JQuery Focus Selector Example

May 20, 2014 //  by Krishna Srinivasan//  Leave a Comment

JQuery focus selector selects the element that has focus. The focus selector used for styling an element that accepts keyboard input focus or other user inputs such as activating with the mouse. It is applied when an element accepts focus from user. It works with any selector events and focuses the element when it gets triggered. It is written as “:focus”, means it is recommended that it must start with colon and tag name.

JQuery Focus Selector Syntax

$(“:focus”)

JQuery Focus Selector Example

<!doctype html>
<head>
<title>JQuery Focus Selector</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Focus Selector Example</h2>
<style>
   input:focus:hover
   {
      background-color:orange;
      border:medium dotted green;
   }
</style>
<script>
   $(document).ready(function(){
      $("input").focus();
   });
</script>
<body>
<form>
   Name:<input type="text" name="uname">
</form>
</body>
</html>
  • As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
  • $(“input”).focus(); line defines focus selector which focuses the element when it’s get triggered from user inputs such as keyboard input or by using with the mouse.
  • When we run the above script, we will get input type element which uses mouse hover property. When we keep mouse on the input text element, the background color will change to orange color and displays border with medium dotted green color.
