一个随机颜色的函数
function randomColor() {//16进制方式表示颜色0-Fvar arrHex = ["0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F"];var strHex = "#";var index;for(var i = 0; i < 6; i++) {//取得0-15之间的随机整数index = Math.round(Math.random() * 15);strHex += arrHex[index];}return strHex;}function changeColor(){var links = $('#tip_bgColor span');for(var i=0;i<links.length;i++){var bgColor = randomColor();//改变背景色的代码,links[i].style.backgroundColor = bgColor;}}changeColor();$('.next_eff').click(function(){changeColor();})
