昨天在做js 从10种颜色中随机取色，并每次取出的颜色不同的时候，考虑了很多，最终用如下来实现：复制代码代码如下:var colorList = ["#FFFF99","#B5FF91","#94DBFF","#FFBAFF","#FFBD9D","#C7A3ED","#CC9898","#8AC007","#CCC007","#FFAD5C"];for(var i=0;i var bgColor = getColorByRandom(colorList);}function getColorByRandom(colorList){var colorIndex = Math.floor(Math.random()*colorList.length);var color = colorList[colorIndex];colorList.splice(colorIndex,1);return color;}这样便能每次取出的颜色是随机的且都不一样
