let demo = document.getElementById("#demo");
demo.innerText("yo");
<!DOCTYPE html>
<html lang="en">
<head>

<body>
<script src="javascript.js"></script>
<p id="demo"></p>

最佳答案
//currently your id is demo
let demo = document.getElementById("demo");
demo.innerText="yo";
///if your id is #demo use this
let demo2 = document.getElementById("#demo");
demo2.innerText="yolo";

<script src="javascript.js"></script>
<p id="demo"></p>
<p id="#demo"></p>
</body>
</html>
由于您的ID是
demo
,而不是#demo
,因此您需要这样编写代码:let demo = document.getElementById("demo"); // don't use #
demo.innerText = "yo"; // Also change innerText like this
对于更改
innerText
属性,请查看docs。 innerText
不是方法。关于javascript - 未捕获的TypeError:无法读取null的属性'innerText',我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/56441944/
