All that’s needed now is some Javascript for the getEmployees() method that has been assigned to the onclick event of the html button. This will go into the section of the page:

$(function() {

$(‘#Button1’).click(getEmployees);

});

function getEmployees() {

$.ajax({

type: “POST”,

url: “Employeeservice.asmx/GetAllEmployees”,

data: “{}”,

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

dataType: “json”,

success: function(response) {

var Employees = (typeof response.d) == ‘string’ ? eval(‘(‘ + response.d + ‘)’) : response.d;

$(‘#output’).empty();

for (var i = 0; i < Employees.length; i++) {

$('#output').append('

‘ + Employees[i].lastname + ‘ ‘ +

Employees[i].firstname + ‘
Age: ‘ +

Employees[i].age + ‘
Doors: ‘ +

‘);

}

},

failure: function(msg) {

$(‘#output’).text(msg);

}

});

}
