Ajax通用模板实现代码

复制代码 代码如下:

  <script type="text/javascript">

  var xmlHttp;

  function creatXMLHttpRequest() {

  if (window.ActiveXObject) {

  xmlHttp = new ActiveXObject("Microsoft.XMLHttp");

  }

  else if (window.XMLHttpRequest) {

  xmlHttp = new XMLHttpRequest();

  }

  }

  function startRequest() {

  creatXMLHttpRequest();

  xmlHttp.onreadystatechange = handleStateChange;

  xmlHttp.open("GET", "simpleResponse.xml", true);

  xmlHttp.send(null);

  }

  function handleStateChange() {

  if (xmlHttp.readyState == 4) {

  if (xmlHttp.status == 200) {

  // document.getElementById("results").innerHTML = xmlHttp.responseText;

  // alert("The server replied with:" + xmlHttp.responseText);

  }

  }

  }

  </script>
