what would be the best way to sort an array of date strings as such :
var array = ["Tue 7/28", "Sat 8/1", "Sun 8/2", "Mon 7/27", "Thu 7/30", "Fri 7/31", "Wed 7/29"];
into this:
var array = ["Mon 7/27", "Tue 7/28", "Wed 7/29", "Thu 7/30", "Fri 7/31", "Sat 8/1", "Sun 8/2"];
You need to make the dates comparable somehow, so you can use a function to convert them into something comparable. You can skip the weekday and get the month and day and turn that into a number:
function decodeDate(s) {
parts = s.substr(4).split('/');
return parseInt(parts[0], 10) * 40 + parseInt(parts[1], 10);
}
Using that you can sort the array:
array.sort(function(a, b){ return decodeDate(a) - decodeDate(b); });
Demo:
function decodeDate(s) {
parts = s.substr(4).split('/');
return parseInt(parts[0], 10) * 40 + parseInt(parts[1], 10);
}
var array = ["Tue 7/28", "Sat 8/1", "Sun 8/2", "Mon 7/27", "Thu 7/30", "Fri 7/31", "Wed 7/29"];
array.sort(function(a, b){ return decodeDate(a) - decodeDate(b); });
document.write(JSON.stringify(array));
