I would like to do the following :
Hide a div <div id="one"> if a string (textstring) or if another div (<div id="two">) is included in the html code of one page of my web site.
The div to hide is as follows :
I guess that it should be possible to test with innerhtml whether textstring or div id="two" is absent or present.
But unfortunately, I am unable to write the expected code.
So, I thank anyone in advance for any help in this matter.
