在Javascript中将变量与变量值组合

问题描述

我试图在 Angular javascript(一个简化的代码)中做这样的事情:

I am trying to do something like this in Angular javascript (a simplified code):

var modelName = "date";

if (attrs.hasOwnProperty('today')) {
   scope.modelName = new Date();
}

在上面，我实际上希望 scope.modelName 自动成为 scope.date.如何将 modelName 变量解析为其值?

In the above, I actually want scope.modelName to become scope.date automatically. How can I parse the modelName variable to its value?

推荐答案

您可以使用方括号访问对象的属性.

You can access properties of objects using square brackets.

var modelName = "date";

if (attrs.hasOwnProperty('today')) {
   scope[modelName] = new Date();
}
