给html元素循环绑定事件

/**
 * 添加点击的样式
 */
function addClickClass(){
    var eles = ["a.province",".citys"];
    var classes = ["hover","hover2"];
    for (var i = 0; i < eles.length; i++) {
        var obj = new addClickClass_(i,eles,classes);
        $(eles[i]).bind("click",obj.clickFunc);
    }
}
function addClickClass_(idx,eles,classes) {
    this.clickFunc = function(event) {
        event = event ? event : window.event;
        var obj = event.srcElement ? event.srcElement : event.target;
        $(eles[idx]).removeClass(classes[idx]);
        $(obj).addClass(classes[idx]);
    }   
}

这里是实现了一个改变样式的功能。
