jquery ajax为什么获取的data.d是object httprequest?
$.ajax({
type: "Post",
url: "demo.aspx/GetStr",
//方法传参的写法一定要对，str为形参的名字,str2为第二个形参的名字
data: "nickname=" + $("#<%=nickname.ClientID %>").val(),
// beforeSend: function (XMLHttpRequest) {
// $("#nickinfo").text("正在查询");
// //Pause(this,100000);
// },
async: false,
contentType: "application/json; charset=utf-8",
dataType: "html",
success: function (data) {
//返回的数据用data.d获取内容
$("#nickinfo").text(data.d);
alert(data.d);
},
error: function (err) {
alert(err);
}
});
