Javascript -- confused on the return false -- simple validate function?

[KathyB]

Hi.

I have an hmtl page with a function to see if there are any input text
boxes. If so, that means a user did not complete them (once entered,
my xsl stylesheet makes them text instead of text input boxes, so
there should be NO input boxes when the user is clicking the FINISH
button. However, the FINISH button script still indicates that input
boxes exist...new to this...return false issue? Is there a better way
to do this? I also need to send a querystring or form collection for
(hidden_birth2.aspx?finish=yes). I couldn't get the script right to
open the page with querystring from the function, so I ended up doing
it with this <form> element...probably not the best way. Any help
appreciated! Thanks. Kathy

function CheckInput()
{
var cnAll = document.all;
for (var i=0;i<cnAll.length;i++)
{
if(cnAll(i).tagName=='INPUT')
{
alert("You must first complete and SAVE all user inputs!");
return false; }
}
}

HTML snippet:

<form action="Hidden_Birth2.aspx" method="post" onsubmit="return
CheckInput();">
<input type="Submit" name="finish" value="FINISH">
<b>Click the FINISH button when work instruction is complete.</b>
</form>

I think you need the capital S for it to work ......... but I could be wrong

onSubmit="return validate();"

You are wrong.
In HTML, the case of the letters doesn't matter.
In XHTML, and in Javascript, the on<event> handlers are written in
all lower case.

Are you sure your for loop isn't detecting the "input type submit" ?

Might be worth checking the cnAll(i).type as well.

Also, I think your event handler might need to return true.

Hope that helps,

Ugh, just realized that I should have other input boxes just not
type=TEXT boxes...could someone help me with testing for input elements
where type=TEXT?

Thanks!
