I wish to have the user make a choice in a select box and then in a Dymamic Action which waits for the select box to be changed it reads the select box value that was chosen
回答1:
Create a Dynamic Action which fires on "Change". As a true action:
- Action: "Set Value"
- Set Type: "JavaScript Expression"
- Javascript Expression:
apex.item(this.triggeringElement).getValue() - Choose the item to set the value with under "Affected Elements"
This will get the value of the element which triggered the change event and will set it to the affected element you choose. Note though: the value of the select list will be the underlying return value (eg ID), NOT the display value.
