Vue.js disable component during ajax request

Question

I\'m looking for a simple solution for the following problem:

I have a Vue component button with which I can make an ajax request. I would like to disable this butto

Answer 1

State.js:

state: {
  pendingRequest: false
},
actions: {
  fetchRequest: async function(context) {
    context.state.pendingRequest = true
    let req = await fetch(url)
    let data = await req.json()
    context.state.pendingRequest = false
  }
}

Component.vue:

<button :disabled='$store.state.pendingRequest' @click="$store.dispatch('fetchRequest')">Button</button>

I found another solution: It automatically generates a vuex module for the registered endpoints, watch those endpoints via axios interceptors and sets the proper 'pending' state values based on the status of the related requests.

Sounds like you want your action to set (commit) a flag when it starts and then clear it when it ends.

Try something like this in Vuex...

state: {
  loading: false
},
mutations: {
  isLoading (state) {
    state.loading = true
  },
  doneLoading (state) {
    state.loading = false
  }
},
actions: {
  doAjaxRequest ({ commit }) {
    commit('isLoading')
    return doSomeAjaxRequest().then(res => {
      // success
    }).catch(err => {
      // oh noes
    }).finally(() => {
      commit('doneLoading')
    })
  }
}

Now in your component, you can map the loading state and use it to disable your button, eg

<template>
  <button :disabled="loading" @click="doAjaxRequest">Do AJAX!</button>
</template>
<script>
  import { mapState, mapActions } from 'vuex'
  export default {
    computed: mapState(['loading']),
    methods: mapActions(['doAjaxRequest'])
  }
</script>

---

Alternatively, you can maintain the progress of the request within your component if your action returns a promise (as above). For example, say your button has

<button :disabled="loading" @click="doTheThing">Do the thing!</button>

and

data () {
  return { loading: false }
},
methods: {
  doTheThing() {
    this.loading = true
    this.$store.dispatch('someAjaxActionThatReturnsAPromise').finally(() => {
      this.loading = false
    })
  }
}
