当单击button2(名为“蓝色”)时，我试图将框的颜色更改为蓝色。
这是不起作用的代码......有人可以帮忙吗？
演示
document.getElementById("button1").addEventListener("click", function(){
document.getElementById("box").style.height = "300px";
document.getElementById("box").style.width = "300px";
});
document.getElementById("button2").addEventListener("click", function(){
document.getElementById("box").style.color = 'blue';
});<!DOCTYPE html>

<p>Press the buttons to change the box!</p>
<div id="box" style="height:150px; width:150px; background-color:orange; margin:25px"></div>
<button id="button1">Grow</button>
<button id="button2">Blue</button>
<button id="button3">Fade</button>
<button id="button4">Reset</button>
<script type="text/javascript" src="Javascript.js"></script>

更改 HTML 元素的背景颜色而不是颜色属性。
document.getElementById("button2").addEventListener("click", function(){
document.getElementById("box").style.backgroundColor = "blue";
});
请在下面找到工作片段:
document.getElementById("button2").addEventListener("click", function(){
document.getElementById("box").style.backgroundColor = "blue";
