javascript - 如何使用GreaseMonkey关闭定时弹出的窗口？

问题描述

问 题

在某网站观看视频时，每隔一段时间会弹出一个问题，回答后才能继续观看，希望可以使用GreaseMonkey自动回答弹出的问题。
弹窗使用jQuery1.4.4的dialog弹出，弹出后可以使用下面的代码选择正确的答案。

document.querySelector('[qs=True]').click()
document.querySelector('#but_Question').click()

尝试使用

// ==UserScript==
// @name        test_auto_close_dialog
// @namespace 
// @include     http://zjxy.ghlearning.com/Study/Learning/MediaLi?sscId=8f658a796db74a3ea9dde99e5a571534&medId=e4975f7a1a4e42768902bf35af23868c
// @version     1
// @grant       none
// ==/UserScript==

$('.ui_main').bind('dialogopen',function(event){
   document.querySelector('[qs=True]').click();
  document.querySelector('#but_Question').click();
})

绑定弹出事件，但是没有取得预期的效果。请问是否有办法写一个脚本，以自动回答问题？

其中关于播放器的代码如下：

var LiPlayerPlayState = {};
LiPlayerPlayState.Stopped = 1;
LiPlayerPlayState.Paused = 2;
LiPlayerPlayState.Playing = 3;
LiPlayerPlayState.Ended = 8;
LiPlayerPlayState.Ready = 10;
LiPlayerPlayState.Reconnecting = 11;
var playerVideo = null;

var LiPlayer = function (containerId, _config) {
    //针对800里流媒体播放学习
    this.containerId = containerId;

    this.config = {
        onLoad: function () { },
        onStoped: function () { },
        onPaused: function () { },

        onBuffering: function () { },
        onBuffered: function () { },
        onPositionChange: function (o, n) { },
        onEnded: function () { },
        onLoadError: function (message) { },
        onLoadOverPlay: function () { },
        width: "100%",
        height: "100%",
        resPath: "",
        playerURL: "",
        playSite: "",
        playQuery: ""
    };

    $.extend(this.config, _config);
    if (this.config.width != "100%") {
        this.config.width += "px";
    }
    if (this.config.height != "100%") {
        this.config.height += "px";
    }

    p2psr_embed("auto", "vod", this.config.playSite, this.config.playQuery, "p2ps_video", this.config.width, this.config.height, "10.1.0",
        this.config.resPath + '/Files/expressInstall.swf', { auto_play: 1, no_light: 1, no_side_bar: 1, no_hide_skin: 1 }, { allowFullScreen: true, allowScriptAccess: "always", wmode: "transparent" }, {}, swfPlayerInit);

解决方案

自己解决了
只需要定时完成一系列操作就行

    setInterval(function(){
      try{
         document.querySelector('[qs=True]').click();
         document.querySelector('#but_Question').click();
      }
      catch(e){
        if (window.console){
          window.console.log("Error in this userscript");
        }
      }
    }, 100000);
