MVC + JQUERY + AJAX的几种方式
// 传过去一个简单值，获取一个简单值
$.ajax({
type: "GET",
url: '<%= Url.Action("xx", "Corp") %>',
data: "type=11",
success: function (msg) { alert(msg); }
});
public string xx()
{
string s = this.Request.QueryString["type"];
return s + ":ssssss";
}
// 获取一个复杂值
$.ajax({
url: '<%= Url.Action("xx", "Corp") %>',
type: "POST",
success: function(data) {
var obj = eval("(" + data + ")");
alert(obj.name);
}
});
// 这样更方便。
$.ajax({
url: '<%= Url.Action("xx", "Corp") %>',
type: "POST",
dataType:"json",
success: function(data) {
alert(data.name);
}
});
public ActionResult xx()
{
return this.Json( new
{
name = "Dr.Worm",
worm = "Programer"
} );
}
// 传过去一个复杂值，获取一个复杂值
$.ajax({
url: '<%= Url.Action("xx", "Corp") %>',
type: "POST",
dataType: "json",
data: "ID=1&FirstName=C&LastName=HY",
success: function(data) {
alert(data.ID + data.FirstName + data.LastName);
}
});
public JsonResult xx( FormCollection form )
{
return Json( new
{
ID = int.Parse(this.Request.Form[ "ID" ] ),
FirstName = "w:" + this.Request.Form[ "FirstName" ],
LastName = "s:" + this.Request.Form[ "LastName" ]
} );
}
客户端调用方式：

async: true, //异步

success: function(obj) {
alert(obj.ID + obj.FirstName + obj.LastName + obj.Man);
},

}
});
});

type: "POST", //默认是GET

success: function(obj) {

$("#ButAjax3").click(function() {
$.ajax({
