将webmethod参数传递给另一个Web方法 [英] passing webmethod parameter to another web method

问题描述

我们如何使用第一个Web方法中的Ajax在另一个Web方法中调用一个Web方法，我需要调用另一个Web方法并将参数从第一个方法传递给第二个方法

how can we call one web method in another web method using ajax from the first web method i need to call another web method and pass the parameters from the first to second method

<script type = "text/javascript">
    function GetCityNameArray() {
        var cities = ['Mumbai', 'Delhi', 'Chennai'];
        PageMethods.GetCityNameArray(cities, OnSuccessGetCityNameArray);
    }
    function OnSuccessGetCityNameArray(response) {
        for (var i in response) {
            alert(response[i]);
        }
    }
</script>

  <form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods = "true">
</asp:ScriptManager>

    <div>

<input type = "button" onclick = "GetCityNameArray()" value = "Get City Name Array" />

    </div>
    </form>

  protected void Page_Load(object sender, EventArgs e)
        {

        }

        [System.Web.Services.WebMethod]
        public static string[] GetCityNameArray(string[] cities)
        {
            return cities;
        }

推荐答案

首先创建控制器

     using System;
     using System.Collections.Generic;
     using System.Linq;
     using System.Web;
     using System.Web.Mvc;

    namespace DemoApp.Controllers
    {
        public class HomeController : Controller
        {
          public ActionResult Index()
           {
              return View();
            }

           public JsonResult Check(string name, string age)
           {
             string[] abc = { name, age };
             return Json(abc);
           }

         }
       }

然后创建您的视图

    @{
      ViewBag.Title = "Index";
     }
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/json2/20130526/json2.min.js">  </script>
    <script type="text/javascript">
       function GetData() {

         var name = txtName.value;
         var age = txtAge.value;
     jQuery.ajax({
        type: "Post",
        url: '@Url.Action("Check", "Home")',
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify({ name: name, age: age }),
        success: function (data) {
            alert("Name=" + data[0] + " And " + "Age=" + data[1]);
        }
    });
    return false;
   }



    </script>
   Name :<input id="txtName" type="text" />
   Age : <input id="txtAge" type="text" />
   <input id="btnSubmit" type="button" value="button" onclick="return GetData();" />
