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

//其他参数
//condfunc 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
