How to modify such data in JS arrays

Question

Got issue My javascript array contains dates for ex. 19.4.2003,28.11.1997,3.1,,29.6,7.11.2008 (date-month-year). As you can see some of dates are missing ( just ,, ) and some are without a year (for ex. 29.6).
The array above should looks like: 19.4,28.11,3.1,,29.6,7.11 Then I need to find an element and get its index with jQuery.inArray("searchVar", myArr); The code is below

if (data.response) { //response from social network
    var f_cnt = data.response.length;
    for(var i=0;i<f_cnt;i++) { 
        holidaysArr.push(data.response[i].bdate); //pushing date in array
        //modify in loop? or call function to modify later?
    }
    holidaysLoaded=true; // just flag
}

Pushing (ok) -> modifying -> searching for element. Need your help.

UPDATE
While making project understand I need to call social network API more than once so saved data in my array. Check it:

    if (data.response) {
    friends_data = data.response.sort(sFirstName); //sorting nvm
    f_cnt = data.response.length; //count of arrayfields
    holidaysLoaded=true;    //flag
}

So array has uid, first_name, last_name, bdate atm. Not just bdate as hour ago. Question is: How to modify all friends_data[i].bdate with match? Empty birthdays have undefined atm. I think I need something like

for(var i=0;i<f_cnt;i++){
   friends_data[i].bdate = cutFunc(friends_data[i].bdate);
}

and form cutFunc(param) with checking on undefined, if not it will match with your function?

UPDATE 2 cutFunc should be smth like this:

function cutFunc(param) {
if(param==undefined) return
else return param.match(/\d+\.\d+/g);
}

thank you :)

Hi, if you're using my solution you just have to change holidaysArr.push(data.response[i].bdate); to holidaysArr.push(cutFunc(data.response[i].bdate));. Also, I would return ""; from the cutFunc if param==undefined. — Skyrim

This gets a holiday array with just days.month

if (data.response) { //response from social network
    var f_cnt = data.response.length;
    for(var i=0;i<f_cnt;i++) { 
        holidaysArr.push(data.response[i].bdate); //pushing date in array
        //modify in loop? or call function to modify later?
    }
          holidaysArr = (holidasArr.join(',')).match(/\d+\.\d+/g);
    holidaysLoaded=true; // just flag
}

EDIT Sorry the regex was wrong; it's been modified with correct regex

EDIT Here's a JSFiddle Link

np...the jsfiddle link I had didn't initially have sample .year data in it, but the new one does (both links point to the new one, now)
