    var numberToAddafter = 0;
    var toTime = new date();

Calender is not supported?

you tagged as java, that's why all these misunderstandings, please update the tags in your question first, next time remember to tag the question correctly

That will only increase one day and not on every onclick.

Is this really Java or javascript? It looks like the latter to me.

JavaScript

function addNewDateFrom(){
    var numberToAddafter = 0;  // set number to add as 0
    var toTime = new date();   // get a new time
    toTime.setDate(toTime.getDate() + numberToAddafter++);  // add zero to the time
}

You start each time with a new (zero) value in numberToAddafter, and since this is a local variable, incrementing it to 1 after you add it to the time, serves no purpose, as the variable is immediately deleted.

It javascript, so how should i do? You did just post same code as me ?

Richard MacCutchan 10-Dec-14 9:58am

Yes, and I added comments and explanation as to why it does not work.

Kurac1 10-Dec-14 9:59am

I already know that u posted, but don't now how to do it else.

You need to create your date variable outside of this function and just add 1 to it every time the button is clicked.

Hi,
try this

C#

var toTime = new Date();
Var counter=0
function addNewDateFrom(){
    toTime.setDate(toTime.getDate()+counter);
counter=counter+1;
 }
