更改材质ui的日期选择器中的formatDate [英] Change formatDate in datepicker of material ui

问题描述

i使用具有redux形式的material-ui datepicker组件.我在这里有一个小问题，看起来很棒.当我更改日期时，它在我的输入字段中显示为yyyy-mm-dd.我想更改它以显示为dd-mm-yyyy.日期选择器具有一个名为formatDate的属性，该属性将一个函数作为输入. 所以我写道:

i using material-ui datepicker component with redux form. It looks amazing by i have a little issue here. When i change the date it appears in my input field as yyyy-mm-dd. I want to change it so as to appear as dd-mm-yyyy. The datepicker has a property called formatDate which takes a function as an input. So i wrote:

<Field
      name="dateFrom"
      component={DatePicker}
      hintText="Ημερομηνία από"
      autoOk
      formatDate={() => moment().format(DD-MM-YYYY)}
    />

但是它似乎不起作用.你有什么主意吗?

but it does not seem to work. Do you have any ideas?

推荐答案

按照

As per DOC:

formatDate ====> 函数 ====>调用此函数进行格式化 输入字段中显示的日期，并应返回一个字符串.

formatDate ====> function ====> This function is called to format the date displayed in the input field, and should return a string.

签名:函数(日期:对象)=>任何日期:日期对象为 格式化.返回(任意):格式化日期.

Signature: function(date: object) => any date: Date object to be formatted. returns (any): The formatted date.

---

将选定的日期作为formatDate函数的参数接收，更改日期的格式并将格式化程序的值作为字符串返回.

---

Receive the selected date as an argument of formatDate function, change the format of the date and return the formatter value as a string.

另一个变化是:

format(DD-MM-YYYY)

DD-MM-YYYY应该是这样的字符串:

DD-MM-YYYY should be a string like this:

format('DD-MM-YYYY')

这样写:

<Field
      name="dateFrom"
      component={DatePicker}
      hintText="Ημερομηνία από"
      autoOk
      formatDate={(date) => moment(date).format('DD-MM-YYYY')}
/>
