除了页面重载方法(闪烁)，没有一个适合我(:键没有工作)。

我发现这个方法从旧vue.js论坛，这是为我工作:

https://github.com/vuejs/Discussion/issues/356

<template>
    <div v-if="show">
       <button @click="rerender">re-render</button>
    </div>
</template>
<script>
    export default {
        data(){
            return {show:true}
        },
        methods:{
            rerender(){
                this.show = false
                this.$nextTick(() => {
                    this.show = true
                    console.log('re-render start')
                    this.$nextTick(() => {
                        console.log('re-render end')
                    })
                })
            }
        }
    }
</script>

<my-component :key="uniqueKey" />

同时使用。$set(obj，'obj_key'，value) 并且每次更新object (obj)值时更新uniqueKey 对于每一次更新this. uniquekey++

这对我来说很管用

如果您正在使用路由器视图或Vue路由器，您可以直接使用关键功能

<router-view :key="$route.path"></router-view>

这将告诉路由器视图在每次路径改变时重新渲染页面。

使用vm。美元(varName,价值)。

在Change_Detection_Caveats中查看详细信息

Why?

.．.需要强制更新吗?

也许你没有在最好的状态下探索Vue:

要使Vue自动对值更改作出反应，必须在数据中初始声明对象。如果没有，则必须使用Vue.set()添加它们。

请参阅下面演示中的注释。或者在JSFiddle中打开相同的演示。

new Vue({ el: '#app', data: { person: { name: 'Edson' } }, methods: { changeName() { // because name is declared in data, whenever it // changes, Vue automatically updates this.person.name = 'Arantes'; }, changeNickname() { // because nickname is NOT declared in data, when it // changes, Vue will NOT automatically update this.person.nickname = 'Pele'; // although if anything else updates, this change will be seen }, changeNicknameProperly() { // when some property is NOT INITIALLY declared in data, the correct way // to add it is using Vue.set or this.$set Vue.set(this.person, 'address', '123th avenue.'); // subsequent changes can be done directly now and it will auto update this.person.address = '345th avenue.'; } } }) /* CSS just for the demo, it is not necessary at all! */ span:nth-of-type(1),button:nth-of-type(1) { color: blue; } span:nth-of-type(2),button:nth-of-type(2) { color: red; } span:nth-of-type(3),button:nth-of-type(3) { color: green; } span { font-family: monospace } <script src="https://unpkg.com/vue"></script> <div id="app"> <span>person.name: {{ person.name }}</span><br> <span>person.nickname: {{ person.nickname }}</span><br> <span>person.address: {{ person.address }}</span><br> <br> <button @click="changeName">this.person.name = 'Arantes'; (will auto update because `name` was in `data`)</button><br> <button @click="changeNickname">this.person.nickname = 'Pele'; (will NOT auto update because `nickname` was not in `data`)</button><br> <button @click="changeNicknameProperly">Vue.set(this.person, 'address', '99th st.'); (WILL auto update even though `address` was not in `data`)</button> <br> <br> For more info, read the comments in the code. Or check the docs on <b>Reactivity</b> (link below). </div>

要掌握Vue的这一部分，请查看关于反应性-更改检测警告的官方文档。这是一本必读的书!

我找到了一个办法。这有点俗气，但很管用。

vm.$set("x",0);
vm.$delete("x");

其中vm是视图模型对象，x是一个不存在的变量。

Vue.js会在控制台日志中抱怨这个问题，但它确实会触发所有数据的刷新。使用版本1.0.26进行测试。
