javascript - 如何使点击事件与动态生成的 html 元素一起工作

Question

单击添加更多链接时，会动态生成一个div，用于添加其他文本输入和添加更多链接。此动态插入的添加更多链接不响应点击事件。尽管每个动态插入的链接都有一个唯一的 id，并且单击事件通过 Jquery on() 方法 使用“委托(delegate)”绑定(bind)，但动态插入的链接在单击时无法通过添加更多字段来工作。这是jsbin整个代码如下:

Javascript:

<script type="text/javascript">
  $(document).on("ready", function(){

    return $(".add_people_filter").on("click", function(event){

      event.preventDefault();

      var time = new Date().getTime();
      var dynamicallyCreatedDiv = document.createElement("div");
      dynamicallyCreatedDiv.id = time;

      var peopleFilterContainerDiv = $("#people_filter_container");
      peopleFilterContainerDiv.append(dynamicallyCreatedDiv);
      var getHtmlForDynamicDiv = $(".people_filter").html();
      var theNewDiv = $(dynamicallyCreatedDiv);
      theNewDiv.append(getHtmlForDynamicDiv);

      var AddUniqueIdToLinK = time * 2;
      var x = time * 3;
      $(this).attr('id', AddUniqueIdToLinK);
      theNewDiv.find("a:last").attr('id', x);

      return theNewDiv;
   });
 });
</script>

html:

<div id="people_filter_container">
  <div class="people_filter"  >
    <input type="text" name="firstname" placeholder="add name" >
    <a href="#" data-behavior="add_people_filter" class="add_people_filter"> add more</a> 
    <br> <br>
  </div>

</div>

改变它:

return $("body").on("click",".add_people_filter", function(event)
{
        ...... YOUR CODE      
});
