Encoding for Return value

I've got this javascript:

<a href="javascript:addtext('q');">q</a>

When it is clicked it writes text on a textarea.

I went through the encoding and found can do things like this:

This will add a " " (Space)

<a href="javascript:addtext('%20');">Space</a>

And this will add an "á"

<a href="javascript:addtext('&aacute;');">á</a>

Now I want to know how to add the return value. (enter)

As far as I know this are URL encodings so maybe you cant tu the enter value becaus开发者_运维百科e it makes no sense, but I'm just guessing?

Any ideas or workarounds appreciated!

use

<a href="#" onClick="addtext('&aacute;');return false">á</a>

and

<a href="#" onClick="addtext('\n');return false">Linefeed</a>

or

<a href="#" onClick="addtext('%0D%0A');return false">CRLF</a>

The reason for not using the javascript: protocol is that some browsers actually unload the page when you do not return false on an onClick. It is possible to do javascript:void(somejavascript()) to achieve the same thing, but that will give a 404 if the user has turned JS off. Not a huge issue in your app which only works if JS is on, but onClick and return false is the canonical way. I would actually put the return false as the last statement in function addText, and do onClick="return addtext(...)" instead.
