Vue2-filter-list
Prebuilt filters for Vue.js
Table of contents:
Get Started
NPM
npm install vue2-filter-list
When used with a module system, you must explicitly install the filters via Vue.use()
:
import Vue from 'vue'
import VueFilterList from 'vue2-filter-list'
Vue.use(VueFilterList)
You don't need to do this when using global script tags.
To use one of the predefined methods (such as limitBy
, filterBy
, find
, or orderBy
) in your component, you also need to add Vue2Filters.mixin
to mixin list:
import VueFilterList from 'vue2-filter-list'
export default {
...
mixins: [VueFilterList.mixin],
...
}
Collection
after

{ name: 'zap' },
]
<tr v-for="col in after(collection,2)">
{{ col.name }}
</tr>
<!--result:
baz
zap
-->
