Is there a way to prevent users signing up using yahoo or hotmail email addresses?

Here is part of my reg. code

[code]
<TD vAlign=top align=left width=”29%” height=26><B>E-Mail Address:</B><BR>&nbsp;</TD>
<TD vAlign=top align=left width=”71%” height=26><input type=”text” size=34 name=frmEmail>
[/code]

@balloonbuffoonFeb 23.2005 — This is Javascript, not PHP:
<i>
</i>&lt;SCRIPT LANGUAGE="JavaScript"&gt;
&lt;!-- Begin
function stripEmail(Email){
var atsign = Email.substring(0,Email.lastIndexOf('@')+1);

var domain = Email.substring(atsign.length,Email.length+1);

if (domain == "yahoo.com") {
alert('Please use an email address that is not from Yahoo!')
}
else if (domain == "hotmail.com") {
alert('Please use an email address that is not from Hotmail!')
}
}


// End --&gt;
&lt;/SCRIPT&gt;
&lt;form&gt;
E-Mail Address:&lt;br&gt;
&lt;input type="text" size=34 name=frmEmail&gt;&lt;br&gt;
&lt;input type=button value="Validate" onClick="stripEmail(frmEmail.value)"&gt;
&lt;/form&gt;

In your form you would just move the onClick="stripEmail(frmEmail.value)" to the submit button.
