Hi,

I have a asp:TextBox, in which the user inserts a date. Now I like to compare the month of the date with my current month and if it's older then the current month show a text.

JavaScript

function InsertProjectCharging() {
            var date = $('#<%=txtDateFrom%>').val();
            if (ParseInt(date.substring(3, 2)) < (now.getMonth() + 1)) $('.dateValidation').show();
            else {
                ......
            }
        }

Would be really nice, if someone could help me!

What I have tried:

I also tried it with Number(month) instead of parseInt

Work with them as dates

JavaScript

var now = new Date();
var date = $('#<%=txtDateFrom%>').val();
var ddate = new Date(date);

	if(ddate.getMonth() < now.getMonth() + 1)
		alert('true');
	else
		alert('false');

Please note your handling the of edge cases, in other words, you will need logic to also check the year.

Thanks for the down vote. How about adding a useful comment. If you work with them both as dates then the comparison works.
