ajax获取后台数据,显示到input输入框里面

从后台获取数据放在输入框中

function readCard() {
$.ajax({
    url:\'/GetSlotCartServlet\',
    type:\'post\',
    data: {
        "serchCardId":$("#serchCardId").val(),
    },
    dataType:\'json\',
     success:function (result) {console.log(123)
         console.log(result.data);
         console.log(result)
                 var res = result.data;
                 // console.log(data.userId)
                 $("#userId").val(res.userId);
                 $(\'#userName\').val(res.userName),
                 $("#cardId").val(res.cardId),
                 $("#amout").val(res.amout),
                 $("#cardLevel").val(res.cardLevel),
                 $("#credit").val(res.credit)
         }
     });

使用了上面那个输入框获取不到,折腾半天,在13行加个下标就好了

解决

function readCard() {
$.ajax({
    url:\'/GetSlotCartServlet\',
    type:\'post\',
    data: {
        "serchCardId":$("#serchCardId").val(),
    },
    dataType:\'json\',
     success:function (result) {console.log(123)
         console.log(result.data[0]);
         console.log(result)
                 var res = result.data[0];获取结果下标第一个
                 // console.log(data.userId)
                 $("#userId").val(res.userId);
                 $(\'#userName\').val(res.userName),
                 $("#cardId").val(res.cardId),
                 $("#amout").val(res.amout),
                 $("#cardLevel").val(res.cardLevel),
                 $("#credit").val(res.credit)
     }
 });

}
