Rails spinoffs - Jul 2006 - Abstract insertion question

Hi,

In the following block of Prototype.js when will the catch() block
run? I cannot create conditions in Opera where it will run.

Thanks,
Peter

  if (this.element.insertAdjacentHTML) {
    /* IE and Opera */
    try {
      this.element.insertAdjacentHTML(this.adjacency, this.content);
    } catch (e) {
      // when will this run? can feature detection be used instead?
      var tagName = this.element.tagName.toLowerCase();
      if (tagName === ''tbody'' || tagName ===
''tr'') {
        this.insertContent(this.contentFromAnonymousTable());
      } else {
        throw e;
      }
    }
  }

Well, in the catch it''s looking for a tbody or tr, so I''m
guessing that
trying to insertAdjacentHTML to a tbody or tr fails in IE and Opera.
Maybe it''s only certain versions.

I added the comment about IE and Opera. I don''t know how safari
fit''s
into the picture yet.

Anyone have more info?

Thanks,
