1、控制器

package controllers

import (
    "fmt"
    "github.com/astaxie/beego"
    "yunlaba/crm-web/models"
)

type MapController struct {
    beego.Controller
}



func (c *MapController) Get() {
    c.TplName = "map.html"
}

func (c *MapController) Update()  {
    fmt.Println("是否为ajax请求",c.IsAjax())
    //c.Data["json"]= `[{"name":"cxh","sex":"man"},{"name":"cxh1","sex":"man1"}]`

    c.Data["json"] = models.GetData()
    c.ServeJSON()

}

2、路由设置

package routers

import (
    "yunlaba/crm-web/controllers"
    "github.com/astaxie/beego"
)

func init() {
    beego.Router("/", &controllers.MainController{})
    beego.Router("/map", &controllers.MapController{})
    beego.Router("/map/Update",&controllers.MapController{},"*:Update")
}

3、前端页面调用

function ajaxRequest() {
        $.ajax({
            url: "{{urlfor "MapController.Update"}}",
            async: false,
            type: "GET",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            error: function (xhr) {
                alert("错误提示： " + xhr.status + " " + xhr.statusText);
            },
            success: function (data) {
                lations=data;
            }
        });

        // alert(t)
    }
