这是我在一个非常简单的页面上的按钮的 HTML:
<button onclick="handleButton(this)"
name="buttonLeft"
type="button"
class="myButton"
id="ButtonLeft">Toggle Left Garage</button>
<br />Door is Secure</td>
在我的 onclick 事件处理程序 (handleButton()) 中，我想将标题从“Toggle Left Garage”更改为“Left Garage Toggled”。显然，我想做更多，但我现在只是在调试。然而，我似乎不知道如何做这个简单的事情。
应该很简单
function handleButton(element)
{
element.something="Left Garage Toggled";
}
我尝试了element.value，但它似乎不起作用。
好的，这是没有修饰或间距修复的实际代码......

最佳答案
基本上，您需要定位innerHTML。
jsFiddle:https://jsfiddle.net/grwovnyv/
Javascript
function handleButton(element) {
element.innerHTML = "Left Garage Toggled";
}
HTML
<button onclick="handleButton(this)" name="buttonLeft" type="button" class="myButton" id="ButtonLeft">Toggle Left Garager</button>
<br/>Door is Secure
顺便说一句，你的 HTML 有点奇怪，但我也在 jsFiddle 中修复了这个问题
(感谢 RobG 在下面指出这一点)
或者你可以使用textContent
function handleButton(element) {
element.textContent = "Left Garage Toggled";
}
