focus on textbox

[KryptoS]

hello I have a problem with focus on a textbox. I have the following code in ASP

<form action=&quot;opslaan.asp&quot; method=&quot;post&quot; name=&quot;formtest&quot;>
<%
While (Not oRS9.EOF)
teller = teller + 1
Response.Write (&quot;<input type=text name=textfield&quot; & teller & &quot; value ='' size = 15 disabled>&quot
%>


now I want to get the focus on lets say: textfield2 (or whatever) I know it's something like:
document.formtest.textfield2.focus()

but this doesn't work, I think it's because I use name=textfield&quot;&teller ... can someone help me?

in the function that is supposed to focus on the textfield :
alert(documen.formtest) - is it undefined ? no ?
-> then
alert(documen.formtest.textfield2) - is it undefined ? no ?
-> then it's NOT because you use textfield&teller
-> yes it's undefined ? then do &quot;view source&quot; on the GENERATED page. What are the name of the fields (ie : what is written here : <input type=text name=...>) ?
-> document.formtest is undefined ? then check the name of the form ...

-> any thing else ? use the netscape console it's done to debug and very very helpful

let me know
but you should have precised WHAT is not working. I mean, as you can't focus a disabled field (as far as i know) maybe everything is fine and working normally

Look this is what my programme is about, I have textfields where I put some data in, after I changed the data in a field I go to a function to test if the data is numeric, if it isn't numeric I want the focus back on that field until it's correct ... now I did some test, and it works when I go to another field whithout using the tab-key. So the problem is when I use the tab-key, my programme looks if the data is correct (if not gives an alert), but then he goes to the next field ... I don't know why ... please help

thank you for you time and help, I call the function after a onChange on the textfield, then a validate the data in the textfield ...

thank you

with tab it doesn't always detect onchange
the very best way to validate any kind of form is :
---
1- set a validation function that will validate ALL of your fields, and, VERY important, let it return true or false. For example :
function check_no_field_is_empty(a_form){
if (a_form.textbox1.value!=&quot;&quot; && a_form.textbox2.value!=&quot;&quot; && a_form.selectbox.selectedIndex!=-1)
return true
else {
alert (&quot;please fill in all the fields&quot
return false
}
}
[&quot;;&quot; at the end of the lines are not important at all, but the return true or false ARE]
----
2- call it ONSUBMIT - onclick or onchange will give various result, often unexpected
<form name=&quot;&quot; action=&quot;&quot; target=&quot;&quot; method=&quot;&quot; onsubmit=&quot;javascript:return check_no_field_is_empty(this)&quot;>
----
this should solve your problem
