Clear a grid or section full of controls on a button press

I have been trying to find a way to have a button clear a grid or section.

What I am hoping to do is have a button in the gird that will remove all values that have been entered. I have a few sections with 40 plus controls that I would need to clear.

Example:

I want to clear 2 radio buttons and a textarea when a button is pressed.

I have tried using the lines below.

<xxforms:variable name="Username-name" select="'******'" as="xstring"/>
<xforms:setvalue ref="instance('fr-form-instance')/*/*[name() = $*****-name]" value=""/>

Or how would I use the line below to uncheck a radio button.

ORBEON.xforms.Document.setValue("foo", Number(fooValue) + 1);

If anyone has any ideas or can point me to a post that is similar that would be great.

Thanks for your time!

Hi Kevin,

This should possible by setting the <xforms:action> for the buttion / trigger,

and it should not be necessary to use the JavaScript hook (and indeed i

think there may be some side effects with that.

<xforms:trigger>

<xforms:label>Clear</xforms:label>

<xforms:action ev:event="DOMActivate">

<xforms:setvalue ref="??????" value="''"/>

</xforms:action>

</xforms:trigger>

I hope that helps. The XForms engine should redraw the controls.

HTH,

Hank

Krowe,

As Erik mentioned in the other thread you could use xxf:iterate.

https://gist.github.com/1837412

Replace the input from the example with a trigger

<xf:input ref="readonly">

<xf:setvalue ev:event="xforms-value-changed" xxf:iterate="../section/*" ref="."/>

</xf:input>
