Layui表格多行删除与ID获取实现

<button class="layui-btn layui-btn-danger" data-type="getid" οnclick="delAll()">删除所有选中行</button>

table.on('checkbox(table)', function(obj){
 var data = obj.data;
});
layui.jquery, active = {
 getid: function () {
  var arr = [];
  var checkStatus = table.checkStatus('tableid')
   , data = checkStatus.data;
  for (var i = 0; i < data.length; i++) { //循环筛选出id
   arr.push(data[i].id);
  }
  $("#ids").val(arr);
 }
}
$('.layui-btn').on('click', function(){
 var type = $(this).data('type');
 active[type] ? active[type].call(this) : '';
});
function delAll(){
  layer.confirm('确定删除吗?', {btn: ['确定删除', '取消']}, function (index) {
   var a1 = $("#ids").val(); //取得已获取的ids
   $.ajax({ 
  .......  
   });
  });

}
