# event.preventDefault()

## event.preventDefault ( ) Returns: undefined version added: 1.0

Description: If this method is called, the default action of the event will not be triggered.

For example, clicked anchors will not take the browser to a new URL. We can use `event.isDefaultPrevented()` to determine if this method has been called by an event handler that was triggered by this event.

## Examples:

#### Example: Cancel the default action (navigation) of the click.

    <!doctype html>
    <html lang="en">
    <head>
      <meta charset="utf-8">
      <title>css demo</title>

      <script src="//code.jquery.com/jquery-1.10.2.js"></script>
    </head>
    <body>

    <a href="http://jquery.com">default click action is prevented</a>
    <div id="log"></div>

    <script>

    $( "a" ).click(function( event ) {
      event.preventDefault();
      $( "<div>" )
        .append( "default " + event.type + " prevented" )
        .appendTo( "#log" );
    });
