使用Ajax获取数据未定义

我一直坚持通过Ajax从数据库获取结果。 id =“ view_errorcode”正在工作,但id =“ view_vlokasi”不起作用,只是显示UNDEFINED。有人可以告诉我我在代码中做错了什么吗?

$('#showdata').on('click', '.item-info', function(){
  var tid = $(this).attr('data');
  $.ajax({
    type: 'ajax',
    method: 'get',
    url: '<?php echo base_url() ?>RepeatProblem/infoReprob',
    data: {tid:tid},
    async: false,
    dataType: 'json',
    success: function(data){
      var vlokasi = '<span style="font-size:22px;color:green">'+data.lokasi+'</span>';
      var html = '';
      var i;
      for(i=0; i<data.length; i++){
        html +='<p style="font-size:18px;color:black"><i class="fa fa-check"></i> '+data[i].lokasi+' '+data[i].updated_at+'<br>'+data[i].ketprob+'</p>';
      }

      $('#infoModal').modal('show');
      $('#view_lokasi').html(vlokasi); // showing UNDEFINED
      $('#view_errorcode').html(html); // Working
    },
    error: function(){
      alert('Gagal Info Kode Error!');
    }
  });
});

ajax调用返回以下json

[{"tid":"550250","ketprob":"1","updated_at":"15-09-2018 19:39","lokasi":"ERA MART TENGKAWANG"},{"tid":"550250","ketprob":"2","updated_at":"15-09-2018 19:39","lokasi":"ERA MART TENGKAWANG"},{"tid":"550250","ketprob":"3","updated_at":"15-09-2018 19:39","lokasi":"ERA MART TENGKAWANG"},{"tid":"550250","ketprob":"4","updated_at":"15-09-2018 19:37","lokasi":"ERA MART TENGKAWANG"}]

看起来像是对象数组,因此您无法访问lokasi属性,而不会循环数组。试试这个:

var lokasi;
for(var i = 0; i < data.length; i++) {
lokasi = data[i].lokasi;
...

或者您可以从类似项中获得特定元素

data[0].lokasi 

data[n].lokasi
