XForms/Select All

WARNING THIS EXAMPLE IN DEVELOPMENT Motivation You would like to be able to select all rows in a table using a single trigger. Approach You can put a list of items in a table and have a single column that has a checkbox in it. You can then use the index function to change the selected item.

I have tried to use the current() function inside the repeat like this: <xf:repeat> <xf:setvalue ref="current()/@selected" value="'false'" /> </xf:repeat> but with no luck. If anyone knows how to get this working, please let us know. Thanks - Dan Alternate Way Note: <xf:repeat> does not work inside <xf:action>. Here is the workaround for this. <xf:instance id="count"> <count/> </xf:instance> <xf:bind nodeset="instance('count')" type="xs:integer" /> <xf:trigger> <xf:label>Select all repeat</xf:label> <xf:action ev:event="DOMActivate"> <xf:setvalue ref="instance('count')" value="0" /> <xf:action while="instance('count') < count(item)"> <xf:setvalue ref="instance('count')" value="instance('count') + 1" /> <xf:setvalue ref="item[number(instance('count'))]/@selected" value="'true'" /> </xf:action> </xf:action> </xf:trigger> Google Maps Graph Viewer
