在数据表的新行中添加按钮,获取未定义的

我有一个javascript对象,我试图在数据表中添加一个新行。一列是字段,另一列应包含按钮。

var appendLastCategory = function() {
    var obj = {
        id: 'jh2i4h34ubi43',
        name: 'Lolo',
    };
    $('#categoriesList').DataTable().row.add({
        name: obj.name, //First column
        mRender: function() { //Second column
            return "<a class='md-btn' onClick='deleteCategory(this, &quot;" + obj.id + "&quot;)'>Delete</a>";
        }
    }).draw();
};

然后当我点击&#34;删除&#34;按钮,我得到&#39; undefined&#39;在&#39; id&#39;值。而且我不知道为什么,因为当我初始化表格时,用初始数据填充它并使用&#39; mRender&#39;它的工作方式大致相同。

var deleteCategory = function(element, id) {
    console.log(id);
    //Blah blah, all the code to delete on backend and remove the row
};

我希望这可以提供帮助:

&#13;
var deleteCategory = function(element, id) {
  alert(id);
  //Blah blah, all the code to delete on backend and remove the row
};
var appendLastCategory = function () {
  var obj = {
    id: 'jh2i4h34ubi43',
    name: 'Lolo',
  };
  $('#categoriesList').DataTable().row.add({
    '0': obj.name, //First column
    '1': "<a href='#' class='btn btn-info' role='button' onClick='deleteCategory(this, &quot;" + obj.id + "&quot;)'>Delete</a>",
  }).draw();
};

$(function () {
  appendLastCategory();
});

感谢您的回复!我已经解决了。

要初始化DataTable,请使用以下代码:

var datax = [{
      id: '67i67i634r2r',
      name: 'Lala',
   },{
      id: 'g45y45y657t3',
      name: 'Lele',
   }];
$('#categoriesList').DataTable({
    "data": datax,
    "columns": [
        { data: "name" }, {
            render: function(o, type, data) {
                return "<a class='md-btn' onClick='deleteCategory(this, &quot;" + data.id + "&quot;)'>Delete</a>";
            }
        }
    ]
});

在最后,只需以这种方式添加javascript对象,所有内容都得到了解决。希望这会帮助更多人。

var appendLastCategory = function () {
   var obj = {
      id: 'jh2i4h34ubi43',
      name: 'Lolo',
   };
   $('#categoriesList').DataTable().row.add(obj).draw();
};
