最近遇到一个问题纠结了我一个多月:
由于代码是比较老的版本，所以ajax是调用 的webservice 而不是批处理文件.ashx文件
代码：
js:
$.ajax({
type: "POST",
contentType: "application/json",
url: "WebService.asmx/GetIndexFocusPics",
data: "{}",
dataType: 'json',
success: function(result) {
alert(result);
}
});
webservice.cs:
/// <summary>
/// 获取首页焦点图广告
/// </summary>
/// <param name="typeID"></param>
/// <returns></returns>
[WebMethod]
public string GetIndexFocusPics()
{
return BindFocusHtml("UP_GET_Index_FocusPicList", 600, 165);
}
别人交手给时，在别人电脑上 :&.ajax返回的result 是object var test=result
而我电脑上result 是object object 而我要用result.d 才能获取的值
var test=result.d;
折磨了我一个月后才发现 是.net 版本问题，当时什么都改了，就是没想起web.config不一样。
项目中：

就这个问题。。好像改变.net 由2.0转到3.5时，ajax中的版本有变动，，结果返回值就不一样了。。
具体中间细节请高手指教。。。。？？？？？？
