<p>有没有办法让我在这个函数中写更少的代码行？我希望当你按下其中一个按钮时，它会在两种颜色之间切换。函数green()是red的完全相反。</p> <pre class="lang-html prettyprint-override"><code><h1 id="header">红色还是绿色</h1> <button id="redButton" onclick="red()">红色</button> <button id="greenButton" onclick="green()">绿色</button> </code></pre> <pre class="brush:php;toolbar:false;">function red() { document.getElementById("header").innerHTML = "红色" document.getElementById('header').style.color = "red" document.getElementById('redButton').style.color = "white" document.getElementById('redButton').style.backgroundColor = "red" document.getElementById('greenButton').style.color = "black" document.getElementById('greenButton').style.backgroundColor = "grey" }</pre></p>
