try using filter

function getMonth(a)
{
    var j = array.filter(function(i)
            {
               if(i.amount === a)
               {
                  return i.month;
               }
            });

    return j[0].month; // here we get first matched result
}

var res = getMonth(12185);

res will contain JANUARY here.

Try this, Dynamic code

 <div><input type="button" value="12185" class="className"/>
 <input type="button" value="147421"  class="className"/>
 </div>

for (var i in my_object) {
    var cur = my_object[i];
    $('input[value=' + cur.amount + ']').each(function() {
        var msg = 'Sales Month: ' + cur.month + ' Number: ' + cur.year;

        $(this).parent('div').append('<div>' + msg + '</div>');
    });
}

You can filter data using .filter

var result = array.filter(function(item) {
    return item.amount == 12185;
});

Here is the working Fiddle

var result;
var your_value=12185;
for(var i=0;i<array.length;i++)
{
    if (your_value == array[i].amount)
    {
        result=array[i].month;
        break;
    }
}
alert(result);

You could use a function like this; though the array would have to be global. Here's a JSFiddle.

function getMonth(amount){

    month = "";

    for(i = 0;i<array.length.i++){
        if(array[i].amount === amount){
            month = array[i].month;
            break;
        }
    }

    return month;
}
