This is the simplest, but not necessarily the prettiest way. Not a hack, just not pretty with the standard Javascript confirm popup dialog.
1. Set your UI Action to run client-side by checking the "Client" field
2. Set the "Onclick" field to be "uFunctionNameClient();"
3. add this template to the "Script" field:
//client function that runs "onclick"
function uFunctionNameClient() {
if(confirm("Are you sure you want to ***?")) {
gsftSubmit(null, g_form.getFormElement(), "***u_action_name_goes_here***"); //MUST call the "Action name" for this UI Action
}
}
//code that runs on server once confirmed
//ensure call to server-side function with no browser errors
(function() {
if (typeof window == "undefined") {
//server-side code goes here
}
})();
The "uFunctionNameClient" function name must be the same in the "Onclick" and "Script" fields. Also, the "***u_action_name_goes_here***" in the "Script" field must match the value in the "Action name" field on the UI Action record.
There are ways of making the confirm popup prettier, one of them being "Simple Modal Confirm" UI Page
