passing values from ios to javaScript

Question

iam working on iOS project and there is a statistics page is already done with JS and when loading it into UIWebView everything works fine with a nice Animation

[WebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]];

and the JS code is executed in document.Ready when the DOM is ready..

 $(document).ready(function () { 
var s1 = [[2002, 112000], [2003, 122000], [2004, 104000], [2005, 99000] ];
});

My problem is the data is generated in IOS and i want to pass this data to the JS to draw the chart with a nice animation,,i didn't find a way to pass a parameter to document.Ready so i make this a function and in IOS call this function and pass the parameters... so i changed my code to ..

-(void)webViewDidFinishLoad:(UIWebView *)webView
{ 
 NSString * param  = @"foo";
 NSString * jsCallBack = [NSString stringWithFormat:@"myFunc('%@')",param];
 [webViewstringByEvaluatingJavaScriptFromString:jsCallBack];
 [webView stringByEvaluatingJavaScriptFromString:jsCallBack];
}

and the JS to

function myFunc (var x) { 
var s1 = [[2002, 112000], [2003, 122000], [2004, 104000], [2005, 99000] ];
};

doing that actually passing parameters BUT the animation doesn't appear anymore for reason i don't know and i have tried this with lots of online ready jS charts when i change the function from document.Ready to another function gets called by IOS they appear but don't animate ....So is there is anyWay to pass a parameters to document.Ready ??

It's not easiest to send your data generated in iOS directly at the beginning? I mean, when you load your UIWebView, you can sent in parameters (POST or GET) your values.
