php - 如何从jquery访问json编码的php数组

Question

我有一个这样的脚本:

$(document).on("click", ".passingID", function () {
         var ids = $(this).attr('data-id');
         $("#idkl").val( ids );
         $.ajax({
              method: "POST",
              url: "getidforeditkaryawan.php",
              data: { idkl: ids}
        }).done(function(data) {
            console.log(data);
            $("#nik").val(data['nik']);
            $("#ktp").val(data['ktp']);
            $("#status").val(data['status']);
            $("#nama").val(data['nama']);
            $("#bank").val(data['bank']);
            $("#norek").val(data['norek']);
            $("#tglmsk").val(data['tgl_msk']);
            $("#tglkl").val(data['tgl_keluar']);
            $("#idp").val(data['id_perusahaan']);
            $("#tlk").val(data['tlk_individu']);
          }).fail(function( jqXHR, textStatus ) {
              console.log(jqXHR, textStatus);
        });
    });

这是 getidforeditkaryawan.php 文件:

<?php
   $con = mysqli_connect("127.0.0.1","root","","penggajian"); 
   $sql = "SELECT * FROM karyawan_lapangan WHERE id_kl = '".$_POST['idkl']."'";
   $getdatakaryawan = mysqli_query($con,$sql);
   $data = mysqli_fetch_assoc($getdatakaryawan);
   print_r(json_encode($data));
?>

但每次我尝试像这样打印“data”变量内的值

console.log(data['nik']);

该值不会出现

print_r(json_encode($data)); 的结果是这样的:

{"id_kl":"4","nik":"13","ktp":"1231231","status":"aktif","nama":"ardia","bank":"asdasd","norek":"21313","tgl_masuk":"2019-02-14","tgl_keluar":"0000-00-00","id_perusahaan":"3123121","tlk_individu":"4124124"}

Answer 1

由于您返回一个 json 对象，您可以像这样访问它:

$("#nik").val(data.nik);

根据04FS评论进行编辑:

 $.ajax({
              method: "POST",
              dataType: "json",
              url: "getidforeditkaryawan.php",
              data: { idkl: ids}
        }).

错过了那个地方，他是对的。
