how do convert color code in as3

My Goal is to add the color for text by dynamically.

var tf:TextField = new TextField();
tf.text ="jkg"
tf.textColor = chatData.user;
listChat.addChild(tf);

var number:uint = chatData.user;
tf.textColor = number

Try this

Easy. Just parse the string into a uint.

var txtColor:uint=uint(chatData.user);
tf.textColor=txtColor;

It is very unclear what exactly your problem is/what you are trying to do.

But first, the hex representation of the decimal number 1677721510 is FFFFFF16. Which is white... Not red (which would be FF000016)

A uint is just a unsigned interger. It can be represented bases.

1610 = 208 = 100002 = 1016 = G17

Those are all the same integer, just different ways of showing them, but to most programming languages its the same thing. In flash you represent literal hexidecimal numbers using the 0x notation. In ActionScript's cousin JavaScript, you can create a octal literal by prepending it with a zero (that seriously throws some people off some times 010==8)

But back to what you are asking. I tested it out real quick, and the textColor setter will coalesce a string into uint if you give it a string.

        var tf:TextField = new TextField();
        tf.text = "Test";

        var color;
        color = 0xFF0000; // Red
        color = 16711680; // Red
        color = "16711680"; // Red
        color = "0xFF0000"; // Red

        tf.textColor = color;
        this.addChild(tf);

Those are all acceptable "reds", but really .textColor wants a uint, so the first two are the most valid. But 0xFF0000 == 16711680. They aren't 'different' numbers... They are the same number, just different ways of expressing them.

So, I don't understand what your problem is? Your code should work, and do exactly what you've told it to do...

Check out the global function: parseInt(String[, radix])

It treats strings starting with 0x as hexadecimal ones. If there is no 0x; you can specify 16 for the radix parameter.

tf.textColor = parseInt(chatData.user);
tf.textColor = parseInt(chatData.user, 16);
