I've got a web application, consisting mainly of a big
form with information. The
form is split into multiple tabs, to make it more readable for the user:
<form>
<div id="tabs">
<ul>
<li><a href="#tab1">Tab1</a></li>
<li><a href="#tab2">Tab2</a></li>
</ul>
<div id="tab1">A big table with a lot of input rows</div>
<div id="tab2">A big table with a lot of input rows</div>
</div>
</form>
The
form is dynamically extended (extra rows are added to the tables).
Every 10 seconds the
form is serialized and synchronized with the server.
I now want to add an interactive
form on one of the tabs: when a user enters a name in a field, this information is sent to the server and an id associated with that name is returned. This id is used as an identifier for some dynamically added
form fields.
A quick sketchup of such a page would look like this:
<form action="bigform.php">
<div id="tabs">
<ul>
<li><a href="#tab1">Tab1</a></li>
<li><a href="#tab2">Tab2</a></li>
</ul>
<div id="tab1">A big table with a lot of input rows</div>
<div id="tab2">
<div class="associatedinfo">
<p>Information for Joe</p>
<ul>
<li><input name="associated[26][]" /></li>
<li><input name="associated[26][]" /></li>
</ul>
</div>
<div class="associatedinfo">
<p>Information for Jill</p>
<ul>
<li><input name="associated[12][]" /></li>
<li><input name="associated[12][]" /></li>
</ul>
</div>
<div id="newperson">
<form action="newform.php">
<p>Add another person:</p>
<input name="extra" /><input type="
submit" value="Add" />
</form>
</div>
</div>
</div>
</form>
The above will not work: nested forms are not allowed in HTML. However, I really need to display the
form on that tab: it's part of the functionality of that page. I also want the behaviour of a separate form: when the user hits return in the
form field, the "Add"
submit button is pressed and a
submit action is triggered on the partial
form.
What is the best way to solve this problem?
