jQuery Effect: jQuery Code to get a single element from a selection

jQuery Effect : Exercise-7 with Solution

Write a jQuery Code to get a single element from a selection.
Sample Data :

HTML code:

<body>
<ui>
<li>Html Tutorial</li>
<li>Mongodb Tutorial</li>
<li>Python Tutorial</li>
</body>

Solution:

HTML Code :

<!DOCTYPE html>
<html>
<head>
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
  <meta charset="utf-8">
  <title>Write a jQuery Code to get a single element from a selection</title>
</head>
<body>
<p> Click this paragraph to see it fade.</p>
</body>
</html>

JavaScript Code :


$( "p:first" ).click(function() {
  $( this ).fadeTo( 500, 0.40 );
});

Note : In jQuery .on( events [, selector ] [, data ], handler ) method is used to attach an event handler function for one or more events to the selected elements.. It has the following parameters :

  • events : Space-separated event (one or more) types and optional namespaces, such as "click" or "keydown.myPlugin". [Type: String]
  • selector : Filter the descendants of the selected elements that trigger the event. [Type: String]
  • data : Data to be passed to the handler in event.data when an event is triggered. [Type: Anything]
  • handler : A function to execute when the event is triggered. [Type: Function( Event eventObject [, Anything extraParameter ] [, ... ] )]
