c# - 动态javascript错误

Question

我正在尝试从后面的代码创建一个动态 javascript，它将被添加到页面中，从而使一个小的 jwplayer 能够打开，到目前为止我的代码:

void playAudioFile(string path)
    {
        string script =
        @"    var div = document.getElementById('playerDiv');
              var audio = document.createElement('audio');
              audio.setAttribute('id', 'audioPlayer');
              div.appendChild(audio);

              jwplayer(""audioPlayer"").setup({
              file: 'http://ps.staging.be/webservice/MP3DownloadHandler.ashx?id='" + path +
              @"'&date=' + '<%=Encrypt.EncryptString(String.Format(""{0:dd/MM/yyyy}"",
              DateTime.UtcNow))%>',
              width: ""100%"",
              height: ""30"",
              type: 'mp3',
              stretching: ""uniform"",
              controlbar: 'bottom'
          });
    ";

    //Add the script to it's tags
    HtmlGenericControl playScript = new HtmlGenericControl("script");
    playScript.InnerHtml = script;
    //Add it on his place
    playerDiv.Controls.Add(playScript);

但这结果是“无法与 localhost:55323 取得联系，有人知道我犯了什么错误吗？+ 有更好的方法吗？目的是在有人点击我的元素时显示播放器网站，播放器路径会根据所选项目而改变。如果你想比较一些东西，我有点像 youtube 这样的系统。

最终解决方案

string date = Encrypt.EncryptString(String.Format("{0:dd/MM/yyyy}", DateTime.UtcNow));
    string script =
    @"    var div = document.getElementById('ContentPlaceHolder1_playerDiv');
          var audio = document.createElement('audio');
          audio.setAttribute('id', 'audioPlayer');
          div.appendChild(audio);

          jwplayer(""audioPlayer"").setup({
              file: 'http://ps.staging.be/webservice/MP3DownloadHandler.ashx?id=" + path + @"&date=" + date + @"', 
              width: '100%',
              height: '30',
              type: 'mp3',
              stretching: 'uniform',
              controlbar: 'bottom'
          });
    ";

    //Add the script to it's tags
    HtmlGenericControl playScript = new HtmlGenericControl("script");
    playScript.InnerHtml = script;
    //Add it on his place
    playerDiv.Controls.Add(playScript);

你应该使用 ClientScript.RegisterStartupScript这样做:

Page.ClientScript.RegisterStartupScript(this.GetType(), "FooKey", script, true);

您在脚本中有一个代码块，不确定为什么不在代码中构建该字符串，然后将其附加到脚本中:

string date = Encrypt.EncryptString(String.Format("{0:dd/MM/yyyy}", DateTime.UtcNow));
string script =
    @"    var div = document.getElementById('playerDiv');
          var audio = document.createElement('audio');
          audio.setAttribute('id', 'audioPlayer');
          div.appendChild(audio);
          jwplayer(""audioPlayer"").setup({
          file: 'http://ps.staging.be/webservice/MP3DownloadHandler.ashx?id='" + path +  @"'&date=" + date + ", width: '100%', height: '30',type: 'mp3', stretching: 'uniform',controlbar: 'bottom'});";
