【问题描述】：
我想显示从 db 循环的复选框，如果我尝试在字段中选择数据 id_kendaraan 然后显示来自该 id 的数据。
这是我的视图代码：
<div class="modal fade" id="tambah" tabindex="-1" role="dialog" aria-labelledby="largeModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
<h3 class="modal-title" id="myModalLabel">Tambah Pemeliharaan</h3>
</div>
<form class="form-horizontal" method="post" action="<?php echo base_url()?>Data/Pemeliharaan/Tambah">
<div class="modal-body">
<div class="form-group">
<label class="control-label col-xs-3">Nama Kendaraan</label>
<div class="col-xs-8">
<select class="form-control" name="id_kendaraan" id="id_kendaraan" required>
<option>Pilih Kendaraan</option>
<?php
if(!empty($kendaraan_)) {
foreach ($kendaraan_ as $isi) {
?>
<option value="<?php echo $isi['id_kendaraan']?>"><?php echo $isi['nama']?> - <?php echo $isi['platno']?></option>
<?php }} ?>
</select>
</div>
</div>
<?php
$index =0;
foreach ($subkriteria_ as $kr_key => $kriteria) {
?>
<div class="form-group">
<label class="control-label col-xs-3"><?php echo $kriteria['nama_kriteria'] ?></label>
<div class="col-xs-8">
<input type="hidden" name="status_pemeliharaan" value="1" class="form-control">
<input type="hidden" name="id_kriteria[]" value="<?php echo $kriteria['id_kriteria'] ?>" class="form-control">
<?php if(!empty($kriteria['sub'])) { ?>
<select class="form-control" name="isi_kriteria[]" required>
<option>Pilih Sub Kriteria</option>
<?php $no = 1; foreach ($kriteria['sub'] as $data) { ?>
<option value="<?php echo $data['value'] ?>"><?php echo $data['namasubkriteria'] ?> - <?php echo $data['value'] ?></option>
<?php $no++; } ?>
</select>
<?php } else if($kriteria['link']=='tahun_beli') { ?>
<input name="isi_kriteria[]" value="" class="form-control" type="text" placeholder="Isi Kriteria..." readonly required>
<?php } else { ?>
<input name="isi_kriteria[]" value="" class="form-control" type="number" placeholder="Isi Kriteria..." required>
<?php } ?>
</div>
</div>
<?php } ?>
<div class="form-group">
<label class="control-label col-xs-3"></label>
<div class="col-xs-8">
<ul id="sparepartList" style="list-style-type: none; padding: 0;"></ul>
</div>
</div>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Tutup</button>
<button class="btn btn-info">Submit</button>
</div>
</form>
</div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function(){
$('#id_kendaraan').on('input',function(){
var id_kendaraan=$(this).val();
$.ajax({
type : "POST",
url : "<?php echo base_url('Data/Pemeliharaan/GetKendaraanById')?>",
dataType : "JSON",
data : {id_kendaraan: id_kendaraan},
cache:false,
success: function(data){
$('#sparepartList').empty(); // clear all sparepart checkboxes
$.each(data, function(id_kendaraan, tahun_beli, id_jenis){
$('[name="isi_kriteria[]"]').val(data.tahun_beli);
$('[name="id_jenis"]').val(data.id_jenis);
$.each(data.spareparts, function (key, value) {
let li = $('<li><input type="checkbox" name="id_sparepart[]" value="' + value.id_sparepart + '" />' +
'<input type="text" name="sparepart" value="' + value.sparepart + '" /></li>');
$('#sparepartList').append(li);
});
});
}
});
return false;
});
});
</script>
我的控制器：
function GetKendaraanById(){
$id_kendaraan=$this->input->post('id_kendaraan');
$data=$this->PemeliharaanModel->GetById($id_kendaraan);
echo json_encode($data);
}
我从视图 $id_kendaraan 获取数据作为我的参数。
这是我的模特：
function GetById($id_kendaraan){
$this->db->select('*');
$this->db->from('tb_kendaraan');
$this->db->where('tb_kendaraan.id_kendaraan',$id_kendaraan);
$query_kendaraan = $this->db->get();
$hasil = false;
if($query_kendaraan->num_rows() > 0)
{
$data_kendaraan = $query_kendaraan->row();
$hasil = [
'tahun_beli' => $data_kendaraan->tahun_beli,
'id_jenis' => $data_kendaraan->id_jenis,
'spareparts' => [] // empty array, to be filled with spareparts data
];
$this->db->select('*');
$this->db->from('tb_sparepart');
$this->db->where('tb_sparepart.id_jenis', $data_kendaraan->id_jenis);
$query_sparepart = $this->db->get();
foreach ($query_sparepart->result() as $data_sparepart) {
$spareparts = [
'id_sparepart' => $data_sparepart->id_sparepart,
'sparepart' => $data_sparepart->sparepart,
];
array_push($hasil['spareparts'], $spareparts);
}
}
return $hasil;
}
但如果我尝试此代码，字段 tahun_beli，id jenis 将成功显示在视图中。但备件中的复选框被夸大了。
我试试json，数据是正确的，显示tahun_beli，id_jenis，是显示和sparepart是id_jenis显示
但鉴于我尝试此代码...tahun_beli 和id_jenis 是正确的显示一个数据，但sparepart 正在循环 3 次.. 备件应该显示数据 1 次...
