AngularJS - 如何为数组中的每个对象添加新属性

Question

I would like to learn how to push a scope variable into each item of an array.

This is what I have:

$scope.ProcessExcel = function (data) {

        //Read the Excel File data.
        var workbook = XLSX.read(data, {
            type: 'binary'
        });

        //Fetch the name of First Sheet.
        var firstSheet = workbook.SheetNames[0];

        //Read all rows from First Sheet into an JSON array.
        var excelRows = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[firstSheet]);

        //Display the data from Excel file in Table.
        $scope.$apply(function () {
            $scope.AgedaItems = excelRows;
        });
};

The array is $scope.AgendaItems. It gets populated by excel data.

It contains:

I have to push the value of a variable named: $scope.meetingId, to each record so that after pushing it the array contents are:

$scope.AgedaItems: Array(5)
0: {MeetingId: "49490", AgendaItem: "1", LegistarID: "61613", Title: "Title#1", __rowNum__: 1}
1: {MeetingId: "49490", AgendaItem: "2", LegistarID: "60826", Title: "Title#2", __rowNum__: 2}
2: {MeetingId: "49490", AgendaItem: "3", LegistarID: "61168", Title: "Titel#3", __rowNum__: 3}
3: {MeetingId: "49490", AgendaItem: "4", LegistarID: "61612", Title: "Title#4", __rowNum__: 4}
4: {MeetingId: "49490", AgendaItem: "5", LegistarID: "60646", Title: "Title#5", __rowNum__: 5}

Would it be possible that someone can show me how to achieve this?

Thank you, Erasmo

Answer 1

If you are literally just wanting to add the ID "49490" to each iteration, then this will do it.

$scope.AgedaItems.forEach(function(item){
    item.MeetingId = "49490";
})
