that.setDate is not a function

The error message "that.setDate is not a function" usually occurs when you try to call the setDate() method on an object that is not a Date.
Make sure that the variable "that" is actually a Date object before calling the setDate() method on it. You can check the type of "that" using the typeof operator. If it is not a Date object, you can create a new Date object and assign it to "that".
Here's an example:
```
let that = new Date();
if (typeof that !== 'object' || that.constructor !== Date) {
that = new Date();
}
that.setDate(15);
```

: date4.locale is not a function
在使用antd组件DatePicker时,出现date.locale is not a function错误,这是因为在使用DatePicker组件时,需要引入locale,并使用local参数。下面是一个示例代码,可以帮助你解决这个问题:
```javascript
import React, { useState } from 'react';
import ReactDOM from 'react-dom';
import 'antd/dist/antd.css';import { DatePicker } from 'antd';
import locale from 'antd/es/date-picker/locale/zh_CN';
function App() {
const [date, setDate] = useState(null);
function handleDateChange(value) {
setDate(value);
}
return (
<div>
<DatePicker locale={locale} value={date} onChange={handleDateChange} />
</div>
);
}
ReactDOM.render(<App />, document.getElementById('root'));
```
在上面的代码中,我们引入了locale,并将其传递给DatePicker组件的local属性。这样就可以解决date.locale is not a function错误了。
