canvas element missing

Reported by Florian Jenett | April 23rd, 2010 @ 04:54 AM


i'm trying to set up a simple test system for processing.js sketches. Currently i'm running into this error:

TypeError: Cannot find function getContext in object [object HTMLUnknownElement]

which seems to indicate that the canvas element is not there, right?

    Hi Florian,

    Do a "git pull" -- I just added a canvas stub. All the canvas context functions do nothing, but hopefully your page should not explode.

    Please let me know how this works. I'm sure I missed something.

    heya, that is great!

    i'm getting past the problem mentioned above but am now running into:

    SyntaxError: identifier is a reserved word

    at processing.js > p.init > p.executeSketch > eval()
    [around line 6991]

    my code runs fine in any browser supported by processing.js though. since rhino does not give any line-numbers or other hints i'm sort of clueless. any ideas?

    I would post this to google groups, as my knowledge of what rhino does/how it works is limited.


    good luck!

    ok, just wanted to make sure it's not related to the canvas element you added.
