如何多个XMLHttpRequest

我想添加多个网站，我试图重写代码并更改链接“req.open”并注意完成。任何帮助？我对JavaScript很重要。感谢如何多个XMLHttpRequest

<html> 
<head> 
    <title>Testing Purposes</title> 
    <script lang="javascript"> 
     function ready() { 
      var hell = document.getElementById('hell'); 
      var req = new XMLHttpRequest(); 
      req.open('GET', 'load.php?http://www.140online.com/product/25965/%20%D8%AA%D9%82%D8%B7%D9%8A%D8%B9%20%D9%84%D9%8A%D8%B2%D8%B1', false); 


      req.send(null); 
      if(req.status == 200) { 
       var html_str = req.responseText; 
       var doc = document.createElement('html'); 
       doc.innerHTML = html_str; 
       var divs = doc.getElementsByClassName('row-fluid'); 
       for (i = 0; i < divs.length; i++) { 
        hell.innerHTML = hell.innerHTML + 
            "<h2>Found:</h2>" + 
            divs[i].innerText + 
            "<br />"; 
       } 
      } else { 
       alert("Failed to load the page!"); 
      } 
     } 
    </script> 
</head> 
<body onload="ready();"> 
    <div id='hell'> 
    </div> 
</body>

使用''XMLHttpRequest'处理来自服务器 – guest271314

我可以回应的load'事件在这行看到你错了：'req.open（'GET'，'load .PHP HTTP：//www.140online.com/product/25965/%20%D8%AA%D9%82%D8%B7%D9%8A%D8%B9%20%D9%84%D9%8A% D8％B2％D8％B1'，false）;'应该是'req.open（'GET'，'load.php？page = http：//www.140online.com/product/25965/%20%D8 ％AA％D9％82％D8％B7％D9％8A％D8％B9％20％D9％84％D9％8A％D8％B2％D8％B1'，false）;' –

使用此代码

<html> 
<head> 
    <title>Testing Purposes</title> 
    <script lang="javascript"> 
     function ready() { 
      var hell = document.getElementById('hell'); 
      var req = new XMLHttpRequest(); 
      req.open('GET', 'jsOnChange.php?page=http://www.140online.com/product/25965/%20%D8%AA%D9%82%D8%B7%D9%8A%D8%B9%20%D9%84%D9%8A%D8%B2%D8%B1', false); 


      req.send(null); 
      if(req.status == 200) { 
       var html_str = req.responseText; 
       document.innerHTML = html_str; 
       var divs = document.getElementsByClassName('row-fluid'); 
       alert(divs.length); 
       for (i = 0; i < divs.length; i++) { 
        alert('ok'); 
        hell.innerHTML += "<h2>Found:</h2>" + 
         divs[i].innerText + 
         "<br />"; 
       } 
      } else { 
       alert("Failed to load the page!"); 
      } 
     } 
    </script> 
</head> 
<body onload="ready();"> 
    <div id='hell'> 
    </div> 
    <hr> 
    <div class="row-fluid"> 
    Test 1 
    </div> 
    <div class="row-fluid"> 
    Test 2 
    </div> 
</body> 
</html>

我的结果
