如果对于类的成员函数,则应该是类.prototype.funName,对于实例的成员,我们可以通过在实例上添加函数来重写方法。 首先我们这个函数是所有函数的方法,所以它必须在Function.prototyp上添加一个新的函数Hook,它的逻辑应该是首先查找函数的名称,如果得到了,则直接改写在指定对象上的函数实现。但如果这个函数是匿名函数,我们需...
constructor () { console.log('testfn2') } } 1. 2. 3. 4. 5. 6. 7. 8. 这里产生了报错,Testfn2是在定义之前使用的,这与没有声明是不一样的,比如看下边这个 console.log(testfn3) // Error in created hook: "ReferenceError: testfn3 is not defined" 1. testfn3是未定义,这样一对比就提现...
Vue.set(vm.items, indexOfItem, newValue) Array.prototype.splice【*】 vm.items.splice(indexOfItem, 1, newValue) 使用Vue.set(object, key, value) 方法向“嵌套对象”添加响应式属性,例如: Vue.set(vm.userProfile, 'age', 27) 有时你可能需要为已有对象赋予多个新属性: vm.userProfile = Object....
