Converting String(passed from objc) to Array in Javascript

[ashwinr87]

I am passing a string from objective C to javascript in this way -

NSArray *array = [NSArray arrayWithObjects:@"10",@"9",@"8", nil];
string = [[array valueForKey:@"description"] componentsJoinedByString:@","];

[graphView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"methodName2([%@])", string]];

and in my javascript I am trying to convert the string into an array by -

function methodName2(val)
            {
                var b = val;
                var temp = new Array();
                temp = b.split(',');

                alert(temp);
            }

The way I am using to convert does not seem to work. I am wondering if this is because there is a mismatch in the way the javascript understands the "string" being sent to it?

It would be great if someone could help me out with this.

Well, so exactly what does happen?

Does the JavaScript function get called? Does it throw an exception and bail out? Or does it just not handle the string the way you want?

FWIW, when I call JavaScript from Objective-C, I format calls to functions taking string arguments like this (as opposed to the way you're formatting it... in particular, the square brackets you're using don't seem like they should work).

[NSString stringWithFormat:@"methodName2('%@');", string]

thanks for the reply..
Apparently, "val" in my javascript accepts the string and stores it as an array... so I did not need to do any formatting....
