I am new to qml and javascript technologies. I need sample example on push and pop operations on the array. For example, how can I push 3 variables into the array list in QML at a time. I want the output to be like below [{"A001", 1, "Item1"}, {"A002", 2, "Item2"}]. I have started with sample code but could not able to complete the logic in Component.onCompleted.
Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
property var object: ({})
property var list: []
property string str1: "A001"
property int value1: 1
property string item1: "Item1"
property string str2: "A002"
property int value2: 2
property string item2: "Item2"
Component.onCompleted: {
//1. Frame the object {str1, value1, item1}
//2. Push to the array using push operation
//3. The output of the array to be [{"A001", 1, "Item1"}]
//4. Frame the object {str2, value2, item2}
//5. Push to the array using push operation
//6. The output of the array to be [{"A001", 1, "Item1"},{"A002", 2, "Item2"}]
//7. Do pop operation on the array
//8. The output of the array to be [{"A001", 1, "Item1"}]
//9. Do pop operation on the array
//10. The output of the array to be []
}
}
It looks like you want an array of objects. In javascript, objects are key/value pairs. So you have to create them something like this:
var obj1 = {"str": str1, "value": value1, "item": item1}
var obj2 = {"str": str2, "value": value2, "item": item2}
Then you can push or pop them onto your array:
var arr = [];
arr.push(obj1);
arr.push(obj2);
arr.pop();
arr.pop();
