I'm messing around object key value stuffs and hit a wall:

If I define an object's key:value pairs in the script and then get the value of a certain key, it works fine.

If I $.get  an external txt file then it returns "undefined" for the value. If I iterate through the same imported file using $.each, it'll faithfully list each key:value pair.

$(document).ready(function() {    
    
// DATE    
    var now = new Date(Date.now());
    var mond = function() {
        return ('0' + (now.getMonth() + 1)).slice(-2);
    }
    var dayd = function() {
        return ('0' + now.getDate()).slice(-2);
    }
    var dayKey = mond() + dayd();
    $.get('alldatestest.txt', function(data) {
        var picsObj = {data};
        alert(picsObj.dayKey);
        /*$.each(picsObj, function(key,value) {
            //alert(key + ':' + value);
            if ( key = dayKey ) {
                //alert('yes');
                alert(value);
            }
        });*/
    });
});    

Here's the external file as reference above:

0810: '',
0811: '100315/5065359-R1-19-20_scaled.jpg',
1004: '100315/5065359-R1-19-20_scaled.jpg',
1008: 'images/CNV00016-interim.jpg'

var picsObj = JSON.parse('{'+data+'}');

Thanks, I'll try it in the am.

Did it work?

Seems to be working now. I had to stick the brackets in the external file & also change its single quotes to double, and switch .dayKey to [dayKey] in the script:

    $.get('alldatestest.txt', function(data) {
        var picsObj = JSON.parse(data);
        alert(dayKey + ' ' + picsObj[dayKey]);
    });

- returns "0812 100315/5065359-R1-19-20_scaled.jpg"

Thanks Peter!

Edit: to clarify, here's the new "alldatestest.txt" -- I also had to wrap keys in quotes per above online parser:
 

{"0810":"images/CNV00016-interim.jpg",
"0812": "100315/5065359-R1-19-20_scaled.jpg",
"1004": "100315/5065359-R1-19-20_scaled.jpg",
"1008": "images/CNV00016-interim.jpg"}

And now you can browse back and forth through the Daily Bad Pictures*, thanks to stack overflow and their diabolical spell
 

Object.keys(obj).indexOf(key)

(you're not supposed to be able to do indexy stuffs on objects, but there you have it  (angel) )
