大家帮忙看看，这个AJAX的SUCCESS方法怎么没收到JS文件呢？
$.ajax({
url:"/ware_subject/GetPs",
data:"",
type:"post",
datatype:"text",
success:function(data){
alert("success");
},
error:function()
{
alert("error");
}
});
controller:
public void GetPs()
{
response.wirtefile("/Scripts/aa.js");
}aa.js:
alert("nihao");结果是。aa.js 直接在页面执行了，AJAX。的SUCCESS没有收到数据呢？
如何让aa.js不直接执行，而是传到AJAX的SUCCESS的方法里面。应该怎么写呢？

我在网上找了很久都没找到相关的知识！
网上操作XML的就比较多，我就想把JS放到XML文件中操作应该比较方便吧?
File.ReadAllText("")字符串
Controller里面，转到一个View
