All,
I needed the ability for the DisplayCheckbox tag to handle click
actions separate than what happens during form submission. Basically what I
needed to happen was if the user clicks the checkbox, the page gets reloaded
passing in a variable that then executes some CF code.
I didn't find any way of doing this short of just using
CF_DisplayExtraFormContent and just hard coding the stuff I needed, but I
can see a need in our system to handle this in more than one area, and there
are too many benefits to using the Plum custom tags to really have that be a
viable option.
So I thought someone on the list might find this useful.
I have tested this in FireFox and IE. I guess browser compatibility
will really be determined by what JS you decide to call in the event
handler.
If you find any problems let me know.
Change:
Added onClick attribute.
Tag Call:
<cf_DisplayCheckBox column="autopath" label="Autopath"
checkedValue="1" uncheckedValue="0"
onClick="if(this.checked){document.location='#Application.absoluteUrlRoot#/a
dmin/Menu/MenuEditForm.cfm?menu_id=#menu_id#&autopath=true'}">
Note: you can have the onClick attribute send a js function, if I
did it in this case I would need to send through the
application.absoluteurlroot through as well as either the object or the
object.checked property.
Tag Code:
<cfsetting enablecfoutputonly="Yes">
