js随机生成多种颜色

方法一：获取rgba颜色

var colors = []
for (var i = 0; i < 3; i++) {
  var color = "rgba(";
  for (var j = 0; j < 3; j++) {
	color += Math.floor(Math.random() * 256) + ",";
  }
  color += Math.random().toFixed(1) + ")";
  colors.push(color);
}
console.log('输出结果：',colors)

方法二：获取十六进制颜色

var colors = [];
for (var i = 0; i < 3; i++) {
  var color = "#";
  for (var j = 0; j < 6; j++) {
	color += Math.floor(Math.random() * 16).toString(16);
  }
  colors.push(color);
}
console.log('输出结果：',colors)
