Rad Editor adds line break to empty content in Firefox

[Albert Shenker]

If you load an editor with some content, and then delete all the content (by using the keyboard delete key), the "Content" property of the edirot contains a rogue "<br />" tag when it should be empty. This is true even if the original content never occuped more than one line.This only seems to occur in Firefox. Is there any way to avoid this <br /> tag?

Hello Albert,

The observed behavior is due to the Rich Text Editing engine of Firefox and it is not caused by code in RadEditor source. The browser automatically ads a <br> tag when the content area is empty.

What you can do is make a check and if the content area contains only a single <br> tag to strip it.

All the best,

Is there a better solution for this problem availble yet?

I would like to check whether mandatory fields are filled in. I can not know whether the user inserted a linebreak or Firefox did it after the user empied the control.

Hi Erik,

I suggest first verifying if the ConvertToXhtml filter is not disabled. This filter provides a logic to strip the unwanted BR tag.

If the filter is enabled, then the only possible way to resolve this browser behavior is by implementing the suggested logic by Rumen.

Note that a BR tag is added when Enter or Shift+Enter is pressed, therefore in every case only a blank new line still is blank content area. So the suggested logic should fir your requirements.
