利用JQuery的$.ajax()调用.Net后台方法有多种方式，
不多说了 直接上代码
前台代码
<script type="text/javascript">
$(document).ready(function () {
getTreeData(getData());
});
//获取ajax调用传参方法
function getData() {
var data = {};
data.username = "an";
data.id = "2";
return data;
}
var getTreeData = function (data) {
$.ajax({
//界面URL传参数调用
url: "Edit_super.aspx?method=GetNodeData&dataId=1",
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
//Response.Write 方式返回数据
success: function (dataReturn) {
$.fn.zTree.init($("#treeDemo"), setting, dataReturn);
$("#selectAll").bind("click", selectAll);
},
error: function () {
}
});
};
var getTreeData = function (data) {
$.ajax({
// 调用后台方法方式
url: "Edit_super.aspx/GetValueAjax",
//传入参数
data: "{id:'" + data.id + "'}",
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
//解析返回的json数据
success: function (dataReturn) {
var datar=$.parseJSON(dataReturn.d);
$.fn.zTree.init($("#treeDemo"), setting, datar);
$("#selectAll").bind("click", selectAll);
},
error: function () {
}
});
};
var getTreeData = function (data) {
//MVC 调用方式
$.ajax({
url: '../GetValue/GetValueAjax',
type: "POST",
data: data,
success: function (dataReturn) {
//解析返回数据
var ss = $.parseJSON(dataReturn);
},
error: function () {
}
});
};
</script>
后台代码

{

{
