The aim of this example is to show you how to use the jQuery setTimeout() method.
Sometimes we need to execute a javascript code after some seconds, the jQuery setTimeout() method can be used for this purpose.
This method takes two parameters:
- The first is the javascript that need to be executed.
- The second is the delay time in milliseconds.

1. HTML
First of all you need to create a simple html document.

<!DOCTYPE html> <html> <head> <title>jQuery setTimeout Example</title> <script src="jquery-2.1.4.min.js"></script> </head> <body> </body> </html>
2. jQuery setTimeout examples
2.1 Call a method after 2 seconds
Let’s add the following simple html code.
<div id="data" style="border:1px solid #eee;height:50px;width:300px;">Loading...</div>
In the following jQuery code, the line 3 will set timer to call setData() method after 2000 milliseconds. As you can notice, it is easy to delay running any javascript code by using jQuery setTimeout() method.
<script type="text/javascript">
$(function () {
setTimeout("setData()",2000);
});
function setData(){
jQuery("#data").html("setData() method is called after 2 seconds");
}
</script>
The result in the browser would be:
2.2 Hiding a DIV after 3 seconds
Let’s add the following simple html code.
<div style="border:1px solid #f00;height:50px;width:300px;background-color:#e0e0e"> <div id="container"> This div will be hide after 3 seconds </div> </div>
As you can notice, in the following example the first setTimeout() method’s argument is an anonymous method that will be called after 3 seconds.
<script type="text/javascript">
$(function () {
setTimeout(
function(){
jQuery("#container").hide();
}
,3000);
});
</script>
The result in the browser would be:
3. Conclusion
