问题
My code is like this :
<template>
<a href="javascript:" class="btn btn-block btn-success" @click="addFavoriteStore($event)">
<span class="fa fa-heart"></span> Favorite
</a>
</template>
<script>
export default{
props:['idStore'],
mounted(){
this.checkFavoriteStore()
},
methods:{
addFavoriteStore(event){
alert('tost');
event.target.disabled = true
const payload= {id_store: this.idStore}
this.$store.dispatch('addFavoriteStore', payload)
setTimeout(function () {
location.reload(true)
}, 1500);
},
checkFavoriteStore(){
const payload= {id_store: this.idStore}
this.$store.dispatch('checkFavoriteStore', payload)
setTimeout(function () {
location.reload(true)
}, 1500);
//get response here
}
}
}
</script>
When the script executed, it will call checkFavoriteStore method first
By checkFavoriteStore method, it will call action on the vuex store
And the results will return the response
How to I get the response?
UPDATE
My action on the vuex store like this :
import { set } from 'vue'
import favorite from '../../api/favorite'
import * as types from '../mutation-types'
// actions
const actions = {
checkFavoriteStore ({ dispatch,commit,state },payload)
{
favorite.checkFavorite(payload,
data => {
commit(types.CHECK_FAVORITE_SUCCESS)
},
errors => {
commit(types.CHECK_FAVORITE_FAILURE)
console.log(errors)
}
)
}
}
// mutations
const mutations = {
[types.CHECK_FAVORITE_SUCCESS] (state){
state.addStatus = 'success'
},
[types.CHECK_FAVORITE_FAILURE] (state){
state.addStatus = 'failure'
}
}
export default {
actions,
mutations
}
And the api like this :
import Vue from 'vue'
import Resource from 'vue-resource'
Vue.use(Resource)
export default {
// api check favorite exist or not
checkFavorite (favorite, cb, ecb = null ) {
Vue.http.post(window.Laravel.baseUrl+'/member/store/favorite/check-favorite', favorite)
.then(
(resp) => cb(resp.data),
(resp) => ecb(resp.data)
);
}
}
回答1:
if your returning a result then assign the call to a variable so tyr:
var res = this.$store.dispatch('checkFavoriteStore', payload);
then you can get access to the response via the var res. I believe the events will return it back to you
MORE query:
just a little question on this.
If your getting the store ID and passing this to the component as a prop. So surely you could also pass in another prop that tells if the store has already been liked? So getting this data via the db call to the view, thus saving having to do a check after its loaded, so something like:
<favorite-button :storeid="23" :favorited="true"></favorite-button>
So using the favorited property to change the button accordingly?, so need for the checkFavoriteStore call and saving time on additional http request etc
Don't know your code or what's its doing etc but just a thought??
EDIT AFTER ADDITION INFO ADDED
OK so can you change your http request to say:
Vue.$http.post(window.Laravel.baseUrl+'/member/store/favorite/check-favorite', favorite)
.then((response) => {
console.log('success')
console.log(response.data);
return response.data;
}, (response) => {
console.log('success');
console.log(response);
return response;
});
i have added console.logs so we can see whats happing. let's see if this helps?
also try adding a return in front of, as it needs to return to its original caller
return favorite.checkFavorite(payload,
data => {
commit(types.CHECK_FAVORITE_SUCCESS)
},
errors => {
commit(types.CHECK_FAVORITE_FAILURE)
console.log(errors)
}
)
Also a comment, do you need all this complexity for just this simply check, i don't know the rest of your code and construction, but as suggested passing in the state of the button as a prop (as above) and just handle the isFavorited call within the compnent itself, so no need to use a store fo this simple request??
EDIT 2:
if you need to return another wahy with promise try::
Vue.$http.post(window.Laravel.baseUrl+'/member/store/favorite/check-favorite', favorite)
.then((response) => {
console.log('success')
resolve(response.data);// replace the return with resolve?
}, (response) => {
console.log('success');
console.log(response);
reject(response.data);// replace the return with reject?
});
Might be the issue??

below is a solution that does not require a store, just a thought might be handy:
PHP Page:
<favorite-button
:storeid="{{$storeid}}"
:favorited="{{$isFavorited}}"
:url="{{route('check-favorite')}}"
></favorite-button>
<script>
(function(){
import favoriteButton from 'favorite-button';
new Vue({
el : '#app',
components : {
favoriteButton
}
});
})();
</script>
Then the component
<style lang="sass">
.heart {
color: grey;
&.is-favorited {
color: red;
}
}
</style>
<template>
<button class="btn btn-block btn-success" @click.prevent="udateFavorited($event)">
<span class="heart" :class="{'is-favorited' : this.favorited }">&heart;</span> <span :text="{this.favoriteText}"></span>
</button>
</template>
<script>
import axios from 'axios';
export default{
props : {
storeid : {
type: Number,
required : true,
default : () => {}
},
favorited : {
type: Boolean,
required : false,
default : false
},
url : {
type: String,
required : true
}
},
computed : {
favoriteText : function(){
return (this.favorited) ? 'Unfavorite' : 'Favorite';
}
},
methods:{
updateFavorited(event){
//-- so update the db so if fasle update to true else if true = false
axios.post(this.url, this.storeid)
.then(response => {
//-- all ok update the visual button
this.favorited = response.data.favorited
})
.catch(error => {
console.log('error');
console.log(error);
this.favorited = response.data.favorited
});
}
}
}
</script>
So basically on initial loading the page, it passes the storeid, and whether the store is or not already favorited, as well as the url action on click event
Then when a user clicks the user clicks the button it will update the DB and then the text and the colour of the heart, depending on the result
Just another idea/solution to consider if having issues??
