随机颜色的二种写法
写法一:
var arr = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "A", "B","C","D"];
?????function Color(){
??????? var str = "#";
??????? for(var i=0;i<6;i++){
????????? str += arr[Math.floor(Math.random()*arr.length)]
??????? }
??????? return str;
?????}
?????
写法二:
????function Color() {
????????? var r = Math.floor(Math.random()*256),
????????????? g = Math.floor(Math.random()*256),
????????????? b = Math.floor(Math.random()*256);
????????? return "rgb("+r+","+g+","+b+")";
?????}
