Objects and arrays, from JS to Processing.
Feb 5th, 2009, 2:34am  
How can I access objects and arrays from JavaScript space?
Can someone kindly post a working sketch?
Thanks.

Edit: I can access DOM elements but not the properties of JavaScript objects.

Suppose I have

foo = {"one":1,"two":2};

defined globally, when when I try to access "foo" from Processing via the window "JSObject" by using getMember(String <name>), I get a reference to an "Object". And I can't figure out how to get to "one" and "two" from this object.

A quick but semi messy quick fix is to have as many hidden input fields as variables you'll need(could work for arrays but would need string splitting).
Code:

<form>
<input  id="var1" type="hidden" value="my variable here" />
<input  id="var2" type="hidden" value="my other variable here"/>
</form>

Use javascript to change the value of it, from that you should be able to read from that(noting your edit) and work from their. I'll try to find a better solution tomorrow afternoon unless you get a real fix.

Yes, I did think about something like that. Except that my version was a hidden table. And I was too embarassed to mention that in polite company LOL.

Tables would perhaps even map quite well to nested objects as well.

Sadly, no real solutions so far. :(
