get-parent

介绍

获取某个非null对象、数组或函数的父对象; To obtain a not null objects, arrays, or function of the parent object;

通过npm引入使用

1. npm install get-parent --save
2. import GPI from "get-parent"; // GPI自己可以定义其它名字
3. GPI.init(objectName, object); // 需要用哪个对象在给他初始化;
4. childObject.getParent(); // 获取父对象
5. object.add(key, value); //对象添加新元素,通过此方法添加的对象、数组、函数仍然可以获取到父对象
6. Array的push/unshift/splice已经改造，增加元素一样可以监听

例子：

  <script>
  import GPI from "get-parent";

  export default {
    name: 'Test',
    mounted(){
      console.log(GPI);
      // ==========Object============
      var obj = {
        a: {
          hi: '123',
          hello: '234'
        },
        b: new String('bcd'),
        array: [1,2,3, {
          aa: 234
        },['a', {b: 'asd'}]]
      }

      console.log("obj --- ", obj);
      GPI.init('obj', obj);

      let t1 = obj.b;
      let t2 = obj.array[3];
      let t3 = obj.array[4][1];
      console.log("t1 --- ", t1);
      console.log("t2 --- ", t2);
      console.log("t3 --- ", t3);
      console.log("t1.getParent() --- ", t1.getParent());
      console.log("t2.getParent() --- ", t2.getParent());
      console.log("t3.getParent() --- ", t3.getParent());
      obj.add('test', {
        'what': 'wow'
      })
      let ww = obj.test;
      console.log(ww.getParent());

      // ==========Array============

      let array = [1,23,4, {
        asd: {
          fff: 2323
        }
      }]

      GPI.init('array', array);

      console.log(array[3]);
      console.log(array[3].getParent());
    }
  }
  </script>

通过script标签引入使用

1. 路径根据自己的文件位置定义
2. let GPI = window.GPI;
3. GPI.init(objectName, object); // 需要用哪个对象在给他初始化;
4. childObject.getParent(); // 获取父对象
5. object.add(key, value); //对象添加新元素,通过此方法添加的对象、数组、函数仍然可以获取到父对象
6. Array的push/unshift/splice已经改造，增加元素一样可以监听

例子：

  // ==========Object============
  let obj = {
    a: 1,
    b: {
      val : 2,
      c: {
        val: 3
      }
    },
    test(a){
      console.log(a);
    },
    d: [1,2,3,4,{
      e: 123
    }],
    e: null,
    f: new String('adf'),
    g: new Number(123)
  }

  let c = obj.b.c;
  let test = obj.test;
  let d = obj.d;
  let GPI = window.GPI;

  GPI.init("obj", obj);
  console.log(obj, "obj");

  console.log("getParent", d.getParent());

  console.log(obj.b.c);
  console.log(obj.b.c.getParent());

  // ==========Array============

  let array = [1,23,4, {
    asd: {
      fff: 2323
    }
  }]

  GPI.init('array', array);

  console.log(array[3]);
  console.log(array[3].getParent());
