1.使用update更改内容时，输入字段的过程中点回车，删除，空格等键都会导致自动退出编辑模式，有什么好办法可以解决这个问题吗？2.还有就是使用delete删除的时候，如果下一行有内容展开，会自动收起，这又得如何解决？具体代码如下：<!DOCTYPE html><html><head> <meta charset="UTF-8"> <title>树形视图扩展</title> <style> body { font-family: Menlo, Consolas, monospace; color: #444; } .item { cursor: pointer; } .bold { font-weight: bold; } ul { padding-left: 1em; line-height: 1.5em; list-style-type: dot; } </style> <script src="https://cdn.bootcss.com/vue/2.4.2/vue.min.js"></script></head><body><script type="text/x-template" id="item-template"> <li> <div :class="{bold: isFolder}" @click="toggle" @dblclick="changeType"> <span v-if="up">{{ model.name }}</span> <input v-else type="text" v-model="model.name" @click.stop> <span v-if="isFolder">[{{ open ? '-' : '+' }}]</span> <span class="bold" @click.stop="$emit('del', index)">[del]</span> <span class="bold" @click.stop="upd">[update]</span> </div> <ul v-if="isFolder" v-show="open"> <item class="item" v-for="(item, index) in model.children" :key="index + item.name" :index="index" :model="item" @del="model.children.splice($event, 1)"></item> <li class="add" @click="addChild">+</li> </ul> </li></script><p>树形结构</p><ul id="demo"> <item class="item" v-for="(model, index) in treeData" :key="index + model.name" :index="index" :model="model" @del="treeData.splice($event, 1)"></item></ul><script> var data = [ {name: 'han'}, {name: 'wang'}, { name: 'liu', children: [ {name: 'zhang'}, {name: 'lu'} ] } ]; Vue.component('item', { template: '#item-template', props: { model: Object, index: Number },
