Remove bold tags on highlight

[skippt]

Hi,

I'm working on trying to make a string in a textarea bold by inserting bold tags.

The script I have can be found below:

The script will insert bold tags but I'm trying to work out a way in which I can remove the bold tags when highlighting.

It would have to check whether bold tags are wrapped around the string and then remove them. I'd imagine it would work something like this:


If only part of the bold string is highlighted, insert a </b> tag at the beginning and insert of </b> tag at the end of the string.


If left side of the bold string is highlighted, remove <b> tag from beginning and move it to the end of the highlighted string.
If right side of the bold string is highlighted, remove </b> tag from end and move it to the beginning of highlighted string.

Can anyone teach me how I would do this please?

So you want to remove any bold tags that are within the highlighted string?
