How to Create Show/Hide Effect in Image SlideShow Using JQuery

The fadeOut() effect presented on the post "How to create Fade Effect in Image Slideshow using JQuery" which I have already posted, makes elements invisible but retains space for them in the document layout.

The hide() method, by contrast, removes the elements from the layouts as if the CSS display property was set to none. When invoked with no arguments, hide() and show() simply hide or show the selected elements immediately. With a duration argument, however, they animate the hiding or showing process. hide() shrinks an element's width and height to 0 at the same time that it reduces the element's opacity to 0. show() reverses the process.

toggle() changes the visibility state of the elements, it is invoked on, if they are hidden, it calls show(), and it they are visible, it calls hide(). As with show() and hide(), you must pass a toggle() to get an animated effect. Passing true to toggle() is the same as calling show() with no arguments. Note also that if you pass two or more function arguments to toggle() it registers event handlers.

Here is an example that invokes methods for show/hide effect animation. The first image has show() effect animation, second image has hide() effect animation and the third animation has toggle() effect animation.

$("#img1").show(2000);
$("#img2").hide(3000);
$("#img3").toggle(1000);

Here are some examples to show show(), hide() and toggle() effects using jQuery.

Example of show() Effect 


<script>
  $(document).ready(function(){
    $(#btn1).click(function () {
      $("#img1").show(2000);
    });
  });
  </script>

<input type=button id="btn1" value="Start Show"/>
<img id="img1" src="img1.jpg">



Example of hide() Effect


<script>
  $(document).ready(function(){
    $(#btn2).click(function () {
      $("#img2").hide(3000);
    });
  });
  </script>

<input type=button id="btn2" value="Start Hide"/>
<img id="img2" src="img2.jpg">



Example of toggle() Effect 


<script>
  $(document).ready(function(){
    $(#btn3).click(function () {
      $("#img3").toggle(1000);
    });
  });
  </script>






<input type=button id="btn3" value="Start Toggle"/>
<img id="img3" src="img3.jpg">
