Accessing JavaScript arrays from Flash 2

[BillyRayPreachersSon]

Hi...

I'm looking for a way to read data from a JavaScript array based upon the same page as my movie. I'm using ActionScript 2.0 (and exporting the movie as Flash 6, from Flash 8).

The array contains fairly simple data:

var count_data = [];
count_data[count_data.length] = { date:'20060301', amount:234 };
count_data[count_data.length] = { date:'20060302', amount:444 };
count_data[count_data.length] = { date:'20060303', amount:2335 };
count_data[count_data.length] = { date:'20060304', amount:446 };
count_data[count_data.length] = { date:'20060305', amount:465 };

If it helps, I have Macromedia's Flash / JavaScript Integration Kit (JavaScriptFlashGateway.js) included on the page.

I know I could use an XML file, but for technical reasons, this is not feasible.

The only reason I'm looking to read directly from the array is that there could be a fair amount of data (365 strings and 365 integers), and don't know if there is a limit on the amount of data you can pass in the URL:

myFlashMovie.swf?data1=abc&value1=1&data2=def&value2=7 ... data365=xyz&value365=42

Thanks!

according to macromedia there is no limit on amount of data that can be passed from flash to javascript

from javascript to flash they say its ~40k


dont know if you seen these tuts but they may help

Around 40Kb, eh?... well, I think that's more than enough for my needs, so I'll do it that way.

I was thinking the limit would be about 2.5Kb or something small.

Thanks for the info.

You may be able to pass 40KB data, but not by using the URI query string like you're doing. It is limited to 255 bytes, and browsers do not like more than c. 2000 characters URI.

For that and other reasons you may want to use FlashVars instead.

Excellent - after reading the Macromedia site, it seems that I can safely assume a 64Kb limit for FlashVars - even better!

Thanks for that,
Dan
