Question

我期待值1和2，但它返回null。知道为什么会这样吗？

$(function() {

  $('.agent_rows').each(function() {
    console.log($(this).find('input[name="associatedAgentId"]').val())
  })

});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="1">
</div>

<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="2">
</div>

Answer 1

您设置的属性不正确。它应该是value而不是属性中的val：

 <div class="agent_rows">
   <input type="hidden" name="associatedAgentId" value="1">
 </div>

 <div class="agent_rows">
   <input type="hidden" name="associatedAgentId" value="2">
 </div>

Answer 2

应该是value而不是val：

<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="1">
</div>

<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="2">
</div>

工作代码段

$(function() {
  $('.agent_rows').each(function() {
    console.log($(this).find('input[name="associatedAgentId"]').val())
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="1">
</div>

<div class="agent_rows">
  <input type="hidden" name="associatedAgentId" value="2">
</div>

用于获取每个输入值
