How to render a list of static content with Vue named slot?
This is easily accomplished with a render function.
Vue.component("comp", {
render(h){
let links = this.$slots.links.map(l => h('li', {class: "comp-item"}, [l]))
return h('ul', {class: 'comp'}, links)
}
})
Here is a working example.
console.clear()
Vue.component("comp", {
render(h){
let links = this.$slots.links.map(l => h('li', {class: "comp-item"}, [l]))
return h('ul', {class: 'comp'}, links)
}
})
new Vue({
el: "#app"
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="app">
<comp>
<a href="#" slot="links">link 1</a>
<a href="#" slot="links">link 2</a>
</comp>
</div>
Or with the help of a small utility component for rendering vNodes you could do it like this with a template.
Vue.component("vnode", {
functional: true,
render(h, context){
return context.props.node
}
})
Vue.component("comp", {
template: `
<ul class="comp">
<li class="comp-item" v-for="link in $slots.links"><vnode :node="link" /></li>
</ul>
`
})
new Vue({
el: "#app"
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="app">
<comp>
<a href="#" slot="links">link 1</a>
<a href="#" slot="links">link 2</a>
</comp>
</div>
You can make use of scoped slots instead of slots
Your comp
component receives a prop links
which is an array of links(since static initialized as a custom option). Iterate over the links
and pass link
as data to the slot just like passing props to a component
Vue.component("comp", {
template: `
<ul class="comp">
<li class="comp-item" v-for="link in links">
<slot v-bind="link"></slot>
</li>
</ul>
`,
props: ["links"]
})
new Vue({
el: "#app",
// custom static option , accessed using vm.$options.links
links: [
{text: "link1"},
{text: "link2"},
{text: "lin3"}
]
})
In the parent where the comp
component is used make use of a <template>
element with a special attribute slot-scope
, indicating that it is a template for a scoped slot.
The value of slot-scope
will be used as the name of a temporary variable that holds the props object passed from the child:
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="app">
<comp :links="$options.links">
<template slot-scope="link">
<a href="#">{{link.text}}</a>
</template>
</comp>
</div>
