$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 add any property in $param as follows

$param.name = “Adam”;
$param.age = 26;

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

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

Note

• 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.
