Can I have a click and keyboard handler for RaphaelJS' canvas events?
I am new to RaphaelJS. I am trying to add click listener and keyboard listener to the canvas with no success. Can someone please explain how to use click listener and keyboard listene开发者_JAVA技巧r on Raphael. A small example will be of great help.
Thank you.
Here is a click and mouseover example, you can use more jQuery in there to simplify it but I just wanted to use the document ready function. Shouldn't be too much to add a keyboard event in there:
<html>
<head>
<script type="text/javascript" src="http://github.com/DmitryBaranovskiy/raphael/blob/master/raphael-min.js?raw=true"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
var paper = new Raphael(document.getElementById('canvas_container'), 500, 500);
var circ = paper.circle(250, 250, 40);
circ.node.onmouseover = function()
{
this.style.cursor = 'pointer';
};
circ.node.onclick = function()
{
circ.animate({opacity: 0}, 2000, function()
{
this.remove();
});
}
});
</script>
<style type="text/css">
#canvas_container
{
width: 500px;
border: 1px solid #aaa;
}
</style>
</head>
<body>
<div id="canvas_container"></div>
</body>
</html>
加载中,请稍侯......
