如何在以下JavaScript循环中消除逗号？

Question

The code:

var fileChapters = (function() {
  var results = [];
  for (i = 0, len = posts.length; i < len; _i++) {
    var post = posts[i];
    results.push("<p><a href=\"#chap1\">" + post.title + "</a></p>\n\n");
  }
  return results;
});

console log to fileChapters :

["<p><a href="#chap1">Post 1</a></p>↵↵", "<p><a href="#chap1">Post 2</a></p>↵↵", "<p><a href="#chap1">Untitled</a></p>↵↵", "<p><a href="#chap1">Untitled</a></p>↵↵", "<p><a href="#chap1">Untitled</a></p>↵↵"]

Now when I do push:

file.unshift fileTOC

I end up with the following HTML:

  <p><a href="#chap1">Post 1</a></p>

,<p><a href="#chap1">Post 2</a></p>

,<p><a href="#chap1">Untitled</a></p>

,<p><a href="#chap1">Untitled</a></p>

,<p><a href="#chap1">Untitled</a></p>

What's happening here? And how to solve it?

Answer 1

It is an array, it has commas when you do toString()

If you do not want the commas, use

return results.join("");
