Confirmation prompt in custom app?

[JustinL]

I think i've seen before some apps will have a pop-uip prompt to confirm that a user wants to proceed with some action (e.g., delete something). Might be the easiest way to do what i need. Anyone have example code for how to do that?

The simplest way, I expect, would be to include an additional page to confirm the action, such as a deletion. The more complex option could be a modal iFrame.... but the extra page is likely the simpler path.

I use this in a bunch of cases...

input "clearMap", "bool", title: "Clear Version Map", defaultValue:false, submitOnChange:true
            if(clearMap) {
                input "clearMap2", "bool", title: "<b>Are you sure</b>", defaultValue:false, submitOnChange:true, width:3
                if(clearMap2) {
                    state.versionMap = [:]
                    app.updateSetting("clearMap2",[value:"false",type:"bool"])
                    app.updateSetting("clearMap",[value:"false",type:"bool"])
                }
            } else {
                app.updateSetting("clearMap2",[value:"false",type:"bool"])
            }
