Javascript E-mails

I am in the process of completeing my javascript e-mail generator. One last part that I need it to include is a from address in the e-mail so that any return e-mails are returned to a certain location. Here is the code I used so far:

<form>
<p align="left" style="word-spacing: 0; line-height: 100%; margin-top: 0; margin-bottom: 0">button
&nbsp;&nbsp;&nbsp;<INPUT TYPE="button" VALUE="Generate E-Mail"
onClick="parent.location='mailto:test@test.com?subject=Test E-mail&from=testhelp@test.com&cc=anothertest@test.com&body=test.%0d%0aTest1 :%0d%0aTest2 :%0d%0aTest3 :%0d%0aTest4 :%0d%0aTest5'">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

</FORM>

I thought that the from portion would work. It makes the from box on the e-mail but then does not populate the value that it is equal to. Can some one help.

You mean like this thing (http://www.webreference.com/js/column70/3.html)?

Yes other than the fact that it does not populate the from on the e-mail like I need. The from is the only part of the script that I can not get to work.

Oh, you can't set the "from" address without a server-side language, which have the capability to set the email headers, which is where the "from" address is stored.

In short, you can't do that with javascript.

Thank you for the help
