Question

Upon returning from a different page, data on the Vue.js form page is unexpectedly lost

On my Vue.js page, there is a large textarea element. However, I am facing an issue where if the user taps on "Settings," opens the Settings page and then goes back to the original page, all of the data in the textarea disappears. I am looking for a solution that will prevent this data loss without having to save it in a database. Does anyone know of a simple way to achieve this?

I am utilizing Vue Router for navigation.

Is there a feature within Vue Router that functions similar to a modal window (specifically for mobile applications) that can be closed without losing any data underneath?

javascript vue.js vue-router

To enhance the performance, I suggest encoding the form ID into the route path and utilizing props=true to pass the ID as a component prop:

// router.js
export default new VueRouter(
  routes: [
    {
      path: "/form/:id",
      name: "form",
      component: () => import("@/components/MyForm.vue"),
      props: true
    }
  ]
)

// MyForm.vue
export default {
  props: {
    id: {
      type: [Number, String],
      default: 0,
      required: true,
    },
  },
  data() {
    return {
      text: "The text " + this.id,
    };
  },
}

Furthermore, you can optimize by using <keep-alive> for caching views and setting the route's full path as the key for router-view:

<keep-alive>
  <router-view :key="$route.fullPath" />
</keep-alive>
