Material-Ui DatePicker更改爲字符串

Question

有沒有辦法使Material-UI DatePicker的值爲String而不是Date Object？我只想要YYYY-MM-DD作爲日期值。現在我正在做的是在將它發送到服務器之前進行編輯。

Answer 1

Date Javascript中的對象具有將日期更改爲字符串的原型函數。

var date = new Date(); 
var abc = date.toString(); 

console.log(abc); // Returns "Thu Feb 16 2017 12:01:19 GMT-0800 (PST)" 

如果你指的是如何將日期更改爲特定格式發送給服務器之前，你可以使用moment.js 是使用像 moment(dateObject, 'YYYY-MM-DD')一個功能，您從DatePicker提取dateObject後。

這裏是一個快速小提琴，顯示時刻在行動格式： http://jsfiddle.net/fjz56wgg/

這是最好的材料UI日期選擇器，我發現至今。它允許用戶輸入和選擇一個日期，並顯示一個字符串值（也可以用作輸入值）。希望能幫助到你！
