jQuery Effects: Hide/Show Image

jQuery hide() and show()

In jQuery, you can use the .hide() and .show() methods to control the visibility of HTML elements on a webpage.

  1. The .hide() method is used to hide elements by setting their CSS display property to "none," effectively making them invisible.
  2. The .show() method is used to display hidden elements, reverting their CSS display property to its original state.

These methods are commonly used for creating interactive and dynamic web pages, allowing you to control when and how elements are displayed to users.

$('#btn1').click(function(){ $('#imgDiv').show(); }); $('#btn2').click(function(){ $('#imgDiv').hide(); });
<div id="imgDiv"> <img src="myImg.jpg" alt="Show/Hide Image" /> </div>

jQuery toggle() method

The jQuery toggle() method is used to toggle between the hide() and show() methods for the selected elements. It provides a simple way to toggle the visibility of elements on a web page.

Here's a brief explanation of how it works:

  1. When you call toggle(), it checks the current visibility state of the selected element(s).
  2. If the element(s) is currently visible (displayed), it hides it using the hide() method.
  3. If the element(s) is currently hidden (not displayed), it shows it using the show() method.
$('#btn1').on("click",function(e){ $('#myImg').toggle('slow'); });
<img src="myImg.jpg" alt="Show/Hide Image" id="myImg"/>

Note:

The .toggle() method had its event-based signature deprecated in jQuery 1.8 and subsequently removed in jQuery 1.9. However, jQuery still offers an animation-oriented .toggle() method that facilitates the toggling of element visibility, incorporating smooth transitions like sliding elements up or down. The specific behavior of this method—whether it functions as an animation or event handler—is determined by the arguments provided during its invocation, making it a versatile tool for creating interactive and visually appealing elements in web development.

Conclusion

jQuery provides the .hide() and .show() methods, which allow you to easily hide and show HTML elements, including images, on a webpage. These methods are commonly used to create interactive effects and control element visibility in web development.
