科尔多瓦inappbrowser getElementsByClassName

Question

我正在尝试抓取网站内容。

为了进行测试，我尝试将Stackoverflow加载到inAppBrowser中并获取其内容。这就是我尝试过的

 var code = "alert(document.getElementsByClassName('question-hyperlink').length)";
 var win = window.open('https://stackoverflow.com/questions/20937196/retrieving-source-code-of-site-in-inappbrowser/', '_blank', 'location=yes');

 win.addEventListener('loadstop', function(event) { 
          //wait 1 second till page load
          setTimeout(function(){
                  win.executeScript({
                          code: code,
                  }, function() {
                          console.log('script was injected successfully');
                  });
          }, 1000);

 });

它仅返回值1

但是该页面有超过35个元素，类为question-hyperlink。如何从inApp正确访问内容
