I am learning Vue and trying to complete a task myself.
I would like to find out how to run v-for loop on @click so that on initial state, only "city" template appears, and on each click, tour template renders with related tours.
let EventBus = new Vue();
Vue.component('cities', {
name: 'Listings',
props: ['city','tour'],
template: `
<div>
<div class='city-list box'>
<city v-for='city in cities' :id='city.id' :key='city.id' :city='city' :tour='tour' @click.native='select(city)'></city>
</div>
<div class='tour-list box'>
<tours v-for='tour in filter(tours)' :id='tour.id' :key='tour.id' :tour='tour'></tours>
</div>
</div>
`,
data() {
return {
cities: [
{id:1, name: 'Istanbul'},
{id:2, name: 'Paris'},
{id:3, name: 'Barça'},
{id:4, name: 'Rome'},
{id:5, name: 'Mars'}
],
tours: [
{id:1, cid:1, name: 'Bosphorus'},
{id:2, cid:2, name: 'Eiffel'},
{id:3, cid:3, name: 'La Sagrada Familia'},
{id:4, cid:4, name: 'Colosseum'},
{id:5, cid:5, name: 'Mars Canyon'},
{id:6, cid:1, name: 'Sultanahmet'},
{id:7, cid:2, name: 'Champs-Élysées'},
{id:8, cid:3, name: 'Casa Mila'},
{id:9, cid:4, name: 'Trevi Fountain'},
{id:10, cid:5, name: 'Mars Desert'},
]
};
},
methods: {
select(city) {
console.log('select');
EventBus.$emit('filter', city);
},
filter(tours) {
console.log('filter');
EventBus.$on('select', ()=>{
cid = this.city.id;
return tours.filter(function(tour) {
return tour.cid == cid;
});
});
},
},
components: {
'city': {
name: 'City',
props: ['city'],
template: `
<div :id="[city.name.toLowerCase()]" :class="[city.name.toLowerCase()]">
<h1>{{ city.name }}</h1>
</div>`
},
'tour': {
name: 'Tour',
props: ['city', 'tour'],
template: `
<div :class="['tour-' + tour.id]" :id="[city.name.toLowerCase() + '-tours']" :refs="city.id" :data-id="city.id">
{{ tour.name }}
</div>
`,
},
},
});
new Vue({
el: '#root'
}); body {
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
}
.box {
margin: 48px auto;
max-width: 1024px;
display: flex;
justify-content: center;
align-items: center;
}
.box h1 {
font-size: 1.1rem;
color: #41f;
}
.box > div {
padding: 24px;
margin: 12px;
width: 20%;
min-height: 100px;
border-radius: 2px;
font-size: 1.15rem;
line-height: 1;
}
.box > div:nth-child(1)
{background-color: #ffb3ba;}
.box > div:nth-child(2)
{background-color: #ffdfba;}
.box > div:nth-child(3)
{background-color: #ffffba;}
.box > div:nth-child(4)
{background-color: #baffc9;}
.box > div:nth-child(5)
{background-color: #bae1ff;}<script src="https://unpkg.com/[email protected]/dist/vue.js"></script>
<div id="root">
<cities></cities>
</div>I am also interested in the state of art, if it is a good practice to have two templates together (which are related), and connect this model with a db and router (city/tour-list). Or how would you approach to a such case (I guess jsfiddle should be self explanatory).
As a side note I have tried adding tour as a child to parent component [jsfiddle] where I filter results by ID, I am not sure if this way is a better approach both for components and filtering results in the sense of architecture.
