I want to check in a script in a condition if a CheckBox is
is checked, but I don’t know how to access properties of a widget with JavaScript code. A widget inside an app can be accessed like this: sap.ui.getCore().byId(“Screenname–WidgetID”) . after the dot you can select a method, but how do I access a widget property?

Thanks in advance

Greetings Leonid

Hello Leonid,

with sap.ui.getCore().byId(“Screenname–WidgetID”).mProperties you can see all available properties of the widget.
With sap.ui.getCore().byId(“Screenname–WidgetID”).getProperty(propertyName) you can get the value of a specific property.
This is the generic way, but each property has a specific getter and setter.

For your example of a CheckBox you could do this:
sap.ui.getCore().byId(“Screenname–WidgetID”).getProperty(“selected”) which will return either true or false depending on whether or not the CheckBox is currently selected.
We recommend using the selected-specific getter .getSelected()

Please follow the official OpenUI5 documentation for more information on the available properties and methods: https://openui5.hana.ondemand.com/api/sap.m.CheckBox
