format a JavaScript date using substring
<p>The below method sends date to text box in this format <code>Wed Sep 14 2016 00:00:00 GMT+0400</code>.
So i tried to use substring method to get date in this format  <code>Sep 14 2016</code></p>

<p>i have tried to it in below code but it didn't work</p>

<p>it return this error <code>Uncaught TypeError: date.substring is not a function</code> </p>

<pre><code>&lt;script&gt;
    $(document).ready(function () {
        var dateval = $('#&lt;%= txtdate.ClientID %&gt;').val();
        if (dateval != '') {

            var options = {
                selectedDate: dateval,
                size: 'medium',
                width: 960
            }
        } else {
            var options = {
                size: 'medium',
                width: 960
            }
        }
        $('#paginator').datepaginator(options);
        $('#paginator').on('selectedDateChanged', function (event, date) {
            $('#&lt;%= txtdate.ClientID %&gt;').val(date.substring(4, 12));
        });
    });
&lt;/script&gt;
