The sound of the singing tube tower is thin, and the night is heavy in the swing yard.

Create a new Learn.vue

And introduce Article.vue and Poetry.vue into Learn.vue

Learn.vue, Article.vue and Poetry.vue in this article are in the same folder.

2. Use with keep-alive

Keep-alive can maintain the state of these components, and if you need to maintain the state of the components, you need to use them with keep-alive

First look at the situation where you need to stay in state instead of using keep-alive.

Create a new Manuscript.vue

Modify Learn.vue

Poetry contribution import Poetry from'. / Poetry.vue'import Manuscript from'. / Manuscript.vue'export default {components: {Poetry, Manuscript}, data () {return {currentComponent: 'Poetry'}} Methods: {changeComponent (type) {if (type = = 1) {this.currentComponent = 'Poetry'} if (type = = 2) {this.currentComponent =' Manuscript'}

Running effect

If you look at the running effect, you will find that after entering the text in the manuscript, you will switch back to the poem, and then go back to the manuscript, the previous manuscript information will be gone.

The reason for this is that every time you switch a new component, Vue creates a new component. Therefore, if you need to save the original component information, use it with keep-alive

Learn.vue after adding keep-alive

Use tags to wrap dynamic components

Poetry contribution import Poetry from'. / Poetry.vue'import Manuscript from'. / Manuscript.vue'export default {components: {Poetry, Manuscript}, data () {return {currentComponent: 'Poetry'}} Methods: {changeComponent (type) {if (type = = 1) {this.currentComponent = 'Poetry'} if (type = = 2) {this.currentComponent =' Manuscript'}
