Form with ASP, Javascript and Loops - 8/14/2008 0:54:43
Hello,
I spent way to many hours trying to figure this out... so I wanted to share the solution in hopes of saving others from wasting their time.
Using an ASP loop, we display a table with many rows, each containing a form inside a div. Thus, we have multiple divs on the page, each containing a form.
Furthermore, each div is displayed with a show/hide Javascript function that displays the div when called by clicking a link. Thus, each form is only visible when the appropriate link is clicked. (Code not included here)
Since each div uses this show/hide function they each need a unique div ID so the function knows which div to target.
This is our div containing a form:
<div id="<% =myASPdynamicValue %>">
<form name="myFormName" method="post" action="myProcessingPage.asp">
<input type="text" name="phoneNumber" value="<% =myASPdynamicValue %>
</form>
</div>
Then we use a link instead of a button to submit the form with Javascript.
<a href="javascript:document.myFormName.submit();">Submit</a>
Here is where the glitch came in... the form would not submit! The wild goose chase began with the question does a form work inside a div? Even a hidden div? What about the javascript submit link, does it work when a form is inside a div that has an ID? And on and on. The answers are yes.
Then why does the form submit properly when placed at the top or bottom of my page, but not when placed inside the div?
Finally, the solution is revealed... the form was inside a loop! As I mentioned before, there are multiple divs that each contain a form. Each div was given a unique ID <% =myASPdynamicValue %>. Similarly, each form must be given a unique name as well.
<form name="<% =myASPDynamicValue %>">
The lesson is that each form must have unique name, especially when used inside a loop. Most of you probably already knew this! I wanted to share just in case.
Happy Coding!

Thanks for sharing HW15!
For those of us who did know it, it is always nice for a reminder. And, of course, for those who didn't, this will be a big trouble shooting time saver!
