Calling a function in javascript anchor tag

 <a class="link-offset-2 link-offset-3-hover link-underline link-underline-opacity-0 link-underline-opacity-75-hover" style="cursor: pointer" onclick="showCaseProfile(\'' + value.FileNumber + '\');">' + value.FileNumber + '</a>

function showCaseProfile(CaseNo) {

    var params = { strCNR_No: CaseNo };

    $.ajax({

        type: "POST",

        contentType: "application/json; charset=utf-8",

        url: '../DashboardReports/DashboardReports.aspx/CNREncryption',

        data: JSON.stringify(params),

        dataType: "json",

        success: function (data) {

            window.open('../DashboardReports/CaseProfile.aspx?CaseNo=' + data.d, '_blank');

        },

        error: function (result) {

            alert("Server Connection Error");

        }

    });

}

Jquery ajax - ASP.NET when exception occur in asp.net

 success: function(data) {

  if (typeof data == "string")

    data = JSON.parse(data);

  if (data.success) {

    // Code if success.

  } else {

    // Code if error.

  }

},

and when method not found, than it will gone to error or any function not called by ajax call.

 $.ajax({
    type: "POST",
    data: formData,
    url: "/Forms/GetJobData",
    dataType: 'json',
    contentType: false,
    processData: false,               
    success: function (response) {
        if (response.success) {
            alert(response.responseText);
        } else {
            // DoSomethingElse()
            alert(response.responseText);
        }                          
    },
    error: function (response) { // // Added this event to capture the failed requests.

        alert("error!");  // 
    }

});
