如何使用 javascript 写入输出?
How can I write output with javascript?
我创建了一个 jsfiddle,其代码旨在用存储在按钮中的字符串替换段落内的字符串。据我所知,这是正确的。但我无法让它工作。有人可以指出我的错误吗?
<p id="arbitraryIdentification">Product information</p>
<button onclick="document.getElementByID('arbitraryIdentification').innerHTML = 'this text just replaced the original text'">text swaperizer</button>
您需要将 id 括在引号中 getElementById
(不是 ID)
看看函数document.getElementById
。
Returns a reference to the element by its ID; the ID is a string which
can be used to identify the element
因此,您的正确代码是:
document.getElementById('unique-key-here')
'getElementByID' 应该是 'getElementById'('Id' 而不是 'ID')
<button onClick="document.getElementById('arbitraryIdentification').innerHTML = 'this text just replaced the original text'">
</button>
