加載並單擊隱藏/顯示div

Question

我想做的是在加載時隱藏除＃p0以外的所有段落。 另外，如果用戶單擊同級跨度，我想顯示一個段落，並隱藏所有其他段落

<ul>
   <li>
      <h1>
        <span id="span0">Lorem</span>
        <p id="p0">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span1">Lorem2</span>
        <p id="p1">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span2">Lorem3</span>
        <p id="p2">Lorem ipsum dolor sit amet,</p>
      </h1> 
   </li>
...

Answer 1

 $('p:not("#p0")').hide(); $('span').on('click',function() { $('p').hide(); $(this).next('p').show(); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <ul> <li> <h1> <span id="span0">Lorem</span> <p id="p0">Lorem ipsum dolor sit amet,</p> </h1> </li> <li> <h1> <span id="span1">Lorem2</span> <p id="p1">Lorem ipsum dolor sit amet,</p> </h1> </li> <li> <h1> <span id="span2">Lorem3</span> <p id="p2">Lorem ipsum dolor sit amet,</p> </h1> </li> </ul> 

如果您希望將其與頁面上其他p / span分開，則可以使用'prefixed-by'屬性選擇器（ ^= ） ...

 $('p[id^="p"]:not("#p0")').hide(); $('span[id^="span"]').on('click',function() { $('p[id^="p"]').hide(); $(this).next('p[id^="p"]').show(); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <ul> <li> <h1> <span id="span0">Lorem</span> <p id="p0">Lorem ipsum dolor sit amet,</p> </h1> </li> <li> <h1> <span id="span1">Lorem2</span> <p id="p1">Lorem ipsum dolor sit amet,</p> </h1> </li> <li> <h1> <span id="span2">Lorem3</span> <p id="p2">Lorem ipsum dolor sit amet,</p> </h1> </li> </ul> 

Answer 2

$('#p0').hide();

$('span').on('click',function() {
    $('p').hide();
    $(this).next('p').show();
});

<ul>
<li>
  <h1>
    <span id="span0" class="spanclick">Lorem</span>
    <p id="p0" class="par1">Lorem ipsum dolor sit amet,</p>
  </h1>
</li>
<li>
  <h1>
    <span id="span1" class="spanclick">Lorem2</span>
    <p id="p1" class="par1">Lorem ipsum dolor sit amet,</p>
  </h1>
</li>
<li>
  <h1>
    <span id="span2" class="spanclick">Lorem3</span>
    <p id="p2" class="par1">Lorem ipsum dolor sit amet,</p>
  </h1> 
</li>


<script>
$(document).ready(function () {
  $(".par1").hide();
  $(".spanclick").click(function(){
    $(".par1").toggle();

  });
});
