Javascript为下拉列表的变量添加零

Question

I have this piece of code causing me grief. I need it to change the i variable to 01,02,03.....10,11,12 preferably on this line so as not to disrupt everything which runs off it. I've been messing around trying to do it elsewhere in the function and even the other end, but I keep breaking it. Really if I could just fix it on this line everything else would be fine. Please assist

for (var i=1; i<32; i++)
options[i]=new Option(i, i+0)

//I need the i variable for the rest of the function, it gets changed and outputted later

Answer 1

Is something like this what you're looking for?

 for (var i=1; i<32; i++) i < 10 ? document.write('0' + i + '<br />') : document.write(i + '<br />');

Answer 2

Something like this should work

for (var i=1; i<32; i++) {
    var number = i;
    if (i<10) {
         number = 0 + '' + i;
    }
    console.log(number);
}

You'll get the output into the browsers console, simply change this to wherever you want the text to be.
