Question

我想从nodejs获取数组数据。特别是我很期待获得使用Jquery检索数据但无法的每个结果的文件名。我不知道该怎么做。

router.post('/womensearch',(req,res)=>{
const searchItem = req.body.womenitem;
// If it is Catagory
gfs.collection('wdress').find({
    $and:[{ $or : [{'metadata.cat': searchItem},{'metadata.brand': 
searchItem}]}]
   }).toArray((err,files)=>{

    res.end(JSON.stringify(files)); <- Here is my problem

  });
});

这是Jquery代码

      function womenSearch(){
          $(document).ready(function(){
            const search_item = $('#womenItem').val();
            $.ajax({
              method:'POST',
              url:'/womensearch',
              cache:false,
              data:{
                womenitem:search_item
              },
              success:function(data){


              },
              error:function(){

              }
            });

          });
        }


        </script>

这是我从数据库中获得的结果。

通过Jquery回调函数发送数据的任何提示。

Answer 1

您需要先将结果解析为json，然后才能访问它。

resultJSON = JSON.parse(data);
