有下拉列表，从列表中选择任何值后，它应该添加新行，例如:

现在我有:

Javascript

  $.fn.optionTest = function(opts) {
    var option = $.extend({}, $.fn.optionTest.defaults, opts);


    $(this).change(function() {

      }
      var val = $(this).val();
      if ($.fn.optionTest.isArray(val)) {
        $.fn.optionTest.parseArray(val, option);
      } else {
                var label =$(this).children("option:selected").eq(0).text();
        $.fn.optionTest.parseContent(val, option, label);
      }

      $('.' + option.removeLinkOptions.class).click(function(event) {
        $.fn.optionTest.removeRow(this, option);
        event.preventDefault();

      });

<div class="endorsements" id="action2"> 

</div>
</fieldset>

目前它生成的结构如下:

<div>
   <ul>
      <li>
         <input></input>  
      </li>
      <li>
         <input></input>  
      </li>
      <li>
         <input></input>  
      </li>
      <li>
         <input></input>  
      </li>
      <li>
         <input></input>  
      </li>
      <li>
         <input></input>  
      </li>
   </ul>
</div>

但是我需要这样的东西:

<ul class="endorsements" id="personal-details3">
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>   
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>
   <li>
      <ul class="column">
         <li><input></input></li> 
      </ul>
   </li>
</ul>

如您所见，这个结构是通过 Javascript 创建的，而不是 HTML，所以我无法成功理解。

我试过替换这个:

var CertNo = $.fn.optionTest.createColumn($("<input>", CertNoData));

喜欢:

var CertNo = $.fn.optionTest.createColumn($("<ul><li><input>", CertNoData));

但在这种情况下，我得到的是空文本字段，没有(placeholder、id、name ..etc)。

我创建了 JS FIDDLE . Endorsements 部分是通过 HTML 生成的，例如它应该是什么样子并且应该修改 Licenses & Certificates 字段(尝试从下拉列表中选择任何值以生成字段) .

最佳答案

Updated Fiddle

你可以添加两个变量:

var start_by = "<li><ul class='column'><li>";
var end_by = "</li></ul></li>";

将它添加到每个字段，如下所示:

var STCWCode = $.fn.optionTest.createColumn($("<input>", STCWCodeData));
STCWCode = $(start_by+$(STCWCode).html()+end_by);

完整代码如下:

var STCWCode = $.fn.optionTest.createColumn($("<input>", STCWCodeData));
STCWCode = $(start_by+$(STCWCode).html()+end_by);

var CertNo = $.fn.optionTest.createColumn($("<input>", CertNoData));
CertNo = $(start_by+$(CertNo).html()+end_by);

var PlaceofIssue = $.fn.optionTest.createColumn($("<input>", PlaceofIssueData));
PlaceofIssue = $(start_by+$(PlaceofIssue).html()+end_by);

var DateofIssue = $.fn.optionTest.createColumn($("<input>", DateofIssueData));
DateofIssue = $(start_by+$(DateofIssue).html()+end_by);

var DateofExpire = $.fn.optionTest.createColumn($("<input>", DateofExpireData));
DateofExpire = $(start_by+$(DateofExpire).html()+end_by);

var from = $.fn.optionTest.createColumn($("<input>", fromData));
from = $(start_by+$(from).html()+end_by);

var to = $.fn.optionTest.createColumn($("<input>", toData));
to = $(start_by+$(to).html()+end_by);

var removeRow = $.fn.optionTest.createColumn($("<img>", options.removeLinkOptions).attr("src",""));
removeRow = $(start_by+$(removeRow).html()+end_by);    

要使用新的 DOM 调整删除操作，它应该以类 .endorsements 的父 ul 为目标:

$.fn.optionTest.removeRow = function(elem, options) {
    var row = $(elem).closest(".endorsements");
    row.remove();
    $.fn.optionTest.updateRowIndex(options);
};

要使新行垂直，您可以添加以下 CSS 规则:

#action2 > ul{
    display: block;
    width: 100%;
}

#action2 > ul > li{
    width: 16.66%;
    display: inline-block;
}

#action2{
  display: block;
}

希望这对您有所帮助。

关于javascript - 通过 Javascript 添加行后指定 ul li 结构，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35670338/
