Javascript将数组中的项目添加到字符串

Question

I am trying to make a multiline string from taking an array of user ids and matching them to the username and then printing the string.

This is what I have so far and am wondering what the proper way to do this would be:

var names;
for(var i in array) {
    var obj = new NSOA.record.oaUser(i);
    var username = obj.name;
    names = names + username;
}

Ideally names would be a string that looks like:

"Smith, Bob, Doe, Jane, Miller, Larry"

Any help you can give would be very much appreciated!

Answer 1

If you're printing to HTML insert a <br> after each array element in the string:

var names = '';
for(var i in array) {
    var obj = new NSOA.record.oaUser(i);
    var username = obj.name;
    names = names + username + '<br>';
}

Answer 2

Push all the name in an array then finally Join it by any separator.

For example:

 var arr = []; arr.push('Smith'); arr.push('Bob'); arr.push('Doe'); arr.push('Jane'); arr.push('Miller'); arr.push('Larry'); document.write(arr.join(', '));
