JavaScript forms on Mac and PC

Posting to a page with Javascript forms

[TriadJustin]

Im having a problem with a form using javascript. This form is on a page that allows the end user to click a button ontop of a text box and insert the desired html code around the text highlighted. For instance: <b>adf</b> if you hit the bold button on top. This code works fine on a PC but does not work on a Mac. If you hit the button on a mac nothing happens. Does anyone have any suggestions?

Welcome to Webmaster World!

There are some Java applets that do a much better job at this. It will be really hard for you to make it work (using JavaScript) across several browsers/platforms.

Unfortunately I dont have much of a choice. Im an intern and they request that it be done within Javascript. If I gave you the code for the .js do you think that would help?

[DrDoc]

Do they require cross browser compatibility?

[TriadJustin]

NO, both can be IE but one for a Mac and the other for a PC.
