Ext.Date.add and Datepicker

[bortron5000]

Hello all,

I'm having some problems using the datepicker in conjuction with the Ext.Date.add function. I presently have a datepicker field for an original date, a field that accepts an interval (1 year, 4 months etc), and another datepicker field that should be populated with a new date, equal to the first date plus the interval.

There are no errors, but the value that's appearing in the final date field is doing very bizarre things. If the interval is a month amount it seems to work. However, if I try to add a year amount, it will append the amount to the end of the year (1/1/2012 becomes 1/1/20121), and if I add an amount of days, everything seems to change unpredictably.

The code in my controller is as follows

  calcNext: function(){
    var form = Ext.getCmp('screentypeform'),
        last = form.down('#last').getValue(),
        interval = form.down('#interval').getValue(),
        next = form.down('#next');
    
    if(!last || !interval){
        return;
    }
    
    var intArray = interval.split(" "),
        amt = intArray[0],  //Numeric value
        step = intArray[1].toLowerCase();  //Day, month or year
    
    if(step == "day" || step == "days"){
        next.setValue(Ext.Date.add(last, Ext.Date.DAY, amt));
    }
    else if(step == "month" || step == "months"){
        next.setValue(Ext.Date.add(last, Ext.Date.MONTH, amt));
    }
    else if(step == "year" || step == "years"){
        next.setValue(Ext.Date.add(last, Ext.Date.YEAR, amt));
    }
  }

I have a feeling it has something to do with my initial date formatting, but since I'm getting and setting the values directly from the datepicker fields, I'd have thought that would not be an issue. I've already ensured that the fields have values and that the interval is the correct formatting. Thanks in advance!

In PR3 this is working for me:

var date    = new Date(),
    newDate = Ext.Date.add(date, Ext.Date.YEAR, 1);

console.log(Ext.Date.format(newDate, 'm/d/Y'));

What is the value of last and amt?

Aha, amt is being interpreted as a string, since I split it from a string I guess. If I parse it into an int it works Although I do wonder why it didn't have a problem with months...

Thanks for the assistance.

P.S. there should be a face-palm smiley face.

100% about this I have had many of those moments myself
