会对您有所启发。
　　

<div id="mouse2" style="width:500px;height:200px;background:#E8FFE8;border:2px solid #336699;">
请在此点击，测试左、中、右鼠标键是否点击，并激活绑定函数

    var arg = arguments[0],
    el = arg.el || document,
    leftfn = arg.left || function(){},
