Uncaught TypeError: Cannot set properties of null (setting 'status')错误的意思是,无法设置未定义或null引用的属性status。这通常发生在你尝试设置一个不存在的元素的属性时。可能的原因是你的代码中没有找到名为status的元素,或者在尝试设置其属性之前,该元素尚未完全加载。
解决此问题的一种方法是确保你的代码中存在名为status的元素,并且该元素已经完全加载。你可以通过在加载完成之后再执行相关操作,或者将代码放在文档的底部来实现。
另一种可能的原因是你的代码中使用了不正确的元素引用。请确保你的代码中的元素引用是正确的,并正确命名。

Uncaught TypeError: Cannot set properties of null (setting
'innerHTML')
This error message indicates that you are trying to set the innerHTML property of a null value, which is not possible. This usually happens when you are trying to access an element in the DOM that does not exist, or has not been loaded yet.
To fix this error, you should first check that the element you are trying to access exists in the DOM. You can do this by using the document.getElementById() method to retrieve the element by its ID. If the element does not exist, you can create it dynamically using the document.createElement() method.
Additionally, you should make sure that your JavaScript code is executed after the HTML document has been fully loaded. You can do this by placing your script tags at the end of the HTML document, or by using the window.onload event to ensure that your code is executed only after the page has finished loading.
Uncaught TypeError: Cannot set properties of null
这个错误通常发生在你尝试在 null 值上设置属性时。意味着你正在访问一个不存在的对象或元素。请确保你在设置属性之前正确地初始化了对象,并且对象不是 null。
例如,如果你正在尝试通过以下方式设置一个元素的属性:
```javascript
var element = document.getElementById('myElement');
element.style.color = 'red';
```
请确保 `getElementById` 方法返回一个有效的元素,而不是 null。如果元素不存在,你将无法设置它的属性。
你可以通过在设置属性之前添加一些验证来防止此错误的发生,例如:
```javascript
var element = document.getElementById('myElement');
if (element !== null) {
element.style.color = 'red';
}
```
这样,只有当元素存在时才会设置其属性,否则就不会执行任何操作,避免出现 TypeError。
