//使用示例
//WaitUntil(function(){return typeof jQuery !=="undefined" && $(".test").length>0}, function(){
//    alert($(".test").html());
//});

//其他参数
//cond 满足条件的函数
//callback 条件满足后执行的回调函数
//interval 监听满足条件的时间间隔,单位毫秒,默认100
//trys 尝试次数,超过这个数值就停止监听,默认为300(因默认间隔是100毫秒,所以默认停止监控时间为300*100毫秒,即30秒)
//times 执行次数,默认执行1次,-1为无限次,0会忽略,等同于1次
