javascript - 在 Jquery 中为文本和日历控件生成 ID

Question

每当我点击 .add 类时，我想为输入类型 text 生成 Id's。目前，每当我点击 .add 类时，它都会为每个输入控件生成具有相同名称的 ID。所以在添加数据时它不能正常工作。

那么，每当我点击 .add 类时，我应该如何为每个文本生成 ID。请提出建议。

这是生成的内容。

Generated HTML

$('.add').on('click', function() {
  var $tr = $(this).closest('tr');
  var $tr2 = $tr.clone(true, true);
  $tr2.find(".vendorName").children('label').remove();
  $tr2.find(".vendorFromDate").children('label').remove();
  $tr2.find(".vendorToDate").children('label').remove();
  $tr2.find(".vendorName").children().unwrap();
  $tr2.find(".vendorFromDate").children().unwrap();
  $tr2.find(".vendorToDate").children().unwrap();
  $tr2.insertAfter($tr);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<tr>
  <td>
    <div class="row noPadding vendorForm">
      <div class="vendorDaterow">
        <div class="vendorName" id="dvVendorNameData">
          <label>SP Vender Name</label><span><input type="text" name="nmVendorData" id="txtVendorName1" /></span>
        </div>
        <div class="vendorFromDate">
          <label>From Date</label><span class="datepicker"><input type="text" name="nmVendorData" id="spFromDate1" /><i class="fa fa-calendar" aria-hidden="true"></i></span>
        </div>
        <div class="vendorToDate">
          <label>To Date</label><span class="datepicker"><input type="text" name="nmVendorData" id="spToDate1" /><i class="fa fa-calendar" aria-hidden="true"></i></span>
        </div>
      </div>
      <div class="add">
        <i class="fa fa-plus" aria-hidden="true"></i>
      </div>
      <i class="max">(Maximum 5 Vendors)</i>

    </div>
  </td>
</tr>

请建议我应该如何生成动态 ID。

检查这个

(function () {
  var toAddCloneCount = 2;

$('.add').on('click', function() {
  var $tr = $(this).closest('tr');
  var $tr2 = $tr.clone(true, true);
  $tr2.find(".vendorName").children('label').remove();
  $tr2.find(".add").children().remove();
  $tr2.find(".vendorFromDate").children('label').remove();
  $tr2.find(".vendorToDate").children('label').remove();
  $tr2.find('#txtVendorName').prop('id', 'txtVendorName' + toAddCloneCount);
  $tr2.find('#spFromDate1').prop('id', 'spFromDate' + toAddCloneCount);
  $tr2.find('#spToDate1').prop('id', 'spToDate' + toAddCloneCount++);
  $tr2.insertAfter($tr);
});
})();

.vendorName,.vendorFromDate,.vendorToDate{
width:33%;float:left;}
