创建小时数数组：00：00、01：00、02：00

Question

I have the following code:

var hours = [];
for (var i = 0; i < 24; i++) {
   hours.push(i);
}

This creates an array with 0,1,2,3,4..... numbers, but I need: 00:00, 01:00, 02:00.....

Answer 1

this should work:

var hours = [];
for(var i=0; i < 24; i++) {
    hours.push((i < 10 ? "0" : "") + i + ":00");
}

EDIT

If you want to parse these strings back to the respective number (ignoring the minutes) use something like this:

var hourString = "11:00";
var hourAsNumber = parseInt(hourString.split(":")[0], 10);

Answer 2

Use text instead.

var hours = [];
var text_hour;
for (var i = 0; i < 24; i++) {
   if (i > 9) {
      text_hour = i+':00';
   } else {
      text_hour = '0'+i+':00';
   }
   hours.push(text_hour);
}
