Laravel实现异步修改分类排序

后台Model方法：

public function getCategories(){
    $categories = $this->orderBy('cate_order','asc')->get();
    return $this->getTree($categories,'cate_name','cate_id','cate_pid',0);
  }

Controller方法：

  // change order
    public function changeOrder(){
      $input = Input::all();
      $cate = Category::find($input['cate_id']);
      $cate->cate_order = $input['cate_order'];
      $res = $cate->update();
      if ($res) {
        $data=[
          'status'=>0,
          'msg'=>'分类排序更新成功!',
        ];
      } else {
        $data=[
          'status'=>1,
          'msg'=>'分类排序更新失败，请稍后重试!',
        ];
      }
      return $data;
    }

前端使用了layerUI框架

<input type="text" onchange="changeOrder(this,{{ $category->cate_id }})" class="order" value="{{ $category->cate_order }}">

<script type="text/javascript">
  function changeOrder(obj,cate_id){
    var cate_order=$(obj).val();
    $.post("{{ url('admin/category/changeorder') }}",{'_token':"{{ csrf_token() }}",'cate_id':cate_id,'cate_order':cate_order},function(data){
      if (data.status==0) {
        layer.msg(data.msg, {icon: 6});
      } else {
        layer.msg(data.msg, {icon: 5});
      }
    });
  }
</script>
<script async defer src="{{ asset('admin/assets/layer/layer.js') }}"></script>
