jQuery hide and show toggle div with plus and minus icon

问题

I have the code working for the show and hide the div. How would I add two different icons as a sprite image for when the show and hide are active?

For example: + icon for show me, then a - icon for hide me.

Here is the code, I have: http://jsfiddle.net/BLkpG/

$(document).ready(function(){
   $(".slidingDiv").hide();
   $(".show_hide").show();

    $('.show_hide').click(function(){
    $(".slidingDiv").slideToggle();
  });
});

Need to change image to the above when toggled to a + or -.

Thanks

Try something like this

jQuery

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

HTML

<a href="#" id="toggle_icon">+</a>

<div id="toggle_text" style="display: none">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
</div>

I would say the most elegant way is this:

<div class="toggle"></div>
<div class="content">...</div>

then css:

.toggle{
 display:inline-block;
height:48px;
width:48px;  background:url("http://icons.iconarchive.com/icons/pixelmixer/basic/48/plus-icon.png");
}
.toggle.expanded{
  background:url("http://cdn2.iconfinder.com/data/icons/onebit/PNG/onebit_32.png");
}

and js:

$(document).ready(function(){
  var $content = $(".content").hide();
  $(".toggle").on("click", function(e){
    $(this).toggleClass("expanded");
    $content.slideToggle();
  });
});

Toggle the text Show and Hide and move your backgroundPosition Y axis

LIVE DEMO

$(function(){ // DOM READY shorthand

    $(".slidingDiv").hide();

    $('.show_hide').click(function( e ){
        // e.preventDefault(); // If you use anchors
        var SH = this.SH^=1; // "Simple toggler"
        $(this).text(SH?'Hide':'Show')
               .css({backgroundPosition:'0 '+ (SH?-18:0) +'px'})
               .next(".slidingDiv").slideToggle();
    });

});

CSS:

.show_hide{
  background:url(plusminus.png) no-repeat;
  padding-left:20px;  
}

Here is a quick edit of Enve's answer. I do like roXor's solution, but background images are not necessary. And everbody seems to forgot a preventDefault as well.

$(document).ready(function() {
  $(".slidingDiv").hide();

  $('.show_hide').click(function(e) {
    $(".slidingDiv").slideToggle("fast");
    var val = $(this).text() == "-" ? "+" : "-";
    $(this).hide().text(val).fadeIn("fast");
    e.preventDefault();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" class="show_hide">+</a>

<div class="slidingDiv">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi. Nulla quis sem at nibh elementum imperdiet. Duis sagittis ipsum. Praesent mauris. Fusce nec tellus sed augue semper porta.

this works:

http://jsfiddle.net/UhEut/

CSS:

.show_hide {
    display:none;
}
.plus:after {
    content:" +";
}
.minus:after {
    content:" -";
}

jQuery:

$(document).ready(function(){
  $(".slidingDiv").hide();
  $(".show_hide").addClass("plus").show();
  $('.show_hide').toggle(
      function(){
          $(".slidingDiv").slideDown();
          $(this).addClass("minus");
          $(this).removeClass("plus");
      },
      function(){
          $(".slidingDiv").slideUp();
          $(this).addClass("plus");
          $(this).removeClass("minus");
      }
  );
});

HTML:

<a href="#" class="show_hide">Show/hide</a>

<div class="slidingDiv" style="display: block;">
Check out the updated jQuery plugin for doing this: <a href="http://papermashup.com/jquery-show-hide-plugin/" class="show_hide" target="_blank" style="display: inline;">jQuery Show / Hide Plugin</a>
</div>

in the CSS, instead of content:" +"; You can put an background-image (with background-position:right center; and background-repeat:no-repeat and maybe making the .show_hide displayed as block and give him a width, so that the bg-image is not overlayed by the link-text itself).

Here is an example of how to do it with an arrow instead of a + and -. This uses jQuery to change classes on the element, and CSS to style the arrow.

$(".toggleHide").click(function() {
  $(".elementToHide").slideToggle("fast");
  $(this).find("i").toggleClass("down up");
});

i {
  border: solid black;
  border-width: 0 5px 5px 0;
  display: inline-block;
  padding: 5px;
  -webkit-transition-duration: 1s;
  /* Safari */
  transition-duration: 1s;
}

.up {
  transform: rotate(-135deg);
  -webkit-transform: rotate(-135deg);
}

.down {
  transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<h3 class="toggleHide"><i class="down"></i></h3>
<aside class="elementToHide">
  Content to hide
</aside>

    var elem = $(this).next('.options');
    $('.options').not(elem).hide('fast');
    $('.SettingsTitle').not($(this)).parent().children("h3").children("a.toggle").children("img").attr('src', closeMenuImg);
    elem.toggle('fast');
    var targetImg = $(this).parent().children("h3").children("a.toggle").children("img").attr('src') === closeMenuImg ? openMenuImg : closeMenuImg;
    $(this).parent().children("h3").children("a.toggle").children("img").attr('src', targetImg);
  });

});
