Change order in a date with javascript

Question

If I have a date like 8/9/2010 in a textbox, how can I easiest set a variable to the value 201098?

Thanks in advance.

Answer 1

var date = "8/9/2010";

var result = date.split('/').reverse().join('');

To add leading zeros to the month and day (when needed) you could do this:

var date = "8/9/2010";

var result = date.split('/');

for( var i = 2; i--; )
    result[i] = ("0" + result[i]).slice(-2);

result = result.reverse().join('');

Answer 2

I would recommend using Datejs to process your dates.

You can do something like

date.toString("yyyyMMdd");

to get the date in the format you want
