Convert number into date using javascript
提问by Carlos
I have date in without "/" in text field and it is in mm/dd/yyformat. We received input in this format 03292014. I want to get month,date and year from this number like 03/29/2014
我在文本字段中有没有“/”的日期，它是mm/dd/yy格式。我们收到了这种格式的输入 03292014。我想从这个数字中获取月份、日期和年份，例如 03/29/2014
var m = new Date(3292014*1000)
console.log(m.toGMTString())

You could do this :
你可以这样做：
var m = '03292014'.match(/(\d\d)(\d\d)(\d\d\d\d)/);
var d = new Date(m[3], m[1] - 1, m[2]);
Or convert the input into a standard "YYYY-MM-DD" format :
或者将输入转换为标准的“YYYY-MM-DD”格式：
var d = new Date('03292014'.replace(
/(\d\d)(\d\d)(\d\d\d\d)/, '--'
));

According to Xotic750's comment, in case you just want to change the format :
根据Xotic750 的评论，如果您只想更改格式：
var input = '03292014';
input = input.replace(
/(\d\d)(\d\d)\d\d(\d\d)/, '//'
);
input; // "03/29/14"

Get the components from the input, then you can create a Dateobject from them. Example:
从输入中获取组件，然后您可以Date从它们创建一个对象。例子：
var input = '03292014';
var year = parseInt(input.substr(4), 10);
var day = parseInt(input.substr(2, 2), 10);
var month = parseInt(input.substr(0, 2), 10);
var date = new Date(year, month - 1, day);
