Assuming you have a function like below in Javascript

function getTheName(id)
{
//Some stuff
return name;
}

You can call , pass parameters and get back a value from it like below

NSString *ID = @"THE_ID";
NSString *theJSMethod = [NSString stringWithFormat:@"getTheName('%@')", ID ];
NSString *returnedValueFromJSMethod = [yourWebViewInstance stringByEvaluatingJavaScriptFromString:theJSMethod];
