$param

$param is a parameter object that sends arbitrary data to the next UI screen. Scope is up to the next UI screen.
You can pass data to the destination screen by adding any property to the $param object within the action that executes the screen transition, as follows:

$param.name = "Adam";
$param.age = 26;
$fn.nextUI(uiCode);

You can receive $param in the onload action of the target UI.

const name = $param.name;
const age = $param.age;

Note

• $param can only be passed to the next screen during screen transitions in actions.
• When passing $param to the next screen, you must write the process in the following order within the same action:
  1. Add any property to $param
  2. Transition to the screen with $fn.nextUI(uiCode)
• Note that an error will occur if the memory limit in the action is reached when setting data in $param.
• URL parameters can be received as "$param.parameter name".
  For example, if the parameter name is "id", the parameter value can be received in "$param.id".
  For more information on passing URL parameters, please see the Application URL tips.
