如何在JavaScript/jQuery中格式化日期，如「2014年7月14日」？

Question

我從jQuery BeatPicker獲取日期值，如「2014年7月14日」，我需要將此值設置爲「2014年7月14日」。

有沒有簡單的方法來實現這個使用javascript/jQuery /插件？

感謝

Answer 1

如果你想使用純JavaScript堅持

function formatDate(dateString){ 
    var monthNames = new Array("January", "February", "March", 
     "April", "May", "June", "July", "August", "September", 
     "October", "November", "December"); 

    var dateArray = dateString.split("/"); 
    var month = monthNames[dateArray[1]-1]; 
    var day = dateArray[0]; 
    var year = dateArray[2]; 
    return month + " " + day + ", " + year; 
} 

Answer 2

var text = "14/07/2014"; 
var output = text.replace(/(\d\d)\/(\d\d)\/(\d\d\d\d)/, function($0, $1, $2, $3) { 
    var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; 
    return monthNames[parseInt($2, 10) - 1] + " " + $1 + ", " + $3; 
}); 

完全未經測試，是的 - 正則表達式是雜亂的（應該使用大括號然而，這讀起來更容易），但應該正確地工作...
