Question

我的代码html如：

$.ajax({
  type: "POST",
  url: "hanca/hanca_crud.php",
  dataType: 'json',
  data: {
    id_hanca: id_hanca,
    type: "detail_hanca"
  }, //detail_hanca
  success: function(data) {

    var teks = "";
    $.each(data.detail, function(indeks, nilai) {
      //status hanca
      var tmp1 = nilai.status_detail_hanca;
      $("select.status_detail_hanca").val(tmp1);

      var no = nilai.no;
      var status_detail_hanca = "<select class='status_detail_hanca' name='status_detail_hanca[]' ><option value='0'>Proses</option><option value='1'>Return</option><option value='2'>Selesai</option></select>";
      teks += "<tr>" + no +
        "</td><td>" + status_detail_hanca +
        "</td></tr>";
    });
    $(".tbody_detail_hanca_checking").append(teks);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<table>
  <thead>
    <tr>
      <th>No.</th>
      <th>Status Proses</th>
    </tr>
  </thead>
  <tbody class="tbody_detail_hanca_checking">
  </tbody>
</table>

并输出json：

{
	"detail": [{
		"status_detail_hanca": "2",
		"no": 1
	}, {
		"status_detail_hanca": "0",
		"no": 2
	}]
}

我使用ajax通过json获取数据，我想创建一个select option并从json设置value数据。但是，它不起作用。如何解决？

允许代码的文本虚拟 Lorem ipsum dolor坐下来，精神上的adipiscing elit。 Morbi vel fermentum massa，quis viverra lectus。 Aliquam tristique feugiat volutpat。 Donec elementum sapien vel enim facilisis sollicitudin。 Integer pellentesque volutpat enim

Answer 1

$("select.status_detail_hanca").val(tmp1);

这不起作用，因为您在编写选择选项之前设置了选项 - $(".tbody_detail_hanca_checking").append(teks);

所以试试这个。

    $.ajax({
  type: "POST",
  url: "hanca/hanca_crud.php",
  dataType: 'json',
  data: {
   id_hanca: id_hanca,
   type: "detail_hanca"
  }, //detail_hanca
  success: function(data) {

    var teks = "";
    $.each(data.detail, function(indeks, nilai) {
      //status hanca
      var tmp1 = nilai.status_detail_hanca;
      $("select.status_detail_hanca").val(tmp1);

      var no = nilai.no;
      var status_detail_hanca = "<select class='status_detail_hanca' name='status_detail_hanca[]' >\n\
        <option value='0'";
        if(tmp1 === '0') {
            status_detail_hanca += " selected ";
        }
      status_detail_hanca += ">Proses</option>\n\
        <option value='1'";
        if(tmp1 === '1') {
            status_detail_hanca += " selected ";
        }
      status_detail_hanca += ">Return</option>\n\
        <option value='2'";
        if(tmp1 === '2') {
            status_detail_hanca += " selected ";
        }                
      status_detail_hanca += ">Selesai</option>\n\
        </select>";
      teks += "<tr>" + no +
        "</td><td>" + status_detail_hanca +
        "</td></tr>";
    });
    $(".tbody_detail_hanca_checking").append(teks);
  }
});

jquery从json中选择选项设置值
