【问题描述】：
我正在尝试使用相关的下拉列表框将过滤器应用于我的数据表。但是当我尝试从下拉列表中选择一个值时，数据表只从一个下拉列表中获取值。
这是我的代码：
脚本：
<script type="text/javascript">
$(document).ready(function(){
var dataTable = $('#exampleProp').DataTable({
"processing": true,
"serverSide": true,
"dom": 'lfrtip',
"ajax": {
"url": "<?= base_url('Property/fetchProp'); ?>",
"dataType": "json",
"type": "POST"
},
"lengthMenu": [[50, 100, 200, -1], [50, 100, 200, "All"]],
// "ordering": false,
});
$('#areaId').on('change', function(){
if (this.value == 1) {
dataTable.search("Midlands & East of England").draw();
} else {
dataTable.search("North East, Yorkshire & Humberside").draw();
}
});
$('#cluster_id').on('change', function(){
dataTable.search(this.value).draw();
});
$('#prop_type').on('change', function(){
dataTable.search(this.value).draw();
});
$('#prop_status').on('change', function(){
dataTable.search(this.value).draw();
});
});
</script>
在此，Cluster 依赖于 Area，但如果我选择 Area，它将仅使用区域进行过滤，而不是按集群。
这是从数据库中选择集群列表的代码：
$('#areaId').change(function(){
var form_date =
$.ajax({
url: "<?= base_url('Property/clusterlistAddPropertyUse'); ?>",
data: {areaId:$(this).val()},
method:'POST',
dataType: 'html',
success:function(data){
// $('#cluster_id option:selected').each(function(){
// $(this).prop('selected', false);
// });
$('#cluster_id').html(data);
$('.propcluster').multiselect('rebuild');
}
});
});
这是我的视图代码：
<?php if($this->session->flashdata('success_msg')){ ?>
<div class="alert alert-success">
<?php echo $this->session->flashdata('success_msg'); ?>
</div>
<?php } ?>
<?php if($this->session->flashdata('error_msg')){ ?>
<div class="alert alert-danger">
<?php echo $this->session->flashdata('error_msg'); ?>
</div>
<?php } ?>
<div class="panel panel-default" id="refresh">
<div class="panel-heading">
<b>Property List</b>
</div>
<div class="panel-body">
<div class="col-md-3">
<label>Area:</label>
<select class="form-control select2" name="area_id" id="areaId">
<option>All</option>
<?php foreach ($areas as $area) { ?>
<option value="<?= $area->area_id; ?>"><?php echo $area->area_name; ?></option>
<?php } ?>
</select>
</div>
<div class="col-md-3">
<label>Cluster:</label>
<select class="form-control select2" name="cluster_id[]" id="cluster_id">
<option>All</option>
<?php foreach ($clusters as $cluster){ ?>
<option><?php echo $cluster->cluster_name; ?></option>
<?php } ?>
</select>
</div>
<div class="col-md-3">
<label>Type:</label>
<select class="form-control" name="property_type" id="prop_type">
<option>All</option>
<?php if ($property_type) { foreach ($property_type as $type) {?>
<option><?= $type->property_type_name;?></option>
<?php } } ?>
</select>
</div>
<div class="col-md-3">
<label>Stage:</label>
<select class="form-control" name="property_status" id="prop_status">
<option>All</option>
<?php foreach ($property_stage as $stage) { ?>
<option><?= $stage->stage_name; ?></option>
<?php } ?>
</select>
</div>
</div>
<div class="panel-body">

我想用面积和杂波过滤数据，然后输入和分期。

更多细节，我在这里添加控制器和模型代码：

"data" => $data

echo json_encode($output);
}
我浏览了这个链接Data-Tables，但它只给出了表格中列的结果，我没有在表格中显示区域列。
Edit_2：
在谷歌搜索时，我得到了这个链接，Search API (regular expressions)，Data table specific column filter with multi select drop down ，Individual column searching (select inputs) ，我正在尝试实现这样的结果，但使用下拉框。
欢迎任何形式的帮助。提前致谢。
【问题讨论】：
-
你可以为它创建一个小提琴吗？
-
这看起来很有趣，我可能有一些时间在周末看看它，但我猜你正在搜索多个列，搜索变得越来越精细......你在使用服务器端数据呢？我猜你也必须在他们的父母改变时清除孩子的选择框。一个 JS Fiddle 也会很有帮助。
-
@annoyingmouse 是的，我正在使用服务器端数据。实际上我想要一个级联下拉过滤，每个下拉列表中都有多个选择选项（主要来自集群选择框）。我用谷歌搜索了很多，但没有成功。

您能否发布您的 RENDERED html 而不是带有所有
php代码的那个，那 sn-p 怎么样？ ;) -
对不起，也许我在阅读您的问题时迷路了，但是，cluster 列在哪里，我看到 area，type和 status 但对于我的生活，我找不到代表 cluster 的列
