ajax向php服务端请求数据用datables显示400 请求报错

在 AJAX 获取数据，再将 dom 节点更新、或者添加，最后在初始化 dataTable

$ ( document ).ready(function() { $.ajax({ type: 'GET', url: 'models/summary.php', mimeType: 'json', success: function(data) { $.each(data, function(i, data) { var body = "<tr>"; body    += "<td>" + data.name + "</td>"; body    += "<td>" + data.address + "</td>"; body    += "<td>" + data.phone_no + "</td>"; body    += "<td>" + data.birthday + "</td>"; body    += "<td>" + data.color + "</td>"; body    += "<td>" + data.car + "</td>"; body    += "<td>" + data.hobbies + "</td>"; body    += "<td>" + data.relatives + "</td>"; body    += "</tr>"; $( "#summary-table tbody" ).append(body); }); /DataTables instantiation./ $( "#summary-table" ).DataTable(); }, error: function() { alert('Fail!'); } }); });
