javascript使用按钮更改页面背景颜色

Question

I am trying to figure out how to do code for changing the background color of a page with a button 我正在尝试找出如何使用按钮更改页面背景色的代码

so basically I have the code for a button written out and its function but im having trouble figuring out what code to use to make the button change the color of the entire page 所以基本上我已经写出了按钮的代码及其功能，但是我在弄清楚使用什么代码使按钮改变整个页面的颜色时遇到了麻烦

<script>
    function changeColor()
    {

    };
    function changeText()
    {
        alert ("change text in this part");
    };
    function sendMsg()
    {
        alert ("change msg content here");
    }
</script>

<body>
    <h1>Welcome to my program!</h1>
        <button onclick="changeColor()">Color</button>
        <button onclick="changeText()">Text</button> </br>
            <p>Can I ask you something Ive always wanted to ask the real Batman?</p> </br>
                 <input type="text" name="">
</body>
