Html 如何使用angularjs在表格网格中根据公式计算金额

am计算员工薪资明细，basic有默认金额，并使用公式根据基本值计算剩余hr、ta等 我已经试过了 am拆分公式和传递值

html

斯诺
名称
数量
公式
总价值
{{$index+1}}
{{e.Name}}
{{e.Amount}}
{{e.Formula}}
{{e.TotalValue}}

棱角的

$scope.EmployeeData = [{ Id: 1, Name: 'Basic', Amount: 100, Formula: '', TotalValue: 0 }, { Id: 2, Name: 'HR', Amount: 0, Formula: '<Basic>*10/100', TotalValue: 0 },
    { Id: 3, Name: 'TA', Amount: 0, Formula: '<Basic>+500', TotalValue: 0 }]

$scope.Employees = [];
var data = $scope.EmployeeData;
for (i = 0; i < data.length; i++) {
    if (data[i].Formula !== "") {
        $scope.Matches = data[i].Formula.replace("<", "").replace(">", ",").replace("+", "+,").replace("*", "*,").replace("-", "-,").split(',');
        $scope.Item1 = $scope.Matches[0];
        $scope.arithmeticOperator = $scope.Matches[1];
        $scope.Item2 = $scope.Matches[2];
        if ($scope.Item1 == 'Basic') {
            if ($scope.arithmeticOperator == '*') {
                data[i].TotalValue = (($scope.Value) * (eval($scope.Item2)));
            }
            else if ($scope.arithmeticOperator == '+') {
                data[i].TotalValue = (($scope.Value) + (eval($scope.Item2)));
            }
            else if ($scope.arithmeticOperator == '/') {
                data[i].TotalValue = (($scope.Value) / (eval($scope.Item2)));

            }
            else if ($scope.arithmeticOperator == '-') {
                data[i].TotalValue = (($scope.Value) - (eval($scope.Item2)));

            }
        }
//...
//like basic am given conditions for HR,TA 
    }
    else {
        $scope.Value = data[i].Amount;
    }

    //pushing data in table
    $scope.Employees.push(data[i]);
}

$scope.EmployeeData=[{Id:1，名称：'Basic'，金额：100，公式：''，总值：0}，{Id:2，名称：'HR'，金额：0，公式：'*10/100'，总值：0}，
{Id:3，名称：'TA'，金额：0，公式：'+500'，总值：0}]
$scope.Employees=[]；
var数据=$scope.EmployeeData；
对于（i=0；i

能够通过使用此项计算总价值， 但这是计算公式的正确方法吗， 如果像

+100++
，++
++

这样的公式， 如何在算术表达式上计算公式 我的代码将仅限于此表达式

“*100”

$scope.EmployeeData = [{ Id: 1, Name: 'Basic', Amount: 100, Formula: '', TotalValue: 0 }, { Id: 2, Name: 'HR', Amount: 0, Formula: '<Basic>*10/100', TotalValue: 0 },
    { Id: 3, Name: 'TA', Amount: 0, Formula: '<Basic>+500', TotalValue: 0 }]

$scope.Employees = [];
var data = $scope.EmployeeData;
for (i = 0; i < data.length; i++) {
    if (data[i].Formula !== "") {
        $scope.Matches = data[i].Formula.replace("<", "").replace(">", ",").replace("+", "+,").replace("*", "*,").replace("-", "-,").split(',');
        $scope.Item1 = $scope.Matches[0];
        $scope.arithmeticOperator = $scope.Matches[1];
        $scope.Item2 = $scope.Matches[2];
        if ($scope.Item1 == 'Basic') {
            if ($scope.arithmeticOperator == '*') {
                data[i].TotalValue = (($scope.Value) * (eval($scope.Item2)));
            }
            else if ($scope.arithmeticOperator == '+') {
                data[i].TotalValue = (($scope.Value) + (eval($scope.Item2)));
            }
            else if ($scope.arithmeticOperator == '/') {
                data[i].TotalValue = (($scope.Value) / (eval($scope.Item2)));

            }
            else if ($scope.arithmeticOperator == '-') {
                data[i].TotalValue = (($scope.Value) - (eval($scope.Item2)));

            }
        }
//...
//like basic am given conditions for HR,TA 
    }
    else {
        $scope.Value = data[i].Amount;
    }

    //pushing data in table
    $scope.Employees.push(data[i]);
}
