JS怎么改变背景颜色

1、首先我们来创建一个p元素,在里面写上hello:。

2、在浏览器界面上的显示如下。

3、接下来我们就为这个p元素来设置背景颜色。

4、接下来看看浏览器中变化。

5、说明我们就已经为p元素改好了背景色,如果要改变颜色的话直接在后面改就好。

JS点击更换网页背景颜色。

javascript脚本:

script type="text/javascript"

// 定义可换的颜色

var colors = ["#ff0000", "#00ff00", "#0000ff", "#ffff00", "#00ffff", "#ff00ff"];

var index = 0;

// 换色方法

function changeColor() {

// 获取颜色代码

var color = colors[index++];

// 更改文档的背景色

document.bgColor = color;

if (index == colors.length) {

index = 0;

}

}

/script

HTML代码:

input type="button" value="换色" onclick="changeColor();" /

怎样用js设置div的背景色

1、首先打dreamware软件,然后在 body中写入一个 div,把div赋予一个 id方便提取;

2、用css写div属性和初始的背景色,width宽度值;height高度值;background初始的背景色。

3、写进script标签,定义一个变量mydiv获取前面定义好的div。

4、然后用onmouseover事件,鼠标移动时触发事件,来控制鼠标在div时,背景色变为红色。

5、接着用onmouseout事件,鼠标离开元素时触发事件,来控制div背景色变为绿色,如图所示。
