1.使用vuejs 官网上面的例子,在控制台中发现了错误了,
VM2369 vue.js:2658 [Vue warn]: Unknown custom element: <todo-item> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
(found in root instance)
2.源码:
<div id="app-7"> <ol> <!-- Now we provide each todo-item with the todo object --> <!-- it's representing, so that its content can be dynamic --> <todo-item v-for="item in groceryList" v-bind:todo="item"></todo-item> </ol></div>
Vue.component('todo-item', { props: ['todo'], template: '<li>{{ todo.text }}</li>'})var app7 = new Vue({ el: '#app-7', data: { groceryList: [ { text: 'Vegetables' }, { text: 'Cheese' }, { text: 'Whatever else humans are supposed to eat' } ] } })
