paper.js处理程序不起作用

Question

I have a JavaScript file:

    var canvas = document.createElement('canvas');
    canvas.id = 'canvas1';
    canvas.width = 400;
    canvas.height = 400;
    canvas.resize;

    var e = document.createElement('script');
    e.type = '/text/javascript/';
    e.src = '/static/notebook/js/paper.js';

    var c = document.createElement('script');
    c.type = '/text/javascript/';
    c.src = '/static/notebook/js/mypaper.js';

My mypaper.js file has the following function that is built into paper.js:

var d = document.getElementById('canvas1');
paper.setup(d);
function onFrame(event) {   //this function does not run 
console.log("test");        
}
var raster = new paper.Raster('/static/notebook/js/turtle.png'); //this works?

but it does not run. I also noticed onkeydown does not work. I believe this has something to do with the PaperScope but I am unsure. I can create rasters, paths and lines, they all display fine, except the functions don't run. I am trying to get it to animate in IPython Notebook.

You could try to call call paper.js with

c.type="text/paperscript";

and see if this helps. Or execute your code with PaperScript.execute(code, scope)
