javascript中的javascript bug json数据

Question

我试图在HTML页面中以表格格式从JSON文件获取数据，但是我收到错误。

  

未捕获的TypeError：$ .getJSON不是函数

我该如何解决这个问题？

$(document).ready(function()
  $.getJSON("Info.json", function(data) {
    var Employee_info = '';
    $.each(data, function(key, value) {
      Employee_info += '<tr>';
      Employee_info += '<td>' + value.Name + '</td>';
      Employee_info += '<td>' + value.Address + '</td>';
      Employee_info += '<td>' + value.Gender + '</td>';
      Employee_info += '<td>' + value.Designation + '</td>';
      Employee_info += '<td>' + value.Age + '</td>'
      Employee_info += '</tr>'
    });
    $('#Employee_table').append(Employee_info);
  });
});
