jQuery自定义多选下拉框效果

$(".dropdown-opt button.ok").click(function(){
toggleDrop();
okFn&&okFn.apply(this,[parm]);
});

//Cancel button event
$(".dropdown-opt button.cancel").click(function(){

toggleDrop();
cancelFn&&cancelFn.call(this);
});
};

$.fn[_pluginName] = function (options,okFn,cancelFn) {

var options = $.extend(defaults, options);
return this.each(function () {

init(this,options,okFn,cancelFn);
});
}
})(jQuery,window,document);

6.不足

　　页面样式在不支持css3浏览器中显示有问题 后期需要改进

     下拉数据为一次性渲染 如有需要 可设置滚动加载

     下拉框滚动条的美化未兼容所有浏览器

      搜索时检索数据直接源自页面数据 所有需要添加延迟处理 获取服务端数据
