Howto do onBlur field validation in form with more fields

[431964]

Hi,<br>
<br>
I want my form validation to be on a field by field basis.<br>
Therefore I use the onBlur() event. <br>
<br>
Problem is that depending on the user action. Mouse is move is oke but tab produces a browser lockup between the field that is left and the next one its about to enter.<br>
<br>
<br>
I do like this:<br>
<br>
in: verify.js<br>
<br>
----knip-------<br>
//&lt;SCRIPT LANGUAGE=&quot;JavaScript&quot;&gt;<br>
<br>
function senderCheck() {<br>
<br>
if (document.forms[0].sender.value.length == 0 ) {<br>
ErrorMsg(&quot;Sender name is mandatory!&quot;<br>
document.forms[0].sender.select(); <br>
}<br>
}<br>
//=end=====================================================<br>
<br>
function recipCheck() {<br>
<br>
if ( document.forms[0].recipient.value.length == 0 ) {<br>
ErrorMsg(&quot;No Recipient name is given!&quot;<br>
document.forms[0].recipient.select(); <br>
}<br>
}<br>
<br>
remark: ErrorMsg is just a alert() function.<br>
These functions are nearly identical but must stay apart for other reasons.<br>

&lt;head&gt;<br>
&lt;script type=&quot;text/javascript&quot; language=&quot;JavaScript&quot; src=&quot;verify.js&quot;&gt;&lt;/script&gt; <br>
&lt;/head&gt;<br>
----knip-------<br>
&lt;form name=&quot;theForm&quot; method=&quot;post&quot; action=&quot;../../cgi-bin/some.cgi&quot; target=&quot;content&quot;&gt;<br>
sender:<br>
&lt;input type=&quot;text&quot; size=&quot;35&quot; name=&quot;sender&quot; onBlur=&quot;senderCheck()&quot;&gt; *<br>
recipient:<br>
&lt;input type=&quot;text&quot; size=&quot;35&quot; maxlength=&quot;25&quot; name=&quot;recipient&quot; onBlur=&quot;recipCheck()&quot;&gt; *<br>
&lt;input type=&quot;submit&quot; value=&quot;Send&quot;&gt;<br>
&lt;input type=&quot;reset&quot; value=&quot;Cancel&quot;&gt;<br>
&lt;/form&gt;<br>
<br>
----knip-------<br>
<br>
<br>
and besides, is there anybody out here who has some advise <br>
or pointers on to some handy tools for writing and DEBUGGING JavaScript code ? <br>
Netscapes debugger didnt work (js error prevented downloading, anyway didnt found the app)<br>
<br>
Ohja it must work offline aswell<br>
<br>
<br>
Thank you all very much<br>

try
..... onChange=&quot;whateverCheck()&quot;>....
If the user moves from the field at all it will run the function. X-)
