What I am trying to accomplish: I have some filters that display on a page to filter the products that display on the page. In mobile, I want to hide these filters behind a button that, once pressed, will show the filters in a slide out menu from the side.
While I can duplicate the same components on the page twice, the components are not the exact same instance, that is, clicking on a filter will trigger that function to filter the products on the page, but it sets its own data attributes, which I am using to say "if data attribute 'selected' is true, add a 'selected' class to the component. When I resize the window, the other instance of the component does not have the 'selected' data attribute marked as 'true'.
I expect this, because, from the docs:
Notice that when clicking on the buttons, each one maintains its own, separate count. That’s because each time you use a component, a new instance of it is created.
...but what would be the best way to do this?
I played around with the idea of just setting a class 'mobile' on the component, and the .mobile css would style the components differently, but I need for it to break out where it is nested.
e.g.
<body>
<header>
<!-- desktop -->
<guitar-filters>
<header>
<!-- mobile -->
<guitar-filters>
</body
Here is my Vue component 'guitar-filters' that displays several components called 'instrument-filter':
Vue.component('guitar-filters', {
data: function() {
return {
isMobile: false
}
},
mounted: function() {
var comp = this;
this.setIsMobile();
window.addEventListener('resize', function() {
comp.setIsMobile();
});
},
methods: {
setIsMobile: function() {
this.isMobile = (window.innerWidth <= 900) ? true : false;
}
},
template: `
<ul class="filters" :class="{mobile: isMobile}">
<li>
All
</il>
<li>
Series
<ul>
<instrument-filter filter-by="series" filter="All">All</instrument-filter>
<instrument-filter filter-by="series" filter="Frontier">Frontier</instrument-filter>
<instrument-filter filter-by="series" filter="Legacy">Legacy</instrument-filter>
<instrument-filter filter-by="series" filter="USA">USA</instrument-filter>
</ul>
</li>
<li>
Body Shape
<ul>
<instrument-filter filter-by="bodyType" filter="All">All</instrument-filter>
<instrument-filter filter-by="bodyType" filter="Concert">Concert</instrument-filter>
<instrument-filter filter-by="bodyType" filter="Concertina">Concertina</instrument-filter>
<instrument-filter filter-by="bodyType" filter="Concerto">Concerto</instrument-filter>
<instrument-filter filter-by="bodyType" filter="Orchestra">Orchestra</instrument-filter>
</ul>
</li>
</ul>
`
});
The instrument-filter component:
Vue.component('instrument-filter', {
data: function() {
return {
selected: false
}
},
props : [
'filterBy',
'filter'
],
methods: {
addFilter: function() {
this.$root.$emit('addFilter',{filterBy: this.filterBy,filter: this.filter});
},
clearFilter: function() {
this.$root.$emit('clearFilter',{filterBy: this.filterBy,filter: this.filter});
}
},
template: `
<li :class="{ 'selected' : selected }" @click="selected = !selected; selected ? addFilter() : clearFilter()"><slot></slot></li>
`
});
.css:
ul.filters > li > ul > li.selected::before {
content: "✔️";
...
}
The goal is to have a filter have the 'selected' class in both instances. If I click on 'concert' body shape, and then resize the window to mobile breakpoint, the other instance of that filter component will be selected also.
EDIT: I could hack this. I could move one instance of the component with javascript, but I'm learning Vue, and want to do this the Vue way and best practices.
