To extend the controller and lifecycle methods in UI5, you can follow these steps:
Create a new JavaScript file for your extension code and add it to your project.
In your extension code, define your custom controller extension that extends the original controller.
sap.ui.define([
"sap/ui/core/mvc/Controller"
], function(Controller) {
"use strict";
return Controller.extend("my.app.controller.CustomController", {
// Define your custom methods here
onBeforeRendering: function() {
// Call the original onBeforeRendering method
Controller.prototype.onBeforeRendering.apply(this, arguments);
// Add your own logic here
},
onAfterRendering: function() {
// Call the original onAfterRendering method
Controller.prototype.onAfterRendering.apply(this, arguments);
// Add your own logic here
}
});
});
<mvc:View xmlns:mvc="sap.ui.core.mvc"
xmlns="sap.m"
controllerName="my.app.controller.CustomController">
<!-- Your view content here -->
</mvc:View>
sap.ui.define([
"sap/ui/core/mvc/XMLView"
], function(XMLView) {
"use strict";
// Instantiate the view
XMLView.create({
viewName: "my.app.view.MyView",
// Add additional parameters here if needed
}).then(function(view) {
// Add the view to the DOM
view.placeAt("content");
});
});
With these steps, you have extended the controller and lifecycle methods of your UI5 view. You can add additional custom methods and override other methods as needed.
