How to Use the delay() Method in jQuery
jQuery’s delay() method sets a timer for executing the next item. This tutorial demonstrates how to use the delay() method in jQuery.
jQuery delay() Method
The delay() is a built-in function in jQuery used to delay the execution of a particular item. This method is the best choice for providing a delay between the queued jQuery effects.
The syntax for this method is:
$(selector).delay(parameter1, parameter2);
Where:
- The
selectorcan be the id, class, or element name. - The
parameter1is the speed of the delay, which can be in milliseconds, slow or fast. - The
parameter2is optionally used to specify the queue name; the default isfx, which is the standard effects queue.
Let’s try examples to show the effect of the delay() method in jQuery:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("#box1").delay("slow").fadeIn();
$("#box2").delay("fast").fadeIn();
$("#box3").delay(1000).fadeIn();
$("#box4").delay(2000).fadeIn();
$("#box5").delay(3000).fadeIn();
$("#box6").delay(4000).fadeIn();
});
});
</script>
</head>
<body>
<h1>jQuery delay() method.</h1>
<p>Click the button to show the delay effect. Color boxes will fade in on the click with a delay</p>
<button>Click Here</button>
<br><br>
<div id="box1" style="width : 50px; height : 50px; display : none; background-color : pink;"> slow </div> <br>
<div id="box2" style="width : 50px; height : 50px; display : none; background-color : green;"> fast </div> <br>
<div id="box3" style="width : 50px; height : 50px; display : none; background-color : blue;"> 1 second </div> <br>
<div id="box4" style="width : 50px; height : 50px; display : none; background-color : violet;"> 2 seconds </div> <br>
<div id="box5" style="width : 50px; height : 50px; display : none; background-color : yellow;"> 3 seconds </div> <br>
<div id="box6" style="width : 50px; height : 50px; display : none; background-color : purple;"> 4 seconds </div> <br>
</body>
</html>
In the code above, the color boxes will fade in with the given delay. See output:
Let’s try another example in jQuery, which will animate the div based on the delay() method. See the example:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"> </script>
<script>
$(document).ready(function() {
$("#DemoButton").click(function() {
$("#DemoDiv").delay("fast").animate({
width: "250px",
padding: "35px"
});
$("#DemoDiv").delay("slow").animate({
width: "350px",
padding: "55px"
});
$("#DemoDiv").delay(1000).animate({
width: "275px",
padding: "50px"
});
$("#DemoDiv").delay(2000).animate({
width: "500px",
padding: "60px"
});
$("#DemoDiv").delay(3000).animate({
width: "200px",
padding: "40px"
});
});
});
</script>
<style>
#DemoDiv {
background-color : lightblue;
width : 200px;
height : 100px;
font-size : 30px;
padding : 10px;
display : block;
}
</style>
</head>
<body>
<div id="DemoDiv">Hello, This is Delftstack.com</div>
<button id="DemoButton">Click Here</button>
</body>
</html>
The code above will change the height and width of the div based on the given time delay. See output:
