Javascript在每个输出的数组值的末尾附加换行符

Question

When I run the following code the br is appended to the end of the the dates list. I am trying to get the br to append after every date value in the array. I tried using a for loop but that doesn't seem to work. What am I doing wrong?

dates = ['2012-09-06 22:39:29', '2012-09-06 22:41:02', '2012-11-05 15:01:10', '2012-11-06 15:37:58', '2012-09-08 10:22:00'];

$('#hi').append(dates.sort() + '<br>');

For loop:

for(i = 0; i < dates.length; i++) {
    $('#hi').append(dates.sort() + '<br>');
}

Answer 1

Try:

dates.sort();
$("#hi").append(dates.join("<br />") + "<br />");

I don't know what you think dates.sort() does, but you're using it weird.

Answer 2

That's because your'e effectively concatenating the whole array with the BR tag. consider the following exapmle:

  dates.sort();
    for(i = 0; i < dates.length; i++) {
        $('#mydiv').append(dates[i] + '<br>');
    }
