Re: [Xsltforms-support] Can you use dispatch to invoke a trigger?

[William V. <wve...@vi...>]

Hi Mark,

What you need is a custom event handler.

First In you xf:model, declare an xf:action that handle a custom event (you assign the name), let's say "next-page", and include on it the actions on the trigger you want to call:

<xf:action ev:event="next-page">
                        <!- lots of stuff here ->
</xf:trigger>

Second, call this event with the action xf:dispatch from the original trigger

<xf:trigger id="next_parent">
            <xf:label>Next Page</xf:label>
            <xf:action ev:event="DOMActivate">
                        <xf:dispatch name="next-page" id="model1" />
            </xf:action>
</xf:trigger>

In this example, next-page is the name of the custom event and model1 is the id attribute of the xf:model that contains the event handler, if you don't have one, you must assign an id attribute like this.

<xf:model id="model1" />

Then you can reuse the event handler just calling this code from any trigger or control on your XForms:

                        <xf:dispatch name="next-page" id="model1" />


Hope this helps,

Asunto: [Xsltforms-support] Can you use dispatch to invoke a trigger?

Hi all,

Can you 'call' a trigger by using <xf:dispatch/> ? Say I have a <xf:repeat/> list of items with Next and Prev buttons at the bottom. It's a pretty long list so I want to duplicate the buttons at the top as well but I don't really want to duplicate the event code in these, I just want to get them to activate their respective originals.

I've tried this sort of code below but no luck so far.

<xf:trigger id="next_parent">
            <xf:label>Next Page</xf:label>
            <xf:action ev:event="DOMActivate">
                        <!- lots of stuff here ->
            </xf:action>
</xf:trigger>


<!- this button just 'calls' it's parent
<xf:trigger id="next_dummy">
            <xf:label>Next Page</xf:label>
            <xf:action ev:event="DOMActivate">
                        <xf:dispatch id="next_parent" ev:event="DOMActivate"/>
            </xf:action>
</xf:trigger>

Rgds,
