五、js文件里调用后台代码


var basePath = "";
  if(typeof(glbRootPath) != "undefined"){ 
    basePath = glbRootPath;
    document.write("<script type='text/javascript' src='"+basePath+"\/dwr\/engine.js'><\/script><script type='text/javascript' src='"+basePath+"\/dwr\/interface\/CallTypeOpDwr.js'><\/script>");
  }
/*
中间省略若干代码
*/

.
if(typeof(glbRootPath) != "undefined"&&$(this).parent().children().eq(0).text()=="呼叫类型设置"){
        console.log("进来了");
        DWREngine.setAsync(false);
        CallTypeOpDwr.updateSp();
      }
