Vue project: how to solve the problem that router passes params parameters and data is lost when the page is refreshed

For example, our A page has a button, click the button to pass the data to other pages:

Then we can create a new A.vue file with the following code:

ToB

Export default {

Name:'A'

Data () {

Row: {

Name: 'page A'

}

}

Methods: {

ToB () {

This.$router.push ({

Name:'B'

Params: {

Row: this.row

}

})

}

}

}

Then page B accepts the data from page A:

We can create a new B.vue page:

{{row.name}}

Export default {

Name:'B'

Props: ['row']

}

The reason why we can use the props attribute to receive row is that we enable decoupling of routing parameters by setting props to true in the routing profile:

{

Path:'/ B'

Name:'B'

Props: true

Component: import ('B.vue')

}

But if the user suddenly refreshes the B page data will be lost, how do we generally solve it? There are probably three ways:

The first is to use query query to pass parameters: pass data on page A:

This.$router.push ({

Name:'B'

Query: {

Row: JSON.stringify (this.row)

}

})

B page accepts data:

{{JSON.parse ($route.query.row) .name}}

Second: still use params to pass parameters, but must be combined with localstroage cache

For example, page A:

This.$router.push ({

Name:'B'

Params: {

Row: this.row

}

})

B page accepts data: caches the data during the created life cycle and deletes the cache when the page is destroyed

Export default {

Name:'B'

Data () {

Return {

Row: null

}

}

Created () {

Let rowData = localStorage.getItem ('rowData')

If (rowData) {

This.row = this.$route.params.row

LocalStorage.setItem ('rowData', JSON.stringify (this.$route.params.row))

}

}

BeforeDestory () {

LocalStorage.removeItem ('rowData')

}

}
