Passing hexadecimal color values from Xcode to Javascript

[ashwinr87]

Hi,

I am trying to pass a Hexadecimal color value from objectiveC to Javascript. I am displaying a graph and I am trying to pass the color to javascript so that I dont need to hardcode it in my html page.

Here is what I do -

In my .m File,

NSArray *colorArray = [NSArray arrayWithObjects:@"FFFFFF",@"000000", nil];
    
    colorString = [[colorArray valueForKey:@"description"] componentsJoinedByString:@","];

In my webViewDidFinishLoad function,

[graphView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"methodName1([%@])", colorString]];

However, the javascript is not able to accept the values.

In my Javascript function, what should I do to accept the values - FFFFFF and 000000 so that I can use them.

I am trying to use the colors like this -

line1.Set('chart.colors', ['FF0000', '000000']);

where instead of giving the hexadecimal values there, I would like to get it from objC.

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

Is the quoting required ? You are not surrouding the color code with them.

here is what I did to get it working..

NSArray *array1 = [NSArray arrayWithObjects:@"000000",@"8B0000", nil];
colorString = [NSString stringWithFormat:@"'%@'", [array1 componentsJoinedByString:@"','"]];

and in my javascript -

line1.Set('chart.colors', [val1[0], val1[1]]);

by this I got color to my graph...
