With the declarative
The declarative component support is not activated by default but must be enabled via the bootstrap. To do this, the following attribute must be added to the bootstrap script to load the
ComponentSupport module (see the figure Using the Declarative API):
run function of
sap/ui/core/ComponentSupport is called automatically once the module has been loaded. It scans the DOM for HTML elements containing a special data attribute named
data-sap-ui-component. All DOM elements marked with this data attribute will be regarded as container elements into which a
sap/ui/core/ComponentContainer is inserted.
Additional data attributes are then used to define the constructor arguments of the created component container instance. In the example shown, the following data attributes are specified:
This attribute is used to pass the Id for the component container instance to be created.
data-nameattribute contains the name of the component to be instantiated.
The object specified for the
data-settingsattribute is passed to the component instance when it is created. In the example, it is used to set the component instance Id.
ComponentSupport module enforces asynchronous module loading of the component with "manifest first". This means that the
manifest.json file is loaded before evaluating the component to optimize loading behavior (see above).
