单击链接时显示相关的div

Question

I created a ul containing li elements. I want to to slide down a div when a link in the same li is clicked.

The problem is when I click the link all div s are shown.

I use PHP for setting the id on each link.

The html code is here:

  <li class='post'>
    <div class='link'>
      <a href='#'id=". * Here is Post ID * ."></a>
    </div>
    <div class='slidedown'>//here is what I want to sliding</div>
  </li>

The jQuery code is here :

$(".link a").click(function(){

    var id_post = $(this).attr("id");

    $(".slidedown").slideDown("slow");

    return false;
});

Answer 1

Use .parent() to move up one parent. Since the container were looking for is the .post we'll have to move up 2 parents. Then we can find the child of it that is .slidedown and slide that one down with .slideDown()

$(".link a").click(function(){

    $(this).parent().parent().children('.slidedown').slideDown("slow");

});

Answer 2

You can do it even more easy:

jQuery

$('.link').on('click', function() {
    $(this).parent().find('.slidedown').slideDown('slow');
});

Or you use:

$('.link a').on('click', function() {
    $(this).closest('.slidedown').slideDown('slow');
});

Go to .closest() or .parent() at jQuery Docs to learn more.

Answer 3

Here's the code that works well:

$(".link").click(function(){
     $(this).siblings('.slidedown').slideDown('slow');
});

Answer 4

You can use parent() to move up a level and next() to target the next sibling:

$(".link a").click(function(){
  $(this).parent(".link").next(".slidedown").slideDown("slow");
  return false;
});

Or you can access the .post using closest() and target the .slidedown using find() or children() :

$(".link a").click(function(){
  $(this).closest(".post").find(".slidedown").slideDown("slow");
  return false;
});
