问题描述
如何从您想要的格式的字符串格式化日期?
how to format a date from a string in the format you want?
var dateString = "31/05/2014 12:53:51";
// function only accepts dates in the format "yyyy / mm / dd"
var date = new Date (dateString);
推荐答案
解析OP中的字符串的一个简单的函数是:
A simple function to parse the string in the OP is:
// Return a Date object
// Expects string in format d/m/y h:m:s
// Separator is not important, order is
function parseDate(s) {
var b = s.split(/\D+/);
return new Date(b[2], --b[1], b[0], b[3], b[4], b[5]);
}
或者如果您只想重新格式化字符串(我猜你不会数字和分隔符之间的空格):
or if you just want to reformat the string (I guessed that you don't want the spaces between the numbers and separator):
// Return a date in "yyyy / mm / dd" format
// Expects string in format d/m/y h:m:s
// Separator is not important, order is
function reformatDate(s) {
// Helper to format single digit numbers
function z(n) {return (n<10? '0' : '') + +n;}
var b = s.split(/\D+/);
return b[2] + '/' + z(b[1]) + '/' + z(b[0]);
}
帮助函数仅用于单数位数未填充输入。如果您有信心,他们一直是,您可以删除它。
The helper function is used just in case single digit numbers aren't padded in the input. If you're confident that they always are, you can remove it.
