对于此方法调用之后会一直返回undefined，原因是Jquery的ajax是异步的，所以大多时候没执行完AJAX就return htmlcontent了，所以会一直返回undefined,
解决方法：添加async: false,即修改此方法为同步
- function GetUserInfo(tp) {
- var username;
- $.ajax({
- type: "POST",
- cache: false,
- data: "type=exlogin&tp=" + tp,
- async: false,
- url: "Handle/OpeartionHandler.ashx",
- success: function(userinfo) {
- username = userinfo;
- }, error: function(data) {
- username = "";
- }
- });
- return username;
- }
