hello, everyone.
I am trying to replace"留言" with "comments"
I've tried http://www.w3schools.com/jsref/jsref_replace.asp
but it didn't work. anyone can help out? thanks.

A:

You can try to use this:
[].forEach.call(document.getElementsByClassName('author'), function(comment) {
    comment.innerHTML = comment.innerHTML.replace('留言', 'comments');
});
