AngularJS - 如何為數組中的每個對象添加新屬性

Question

我想學習如何將范圍變量推送到數組的每個項目中。

這就是我所擁有的：

$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;
        });
};

該數組是 $scope.AgendaItems。 它由excel數據填充。

它包含了：

我必須將名為 $scope.meetingId 的變量的值推送到每個記錄，以便在推送后數組內容為：

$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}

有人可以告訴我如何實現這一目標嗎？

謝謝你，埃拉斯莫

如果您實際上只是想在每次迭代中添加 ID“49490”，那么就可以了。

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