格式化打字稿日期與月份寫的全

Question

我在打字稿這樣的功能

setQuitDetails() { 
    var currentDate = new Date().toLocaleDateString(); 
    this.TodaysDate = currentDate; 
} 

它返回這樣9/12/2017

我想回到這樣September 12, 2017

日止

如何在打字稿文件中實現此目的？

Answer 1

如果正在運行試試這個：

var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; 

var setQuitDetails = function() { 
    var currentDate = new Date(); 
    this.TodaysDate = currentDate; 
    var year = this.TodaysDate.getFullYear(); 
    var month = months[this.TodaysDate.getMonth()]; 
    var day = this.TodaysDate.getDay(); 
    var output = month + ' ' + day + ', ' + year; 

    alert(output); 
    return output; 
} 

setQuitDetails(); 

Answer 2

你可以通過toLocaleString做到這一點：

const options = { 
    month: 'long', 
    day: 'numeric', 
    year: 'numeric' 
} 
console.log(new Date().toLocaleString("en-US", options))); 

==>September 12, 2017
