我有這個簡單的jquery函數來自動填充id爲#date_accepted的日期字段。不知道如何格式化輸出。使用jquery函數的格式日期
但我得到這個：Wed Oct 28 2015 10:34:25 GMT-0700 (Pacific Standard Time)這是我不想要的。
我想這一點：2015-10-28.
下面是函數：
<script>
$(function() {
var today = new Date();
$('#date_accepted').val(today)
});
</script>
任何幫助將不勝感激。謝謝。

Date Formated: <div></div>嘗試使用此方法解析出日期：月是從零開始的JavaScript的
$(function() {
var today = new Date();
var date = today.getDate();
var month = today.getMonth() + 1;
var year = today.getFullYear();
var formatted = year + "-" + month + "-" + date;
$('#date_accepted').val(formatted);
});
，所以你必須添加1獲取當前月份。 getYear()以2-3位數格式返回年份。要獲得全年你必須撥打getFullYear()。
jQuery沒有內置任何日期/時間格式。可以告訴，因爲沒有[API文檔中列出]（http://api.jquery.com）。 –
像這樣的話題很容易研究，並且在問問題之前你需要花點功夫 – charlietfl
