jQuery toggle on each? | 易学教程

问题

im using jquery to toggle some paragraphs. its pretty easy with just one paragraph but say i have a very generic setup. the second paragraph is initially hidden with css.

<p>some text</p>
<p>some more text</p>
<a href="#" class="more">read more</a>

<p>some text</p>
<p>some more text</p>
<a href="#" class="more">read more</a>

problem is that every time i click one of the "read more" links its shows the every second paragraph. i would just want it to show the second paragraph of the one clicked.

very new to jquery...

回答1:

First wrap your <p> tags in a div like so:

<div class='toggleable'>
  <p>some text</p>
  <p>some more text</p>
  <a href="#" class="more">more/less</a>
</div>

With some CSS:

.toggleable p {
  display: none;
}

Then the jQuery:

$('.toggleable a.more').click( function() {
  $(this).siblings('p').toggle();
} );

Should handle it.

There are other ways to solve this, of course. Maybe you could put the links outside of the div with the text and then do something like: $('.more').click( function() { $(this).prev().toggle(); } );... Plenty of approaches. Take a look at jQuery's DOM traversal methods.

sorry i think that i may have messed up the structure. its

<p>some text</p> 
<div class="bio> 
<p>some more text</p> 
</div> <a href="#" class="more">read more</a>  

<p>some text</p> 
<div class="bio> 
<p>some more text</p> 
</div> <a href="#" class="more">read more</a>

i need the first <p> to show always as sort of an experted. the second <p> and any subsequent <p> to only show on click of its specific <a> thanks for the quick response.
