vue对象复制方式(深拷贝,多层对象拷贝方式在后面)

    // 对象深拷贝
    obejctCopy() {
      // 源对象小李
      const source = { name: '小李', age: 18, gender: '男', school: '清华大学' }
      // 拷贝小李
      const copy1 = { ...source }
      // 拷贝小李，并修改名字为小张
      const copy2 = { ...source, name: '小张' }
      // 修改源对象
      source.age = 19
      // 查看结果
      console.log(source)
      console.log(copy1)
      console.log(copy2)
    }

      // 源对象小李
      // const source = { name: '小李', age: 18, gender: '男', school: '清华大学' }
      const source = { name: '小李', age: 18, gender: '男', school: '清华大学', more: { a: "test", b: 2, c: {} } }
      // 拷贝小李
      const copy1 = { ...source }
 
      console.log(source === copy1)               // false
      console.log(source.more === copy1.more)     // true

      // 源对象小李
      // const source = { name: '小李', age: 18, gender: '男', school: '清华大学' }
      const source = { name: '小李', age: 18, gender: '男', school: '清华大学', more: { a: "test", b: 2, c: {} } }
      // 拷贝小李
      const copy1 = { ...source, more: { ...source.more } }
 
      console.log(source === copy1)               // false
      console.log(source.more === copy1.more)     // false
