Introduction to jQuery hide()
jQuery incorporates the feature to hide the selected html element in an easy and fast way. Hide() method is one of the jQuery functions to remove the selected element(s) along with child elements, associated events, and data. In other way, it removes a callback or list of callbacks from a callback list. Its functionality is also extended to apply a filter to choose specific elements for which associated data will be removed on the execution of the method.
Syntax:
$(selector).hide([Input parameter values])

| Queue | To decide about the arrangement of the animation effects in the queue. | True | String /Boolean | 1.0 |

Examples of jQuery hide()
Given below are examples of jQuery hide():
Example #1 – Without Using any parameter (with default values).
The hide() method can be used without any input argument value being provided. In this case, it executes the default values.
Code:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(document).ready(function(){
$(".btn1").click(function(){
$("p").hide();
});
});
});
</script>
</head>
<body style="background-color:blanchedalmond;">
<h3 style="font-family: Arial, Helvetica, sans-serif;">'hide()' method is used without paramter</h3>
<p style="font-family: Arial, Helvetica, sans-serif;">This paragraph is coded with p element.</p>
<button class="btn1">Hide 'p' element</button>
</body>
</html>
Output:
Before hide() method is called:
After hide() method is called:
Example #2 – With ‘Duration’ parameter.
The duration parameter is used with the method to regulate how long it should consume for the process to take place. The keyword “slow” or “fast” can be used that stands for 200 milliseconds and 600 milliseconds respectively. Any numeric can also be used as a duration value.
Code:
<html lang="en">
<head>
<meta charset="utf-8">
<style>
span {
padding: 3px;
float: left;
font-family: Georgia, 'Times New Roman', Times, serif;
font-size: larger;
}
</style>
<script src="https://code.jquery.com/jquery-3.4.1.js"></script>
</head>
<body style="background-color:blanchedalmond;">
<div>
<span>This</span> <span>example</span> <span>is</span>
<span>written</span> <span>to</span> <span>hide</span>
<span>elements</span>
</div>
<br>
<br>
<button id="hider">Click here to Hide</button>
<button id="shower">Click here to Show</button>
<script>
$( "#hider" ).click(function() {
$( "span:last-child" ).hide( "fast", function() {
// Use arguments.callee so we don't need a named function
$( this ).prev().hide( "fast", arguments.callee );
});
});
$( "#shower" ).click(function() {
$( "span" ).show( 3000 );
});
</script>
</body>
</html>
Output:
Before hide() method is called:
After hide() method is called:
The span element is animated to be hidden fast i.e each animation will be completed within 200 milliseconds. The animation on each element will get completed sequentially.
Example #3 – With ‘easing’ parameter
The speed of the hiding process at a different instance of time is regulated by the easing parameter. In order to set the speed of the hiding, the process is slower at the beginning and at the end, faster in the middle, the “Swing” keyword is used as the parameter value. Otherwise, to have a constant speed for throw-out the process, the key word “Linear” is used.

Thus hide() method supports customization in the hiding process for the matched element. The effectiveness of any website can be enhanced significantly by the use of this method by adding attractive animation effects. This method can be used with text as well as images, links, etc.
Additional Note:
- This method is equivalent to .css( “display”, “none” ).
- The method hide() functions as an animation method, when a duration, or easing parameter, or a “complete” function is provided. The .hide() method animates the width, height, and opacity of the matched elements simultaneously.
- Remove() and Hide() exhibits similar animation behavior on UI . But they differ from the internal mechanism. Hide() sets the ‘Display’ CSS property of the matched element to value ‘None’ whereas Remove() removes the matched element from DOM completely.
