您好我是Angular-Js的初学者，我正在尝试显示表格视图并提供添加新记录的功能，但问题是当我尝试添加新记录数据时未插入且我的代码是下面。
我犯了什么错误？
有人可以帮助我。

//add to the real data holder

id++;
};
//remove to the real data holder
$scope.removeItem = function removeItem(row) {
var index = $scope.rowCollection.indexOf(row);

答案 0 :(得分：0)
您需要将功能更改为：
//add to the real data holder
$scope.addRandomItem = function() {
$scope.rowCollection.push(generateRandomItem(id));
id++;
};
//remove to the real data holder
$scope.removeItem = function(row) {
var index = $scope.rowCollection.indexOf(row);
if (index !== -1) {
$scope.rowCollection.splice(index, 1);
}
}
当您使用语法$scope.functionName = function()声明范围内的函数时，您不需要在function()之后右侧编写functionName。
