What is the difference between jQuery.show() and jQuery.hide()?
jQuery show() method
The show( speed, [callback] ) method shows all matched elements using a graceful animation and firing an optional callback after completion.
Here is the description of all the parameters used by this method −
- speed − A string representing one of the three predefined speeds ("slow", "normal", or "fast") or the number of milliseconds to run the animation (e.g. 1000).
- callback − This is optional parameter representing a function to call once the animation is complete.
Example
You can try to run the following code to learn how to work with show() method:
<html>
<head>
<title>The jQuery Example</title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#show").click(function () {
$(".mydiv").show( 100 );
});
$("#hide").click(function () {
$(".mydiv").hide( 100 );
});
});
</script>
<style>
.mydiv {
margin:10px;
padding:12px;
border:2px solid #666;
width:100px;
height:100px;
}
</style>
</head>
<body>
<div class = "mydiv">
This is a SQUARE.
</div>
<input id = "hide" type = "button" value = "Hide" />
<input id = "show" type = "button" value = "Show" />
</body>
</html>
