Js和ajax进行交互

wisdom007

<script>
function apply(){
   var oForm = document.forms[0]; 
   var sBody = getRequestBody(oForm);
   var oXMLHttp = createXMLHttp(); // 取得 XMLHttp对象    
   oXMLHttp.open("post","/CSN/InterE2EServlet?type=2",true);    
   // 注意下面利用XMLHttp对象对请求头Content-Type的设置    
   oXMLHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
   oXMLHttp.onreadystatechange = function() {    
    if (oXMLHttp.readyState == 4) {    
     if (oXMLHttp.status == 200) {
     var orderNo = oXMLHttp.responseText;
     if(orderNo=="提交订单时出现错误!"){
      alert("提交订单时出现错误!");
     }else{
      if(confirm(orderNo+",是否要转到详细信息页面？")){
      window.location.href="/CSN/InterE2EServlet?type=4&ORDER_SERVICE_NO="+orderNo.substring(4);
      }
     }
    }    
   }    
  }
  oXMLHttp.send(sBody);
}
 
下面用到的是一个js导入到自己的文件中就可以了
