I need to find a way where I can dynamically change the source of a processing script inside an HTML document.
This is the embedded script which works fine:
<script type='application/processing' src='sketch.txt' id="applet">
</script>
Now I try to change the source:
$('#applet').attr('src', 'sketch2.txt');
alert($('#applet').attr('src'));
The alert shows that the source was changed to 'sketch2.txt' but the applet still remains the same. I think I need to refresh the script in some way.
Thank you in advance for any help!
I believe you have to manually attach each proc to the canvas, instead of just changing the the source file. This worked here:
function first_call(processing) {
processing.size(300,300);
processing.background(100);
var called = false;
processing.draw = function() {
if (!called) { processing.println("called #1"); called = true; }
}
}
function second_call(processing) {
processing.size(400,400);
processing.background(200);
var called = false;
processing.draw = function() {
if (!called) { processing.println("called #2"); called = true; }
}
}
var canvas = document.getElementById('canvas1');
var processingInstance = new Processing(canvas, first_call);
var processingInstance = new Processing(canvas, second_call);
