CForms: conditional display of widgets

How can I do to display a certain widget in a form only if a specific
condition is met?

 

Depending on the value of a drop-down menu in the form, another widget
should be displayed or not,

dynamically, not only when the form is first presented.

 

Thanks

Hi Fernando,

 

use the JX-Templates. In Order to make Cforms work you have to ad the
following as child of the templates root:

            <jx:import
uri="resource://org/apache/cocoon/forms/generation/jx-macros.xml"/>

And then stop using the forms generator but to use a normal resource or ile
generator and use the Forms transformer:

            <map:transform type="forms"/>

Then all you can do the following:
            <jx:if
test="${(widget.getChild('curUser_departmentId').getValue() ==
widget.lookupWidget('view/contact/gst').getValue()) &amp;&amp;
(widget.lookupWidget('imported').getValue() == false)}">

                        <ft:widget id="save"/>

            </jx:if>

 

Hope this helps.

Oh just forgot … don’t forget to declre the jx-namespace

xmlns:jx=http://apache.org/cocoon/templates/jx/1.0

It doesn't work in Firefox 1.5.0.1 under Solaris

 

It does work in 1.5.0.3/Windows

 

Thanks

Hi,

 

You could use client-side JavaScript?

 

Add an onkeypress / onclick event on your drop-down menu, which triggers
a JavaScript 'show / hide' function.

 

The JavaScript 'show / hide' function on changing the drop-down value
should set the CSS property for your dynamic widget to be displayed as
{display:none} / {display:block or inline}

 

For Accessibility:

 

By default the CSS display property for the dynamic widget should be set
to display:block / inline.

 

Then use the JavaScript document.write to write out the display on the
rendered html page as {display:none}, for the dynamic widget. That way
if the web user does not have JavaScript available / enabled, your
dynamic field will appear by default.

 

 

Hope this helps,

 

Stuart
