<p>is there any downside to add content text through javascript other than it will not shown when if javascrit is disabled?</p>

<p>for example like this <a href="http://stackoverflow.com/questions/1899913/how-to-detect-linked-pdf-on-a-page-and-show-message-to-download-adobe-reader-usin/1899938#1899938">http://stackoverflow.com/questions/1899913/how-to-detect-linked-pdf-on-a-page-and-show-message-to-download-adobe-reader-usin/1899938#1899938</a></p>

<p>if text will not shown to javascript disabled use, no problem and i don't need this text for search engine. </p>

<p>Will it affect to page performance to end user?</p>
