Javascript code:
var main = new Vue({
el: "#main",
data: {
currentView: "top",
},
});
var topComponent = Vue.component('top', Vue.extend({
template: "#top",
}));
Now when I access main.currentView, I get "top". But with this string 'top', how do i get the component topComponent
?
From the VueJS guide
Despite the existence of props and events, sometimes you might still need to directly access a child component in JavaScript. To achieve this you have to assign a reference ID to the child component using
ref
. For example:
var parent = new Vue({ el: '#parent' }) // access child component instance var child = parent.$refs.profile
<div id="parent"> <user-profile ref="profile"></user-profile> </div>
It's easy. You can access the topComponent
just using Vue.component
.
var topComponent = Vue.component('top');
Now you have topComponent
, you can do a lot of things with its methods.
cid
options
super
extend
directive
filter
partial
transition
component

It uses the v-view directive in the html, which takes a string to change the viewmodel displayed. Some sweet transitions going on as well.
