server side c# method is not calling from ajax - asp.net

Question

I am trying to call a c# method using ajax as below.

<a href="#divrecentQ" id="linkdivrecentQ" onclick="lnkClick();" aria-controls="divrecentQ" role="tab" data-toggle="tab">Click here</a>

Here is the method in JS

    function lnkClick() {
        alert("called");
        $.ajax({
            type: "POST",
            url: '/amain.aspx/LoadImages',
            data: {},
            success: function () {
                alert(1);
            },
            dataType: 'html'
        });
        alert("cal");
    }

Server side:

    public static void LoadImages()
    {
       
        log.Debug("LoadImages is called");
       
    }

Server side method is not getting called.

Can someone please help?

Thanks

Have look my answer of previous question [Stackoverflow link](http://stackoverflow.com/a/36589613/4611027) make sure function is call after initialize of jQuery — Syed Mhamudul Hasan, Nov 07 '16 at 14:33
Please refer this : http://stackoverflow.com/questions/23033614/asp-net-calling-webmethod-with-jquery-ajax-401-unauthorized. If you have routeConfig file under App_Start, you need to change the AutoRedirectMode — rach, Nov 07 '16 at 14:37
Add error function for ajax so you will see the error message in your console. — rach, Nov 07 '16 at 14:43
@rach. yes it worked. but now it is executing everytime page loads.. I want it to be called only on link click. any suggestion? — Dheeraj Kumar, Nov 07 '16 at 14:47

You should define the method static and wrap it with [WebMethod] attribute.

[WebMethod]
public static void LoadImages()
{

    Label1.Text = "hi therre";
    Response.Redirect("www.google.com");
    log.Debug("LoadImages is called");

}

@DKR put breaking point in load images check if it is going in the method. IF it is not check your console for errors from javascript side – mybirthname Nov 07 '16 at 14:17
it is not going in method. How do I start console to chek js errors? – Dheeraj Kumar Nov 07 '16 at 14:17
@DKR in chrome right mouse click-> Inspect-> Second tab -> Console. Clear the console try to execute your ajax check for errors. – mybirthname Nov 07 '16 at 14:18
It gives error as "undefined". but not about which symbol – Dheeraj Kumar Nov 07 '16 at 14:23
There is no error for js, undefined is something else... dunno whats causing this. anyway thanks for your time. appreciate it – Dheeraj Kumar Nov 07 '16 at 14:29

Adding "contentType: "application/json; charset=utf-8"," in jquery called the server side method.
