This is where my form object was deisgned to be used. It allows you
to dynamically add and remove elements from the form. The code is
attached.
<p>At the moment, it will only work with get forms (data is submitted in
the url).
<p>Eventually, I'll make a way of extending existing widgets to make then
act as form elements.
<p>This is how it works:
<p>DynAPI.include('afrogui.form.form');
<br>DynAPI.onLoad=function() {
<br> testForm=new DynForm("<A HREF="http://www.altavista.yellowpages.com.au/cgi-bin/query">http://www.altavista.yellowpages.com.au/cgi-bin/query</A>");
<br> testForm.addElement(new FormObject('mss','simple'));
<br> testForm.addElement(new FormObject('pg','q'));
<br> testForm.addElement(new FormObject('kl','en'));
<br> testForm.addElement(new FormObject('what','web'));
<br> query = testForm.addElement(new FormObject('q','+jscript
+download +url +contents +source +code'));
<br> alert("A search form is about to be submitted to
Altavista.");
<br> testForm.submit();
<br>};
<p>This sample creates a form used to search altavista. In the FormObject,
the first parameter is the value name and the second is the default value.
<p>To show what could be done, check out <a href="http://www.abchostonline.com/users/mpember/afroapi/examples/demos/dialog_goeureka.html">here</a>.
It also uses a few of my other widgets (dialog, textbox, button, etc).

<p>The DynAPI could really help with something like this. Because
of some
<br>caveats with Netscape, this can be really difficult to do without using
<br>layers. Yes you can add fields to the form, but getting them
to actually
<br>show up without a history.go(0) and then losing all of your previously
<br>entered data is a pain.
<p>What may work better is to create an array to hold your clients values.
<br>Then use a setHTML on a layer to create the form object and display
it to
<br>the user. When the user wants to add a control, add some info
about it to
<br>the array, and make sure you are saving value information to your array
as
<br>well. The recreate the form text and set the HTML to the layer again.
<p>There may be a better way, but this is what jumps to mind.
<p>Hope this helps you get started,
<p>Later,

<br>Subject: [Dynapi-Dev] Create a form which "grows" as user needs
<p>Dear DynApi-Dev
<br>I am trying to use DynAPi in order to create a page which "grows" before
<br>submission.
<br>Namely,
<br>A page is generated which contains some fields to fill in.
<br>However there is one field which may have multiple values.
<br>SInce is not known how many values the user would need to have, and
would
<br>be extremely
<br>poor from a stylistic point of view either hardcode the number of fields
or
<br>use a CGI-posting method
<br>to iterate until the final submit is given, I would like to use DynApi
to
<br>do that.
<p>I have checked dozens of DHTML and Javascript sites as well as dejanews
but
<br>could not figure how
<br>to do that in practical terms.
<p>I have then tried with dynapi and failed.
<p>I would very much appreciate your support / suggestions.
<p>In my opinon, the DynApi does not yet implements ways to handle the
above
<br>problem.
<br>I have tried with the List object but always got the IE5 to crash.
<p>I will very much appreciate your advice.
<br>Sorry for the triviality of the question.
<br>Luca
