JavaScript Event - Dblclick
/skill level/
/viewed/
This code was written based on a template by John Resig. The original can be found at John Resig's addEvent function website.
The code, and the template, are referred to in Webmonkey's JavaScript Events reference page. In this example, the onDblClick event fires whenever a mouse button is clicked twice within a time frame determine by the operating system (a double-click). If attached to a specific object (such as the div in the example below), the event only fires if the mouse is double-clicked within the bounds of that object.
This code is in a wiki. If you have any advances to make to the original tutorial and code, please feel free to contribute.
The Code

<script>
// addEvent function by John Resig:
// http://ejohn.org/projects/flexible-javascript-events/
function addEvent( obj, type, fn ) {
if ( obj.attachEvent ) {
obj['e'+type+fn] = fn;
obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
obj.attachEvent( 'on'+type, obj[type+fn] );
} else
obj.addEventListener( type, fn, false );
}
</script>

<!-- HTML for example event goes here -->
<div id="mydiv" style="border: 1px solid black; width: 100px; height: 100px; margin-top: 10px;"></div>
<script>
// Script for example event goes here
addEvent(document.getElementById('mydiv'), 'dblclick', function(event) {
display_short('double-clicked');
});
function display_short(str)

clearTimeout();
document.getElementById('mydiv').innerHTML = str;
if (str != '')
setTimeout("display_short('')", 1000);
}
