get-parent v1.1.3

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());
