I need a very simple email validation script (so simple I can't do it :-( ). can u help?<br />
I have this input field:<br />
<br />
&lt;input name=&quot;register_email&quot; type=&quot;text&quot; size=&quot;30&quot; maxlength=&quot;50&quot; onblur=&quot;this.value=this.va<wbr />lue.replac<wbr />e(/ /g,'_')&quot; onfocus=&quot;change2Msg(2);&quot; value=&quot;&lt;cfif isdefined('url.em')&gt;&lt;cfout<wbr />put&gt;#url.e<wbr />m#&lt;/cfoutp<wbr />ut&gt;&lt;/cfif&gt;<wbr />&quot;&gt;<br />
<br />
I need to FORCE the user to stay in the input field if no '@' or '.' is part of the entered string. &nbsp;I'm sure this is goofy but it would help me with a very simple task I need.<br />
<br />
Does this make sense?<br />
<br />
In otherwords ... when I tab (or click) into this text field 'register_email' and I fail to enter a text string that contains an '@' and an '.' (i.e. fred instead of 'fred@fred.com') then when I leave the field ... force the user BACK into the text input field.<br />
<br />
(i need to keep that onfocus=&quot;change2Msg(2);&quot; code in my line and the coldfusion output field for value.)<br />
<br />
<br />
Thanks for any help!<br />
