HTML Display Current date

Here's one way. You have to get the individual components from the date object (day, month & year) and then build and format the string however you wish.

n =  new Date();
y = n.getFullYear();
m = n.getMonth() + 1;
d = n.getDate();
document.getElementById("date").innerHTML = m + "/" + d + "/" + y;

<p id="date"></p>

Use Date::toLocaleDateString.

new Date().toLocaleDateString()
= "9/13/2015"

You don't need to set innerHTML, just by writing

<p>
<script> document.write(new Date().toLocaleDateString()); </script>
</p>

will work.

P.S.

new Date().toDateString()
= "Sun Sep 13 2015"

I prefer to use

<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>

that works well
