官方示例
1、只对于数据层面来说。不涉及html和css。
2、通过Vue.component方法声明。
var EmptyList = { /* ... */ }
var TableList = { /* ... */ }
var OrderedList = { /* ... */ }
var UnorderedList = { /* ... */ }
Vue.component('smart-list', {
functional: true,
props: {
items: {
type: Array,
required: true
},
isOrdered: Boolean
},
render: function (createElement, context) {
function appropriateListComponent () {
var items = context.props.items
if (items.length === 0) return EmptyList
if (typeof items[0] === 'object') return TableList
if (context.props.isOrdered) return OrderedList
return UnorderedList
}
return createElement(
appropriateListComponent(),
context.data,
context.children
)
}
})
