Trying to reference a textbox array

Copy linkTweet thisAlerts:
Apr 26.2004

I’m having some trouble with Javascript and Coldfusion.

I have 10 dynamically created textboxes and select boxes on my page. eg:
<cfoutput>
<cfloop from=”1″ to=”10″ index=”Variables.myLoop”>
<input type=”text” name=”textBox#myLoop#”>
….
<select name=”selectbox#myLoop#”>
…

Now I need to do validation on this but I cannot get Javascript to reference the name in a loop

for (foo = 1; foo < 11; foo++) {
if (document.form.textbox[foo].value != “”)
…..

My error occurs in the above line. Can anybody help or point me in the right direction?
Thanks

@violent_jApr 26.2004 — try something like this:

for (foo = 1; foo < 11; foo++) {

name = 'textbox' + foo;

if (document.form.textbox[name].value != "")

@wyattfauthorApr 26.2004 — got it working with

for (foo= 1; foo < 11; foo++) {

var boxname= 'textbox'+ foo;

alert(document.form.elements[boxname].value);

}

Thanks for the help j you got me thinking the right way.
