隨便寫的小東西^__^
先來效果圖，每隔一秒隨機改變背景色和字體顏色。
下面是HTML

<div style="margin:30% 20%;">

下面是JS代碼，引用了JQUERY插件
$(document).ready(function(){
changeColor();
});
var mainOperation = function(){
var objBackColor = getRandomColor();
var objFontColor = getRandomColor();
$(".content").css({'color':objFontColor,'background-color':objBackColor});
// $(".content").css('background-color',objBackColor);
}
var changeColor = function(){
var timer = setInterval('mainOperation()',1000);
document.getElementById("btnStop").onclick = function(){
window.clearInterval(timer);
document.getElementById("span").innerHTML ="^__^||";
};
}
var getRandomColor = function(){
var ColorR = Math.floor(Math.random()*255).toString(16);
var ColorG = Math.floor(Math.random()*255).toString(16);
var ColorB = Math.floor(Math.random()*255).toString(16);
ColorR = 1 == ColorR.length ? '0'+ ColorR : ColorR;
ColorG = 1 == ColorG.length ? '0'+ ColorG : ColorG;
ColorB = 1 == ColorB.length ? '0'+ ColorB : ColorB;
return '#'+ColorR+ColorG+ColorB;
}
