Passing Webmethod Parameter To Another Web Method

November 30, 2022 Post a Comment

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

Solution 1:

first Create Controller

     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);
           }

         }
       }

then create Your view

    @{
      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();" />

Solution 2:

When you click, does it actually fires the click function? Did you debug it? If not, first try to put a breakpoint in the first line inside the click function or add a simple alert("click works"), maybe your selector is wrong.

Solution 3:

Also we can write the following solution in controller and fill the EmployeeDto in view side pass to controller.

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(EmployeeDto EmployeeDto)
           {
             string[] abc = { EmployeeDto.name, EmployeeDto.age };
             return Json(abc);
           }

         }
       }

Solution 4:

There can be a few corrections first of all you need document.ready event or another helper function (i changed to a helper function due to asp.net's clientid thing) and then you have to stop button posting back your page.

script type="text/javascript">
    var onSubmitClick = function() {
            var button = this;
            var obj = {};
            obj.name = $.trim($("[id*=txtName]").val());
            obj.age = $.trim($("[id*=txtAge]").val());
            $.ajax({
                type: "POST",
                url: "CS.aspx/SendParameters",
                data: JSON.stringify(obj),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (r) {
                    alert(r.d);
                }
            });
            return false;
    };
</script>

</head>
<body>
    <form id="form1" runat="server">
    <div>

<table border="0" cellpadding="0" cellspacing="0">
<tr>
    <td>
        Name:
    </td>
    <td>
        <asp:TextBox ID="txtName" runat="server" Text = "" />
    </td>
</tr>
<tr>
    <td>
        Age:
    </td>
    <td>
        <asp:TextBox ID="txtAge" runat="server" Text = ""/>
    </td>
</tr>
<tr>
    <td>
        <asp:Button ID="btnSubmit" Text="Submit" runat="server" OnClientClick="return onSubmitClick();" UseSubmitBehaviour="false" />
    </td>
</tr>
</table>

protected void Page_Load(object sender, EventArgs e)
        {

        }

        [System.Web.Services.WebMethod]
        public static string SendParameters(string name, int age)
        {
            return string.Format("Name: {0}{2}Age: {1}", name, age, Environment.NewLine);
        }
