Links do not get deleted correctly

[Damian]

To reproduce:

1. Open sample
   
2. Add a word
   
3. Select the word and create a link from it using the link dialog
   
4. Goto source to see the link is created and return to RT mode
   
5. Select the new link and delete it.
   
6. Goto source again, see that that label of the link is gone but the <a> is still there.
   

Expected result: After deleting the link the <a> should also be deleted.

Can you provide details about how the link is deleted in step 5?

[Damian]

The link is deleted by selecting the link text and pressing the delete key.

I've repeated this on the nightly build. Attaching a screen shot to illustrate.

[Garry Yao]

The link deletion logic with keystroke is browser implicit, you need to

1. IE:
   • Press N+1 Backspace at the end of link text;
   • Press N Del at beginning of link text;
2. FF:
   • Press N+1 Backspace at the end of link text;
   • Press N+1 Del at the beginning of link text;
3. Safari: Press exactly N times with both Backspace and Del

Where N represent the text count of your link.
Sorry, we're not likely to fix the problem at this moment, hopefully above info is helpful to you.

I also find this one quite strange.

The fact is that, during the editor usage, we could have some empty <a> being left in the DOM, due to the implicit browser behavior to some operations. This link deletion is a case. In V2, we simply cleanup empty <a> (with no "name" attribute), but it looks like this is not happening with V3. We could simply implement the same cleanup rule here.

Note that the attached screenshot precisely shows that there is also a <br> inside the link, and in that case it's correct to not have the link deleted because the <br> has not been selected before deletion.

In any case, I'm able to confirm this one, with IE only though, even without the <br>:

1. Load the following HTML:

<p><a href="http://example.com">Test</a></p>

2. Double click on "Test" to select it.

3. Hit DEL to delete it.

4. Switch back to source. You will have the following, which is wrong:

<p>
	<a href="http://example.com"></a></p>

Please open a ticket for it (for the 3.1).

[Garry Yao]

Fixed with [3782].
The new ticket is opened as #3841 for the mentioned problem.

I'm not sure what part of this defect is fixed and what remains to be fixed still? I can reproduce this issue as described in the original problem description.

[Garry Yao]

The subject of this fix is removing the empty <a> element unless it represent an anchor.
WFM, could you provide more details?
