Mootools 1.2教程 输入过滤第一部分（数字）(2)

var changeColor = function(red_value, green_value, blue_value){
//Try to make sure everything is an integer
red_value = red_value.toInt();
green_value = green_value.toInt();
blue_value = blue_value.toInt();
//Set default values on anything thats Not a Number
if ($type(red_value) != 'number'){red_value = 0;}
if ($type(green_value) != 'number'){green_value = 0;}
if ($type(blue_value) != 'number'){blue_value = 0;}
//Limit Everything to the RGB Scale (0 - 255)
red_value = red_value.limit(0, 255);
green_value = green_value.limit(0, 255);
blue_value = blue_value.limit(0, 255);
//Calculate hex value
var color = [red_value, green_value, blue_value].rgbToHex();
alert('Converts to : ' + color);
}
