Vue.js - Using parent data in component
Option 1
Use this.$parent.limitByNumber
from child component. So your Component template would be like this
<template>
<div class="Post" v-for="post in list | limitBy this.$parent.limitByNumber" />
</template>
Option 2
If you want to use props, you can also achieve what you want. Like this.
Parent
<template>
<post :limit="limitByNumber" />
</template>
<script>
export default {
data () {
return {
limitByNumber: 4
}
}
}
</script>
Child Pots
<template>
<div class="Post" v-for="post in list | limitBy limit">
<!-- Blog Post -->
....
</div>
</template>
<script>
export default {
props: ['list', 'limit'],
created() {
this.list = JSON.parse(this.list);
}
}
</script>
If you want to access some specific parent, you can name all components like this:
export default {
name: 'LayoutDefault'
And then add some function (maybe like vue.prototype or Mixin if you need it in all your components). Something like this should do it:
getParent(name) {
let p = this.$parent;
while(typeof p !== 'undefined') {
if (p.$options.name == name) {
return p;
} else {
p = p.$parent;
}
}
return false;
}
and usage could be like this:
this.getParent('LayoutDefault').myVariableOrMethod
