在“onclick"”中更改HTML按钮标题事件

Change HTML button caption in "onclick" event

本文关键字：HTML 按钮 事件 标题 onclick quot      更新时间：2023-09-26

这是我在一个非常简单的页面上的一个按钮的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 Toggle"。显然，我想做更多，但我现在只是调试。然而，我似乎不知道如何做这件简单的事情。

应该像

一样简单
function handleButton(element) 
{
  element.something="Left Garage Toggled";
}

我试过element.value，它似乎不起作用。

好了，下面是没有修饰或空格修复的实际代码....

    </tr>
  </tbody>
</table>
<br>
<script>
function handleButton(caller)
{
caller.innerHTML=caller.id;
}
</script>
</body>
</html>

基本上你需要瞄准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

顺便说一下你的HTML有点乱但我在jsFiddle

中也修正了这个问题

(Thanks to RobG for pointing this out below)

或者你可以使用textContent

function handleButton(element) {
    element.textContent = "Left Garage Toggled";
}

首先你需要正确地关闭你的元素。试试这个. .

<button onclick="handleButton()"
    name="buttonLeft"
    type="button"
    class="myButton"
    id="ButtonLeft">
    Toggle Left Garage
</button>
<br />
Door is Secure
<script>
    function handleButton()
    {
        document.getElementById('ButtonLeft').innerHTML = "Left Garage Toggled";
    }
</script>

如果你想的话。将'script'放入.js文件

对于html我发现了一些错误!第5行应该像这样:

id="buttonleft">Toggle Left Garage</button>

谢谢大家的帮助。原来是comppozer中的预览浏览器出了问题。它似乎根本不执行JS。我在Chrome中打开了底层文件，它工作得很完美(经你们中的一些人修改....)

谢谢你的关注。
