如何在Angular2中使用另一个组件中的变量 [英] How to use a variable from a component in another in Angular2

问题描述

I was wondering if it is possible to use variable values from one component into another one without having to use the template of the first one, just need the value of the variable nothing else. Is it possible?

解决方案

Yes possible, you can use the @Input() method or use write get method like below

export class Demo {
    const sum = 10;

    get SumValue() {
        return this.sum;
    }
}

---

import-->Demo

export class Demo2 {
   private sum: number;
   this.sum = Demo.SumValue();
}
