自定义事件内容分发

这个听的云里雾里，下面是一个示例demo

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div id="app">
    <todo>
        <todo-title slot="todo-title" v-bind:title="title1"></todo-title>
        <todo-nie slot="todo-nie" v-for="(item,index) in items" v-bind:item="item" v-bind:index="index"
                  v-on:remove="removeitem(index)"></todo-nie>
    </todo>
</div>
<!--导入Vue.js-->
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.21/dist/vue.min.js"></script>
<script>
    Vue.component("todo",
        {
            template: '<div>\<slot name="todo-title"></slot>\<ul>\<slot name="todo-nie"></slot>\</ul>\</div>'
        })
    Vue.component("todo-title",
        {
            props: ['title'],
            template: '<div>{{title}}</div>'
        })
    Vue.component("todo-nie",
        {
            props: ['item', 'index'],
            template: '<li>{{index}}---{{item}}<button @click="remove">删除</button></li>',
            methods: {
                remove: function (index) {
                    this.$emit('remove', index)
                }
            }
        })
    // 创建一个新的 Vue 实例
    var vm = new Vue({
        el: '#app',
        data: {
            items: ['带土', '爱', '琳'],
            title1: '标题'
        },
        methods: {
            removeitem: function (index) {
                console.log("删除了" + this.items[index] + "ok")
                this.items.splice(index, 1);//删除一个元素
            }
        }
    });

</script>
</body>
</html>
