Question

I have a table to which i dynamically add rows. The number of days is equal to the date difference of the dates inserted by user. On the dynamic rows i want to add three fields. The first two are date and day filed. For that I need to know the next date and the corresponding day. For example user enters 10-2-2012. I need to insert The next dates like 17-2-2012,18-2-2012… and corresponding days like Wednesday, Thursday..etc
I have used the following function to get next date

function getTomorrow(d,offset)
{
    if (!offset)
    {
       offset = 1
    }
    return new Date(new Date().setDate(d.getDate() + offset));
}

But it shows error 16-2-2012 has no getDate() function. Am not able to find next date and the corresponding day. Is there any way to get it?

You have to convert the string d into a Date object:

function getTomorrow(d,offset){
    if (!offset){
        offset = 1;
    }
    if(typeof(d) === "string"){
        var t = d.split("-"); /* splits dd-mm-year */
        d = new Date(t[2],t[1] - 1, t[0]);
    //  d = new Date(t[2],t[1] - 1, t[0] + 2000); /* for dd-mm-yy */
    }
    return new Date(d.setDate(d.getDate() + offset));
}    

document.write(getTomorrow('16-02-2012',20) + ' test');

var k = getTomorrow('16-02-2012',1);
var myTime = k.getDate()+'-'+(k.getMonth()+1)+'-'+k.getFullYear();

alert(myTime);
