How can i convert date format at client side

[saint]

Hi Experts 

by using new Date() at client side I'm getting the currrent date

and a UI page date select field is giving me this value

Now I want to compare the selected value with current value to show user a message to change the date to a future date. Server vaidation is present but I need a client popup msg, so they can update the value/ or know why the server did not enter the record as it goes with screen reload.

Please let me know how can I convert 1st value (i.e current date to 2nd date format for validation)

Regards,

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date 

In your brower console run this to see an example

var date = new Date();
date.toDateString();
