我正在销售产品,我使用AJAX根据从下拉列表到另一个下拉列表的选择来捕获数据。当我动态创建一个字段时,它只能工作一次,我希望它能工作N次。
这是我的HTML& PHP代码:
<div class="row col-md-12 mrg-top-20">
<h4 class="card-title" style="color:#ff0033">Sales Details</h4><br>
<div class="col-md-12"></div>
<div class="row col-md-12" data-duplicate="add">
<div class="col-md-4">
<label>Select <strong>Installation Date</strong></label>
<div class="form-group">
<div class="timepicker-input input-icon form-group">
<i class="ti-time"></i>
<input type="text" name="ins_date" class="form-control datepicker-1" placeholder="Datepicker" data-provide="datepicker">
</div>
</div>
</div>
<div class="col-md-4" id="sel_dynamic">
<div class="form-group">
<label>Select <strong>Manufacturer</strong></label>
<select name="manu" id="manu" class="form-control" style="width:100%">
<option disabled="disabled" selected="selected">Select Manufacturer</option>
<?php
$data = mysqli_query($conn,"SELECT * FROM manufacturer_details");
while($itemcat = mysqli_fetch_array($data))
{
?>
<option value="<?php echo $itemcat['MANUFACTURER_ID']; ?>"><?php echo $itemcat['MANUFACTURER_NAME'];?></option>
<?php
}
?>
</select>
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label>Select <strong>Modal</strong></label>
<select name="modal" id="modal" class="form-control" style="width:100%">
<option value="" selected disabled="disabled">Select Modal...</option>
</select>
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label>Ser<strong>ial</strong></label>
<input type="text" name="serial" placeholder="Enter Serial No" class="form-control">
</div>
</div>
<div class="col-md-4">
<label>Select <strong>AMC Start Date</strong></label>
<div class="form-group">
<div class="timepicker-input input-icon form-group">
<i class="ti-time"></i>
<input type="text" name="amc_date" class="form-control datepicker-1" placeholder="Datepicker" data-provide="datepicker" data-date-format="mm/dd/yyyy">
</div>
</div>
</div>
<div class="col-md-4">
<label>Select <strong>AMC End Date</strong></label>
<div class="form-group">
<div class="timepicker-input input-icon form-group">
<i class="ti-time"></i>
<input type="text" name="amc_edate" class="form-control datepicker-1" placeholder="Datepicker" data-provide="datepicker" data-date-format="mm/dd/yyyy">
</div>
</div>
</div>
</div>
<div>
<input type="button" id="add" data-duplicate-add="add" class="btn btn-info" value="+"/>
</div>
<div >
<input type="button" data-duplicate-remove="add" class="btn btn-info" value="-"/>
</div>
</div>
以下是每次调用Ajax的My Js脚本
<script type="text/javascript">
$(document).ready(function()
{
$("#sel_dynamic").on("change","#manu",(function() //just try to use on change
{
var id = $("#manu").val();
var dataString = 'id='+ id;
$.ajax
({
type: "POST",
url: "ajax_modal.php",
data: dataString,
cache: false,
success: function(html)
{
$("#modal").html(html);
}
});
});
});
</script>
这是我的Ajax文件
<?php
include('script/db.php');
if($_POST['id'])
{
$id=$_POST['id'];
$sql=mysqli_query($conn,"select * from modal_details where MANUFACTURER_ID='".$id."'");
?>
<option selected disabled="disabled">Select Modal Name</option>
<?php
while($row = mysqli_fetch_assoc($sql))
{
$id = $row['MODAL_ID'];
$data = $row['MODAL_NAME'];
echo '<option value="'.$id.'">'.$data.'</option>';
}
}
?>
每当我动态创建一个新字段时,我的AJAX就无法正常工作。

Try this :
<script type="text/javascript">
$(document).ready(function()
{
$(document).on('change','#manu',function()
{
var id = $("#manu").val();
var dataString = 'id='+ id;
$.ajax
({
type: "POST",
url: "ajax_modal.php",
data: dataString,
cache: false,
success: function(html)
{
$("#modal").html(html);
}
});
});
});
</script>

评论清楚表明您正在复制表单。我认为您的页面上有重复的ID,您的jQuery事件将不再起作用。 ID只能出现一次。
看看这里: Clone form and increment

Add the class to select as shown below:
<select name="manu" id="manu" class="form-control manuClass" style="width:100%">
And use the below script
<script type="text/javascript">
$(document).ready(function()
{
$(document).on('change','.manuClass',function()
{
var id = $(this).val();
var dataString = 'id='+ id;
$.ajax
({
type: "POST",
url: "ajax_modal.php",
data: dataString,
cache: false,
success: function(html)
{
$(this).parent().parent().next().children().children("#modal").html(html);
}
});
});
});
</script>
