Question

我有以下代码：

$scope.showTotal = function() {
    $scope.pT = [];
    var iT = 0;
    for (var i = 0; i < $scope.od.length; i++) {
        console.log($scope.od[i]['bpr']);
        iT += $scope.od[i]['bpr'];
        // also tried this -> iT = iT + $scope.od[i]['bpr']
    }
    $scope.pT.push({iTotal: iT});
    console.log($scope.popupTotals);
    $scope.showPopupNow = true;
}

但我不知道为什么它不起作用。如果bpr是例如50和43.1034，那么它会在控制台中记录输出，如iTotal:"050.000043.1034"

我是JavaScript的新手，我直接使用AngularJS启动它。所以请帮我解决JS中的算术运算符。谢谢。

你正在循环中增加i。删除副本i，我怀疑你的$scope.order[i]['baseprice']不是整数。因此，使用parseFloat

将其转换为整数

$scope.showTotal = function(){
        $scope.popupTotals = [];
        var itemtotal = 0;
        for (var i = 0; i<$scope.order.length; i++){
            console.log($scope.order[i]['baseprice']);
            itemtotal += parseFloat($scope.order[i]['baseprice']);
            //also tried this -> itemtotal = itemtotal + $scope.order[i]['baseprice']
            //i++; No need to increment here
        }
        $scope.popupTotals.push({itembasetotal : itemtotal});
        console.log($scope.popupTotals);
        $scope.showPopupNow = true;
    }
