vue.js的一大功能便是实现数据的双向绑定，本文就表单处理时运用v-model指令实现双向绑定做一个介衫渣绍：v-model这个指令只能用在, ,这些表单元素上，所谓双向绑定，指的就是我们在js中的vue实例中的data与其渲染的dom元素上的内容保持一致，两者无论谁被改变，另一方也会相应的更新为相同的数据。这是通过设置属性访问器实现的。例如：<br><br>app.html<br><!doctype html><br><html lang="zh-CN"><br><早此head><br><meta charset="UTF-8"><br><title><br>vuejs 过滤器、ajax数据、嵌套循环、if判断、事件监听<br></title><br><style type="text/css"><br>[v-cloak] { display: none }<br></style><br></head><br><br><body><br><div id="app"><br><form><br>姓名：<br><input type="text" v-model="或睁悄data.name" placeholder="姓名"/><br><br /><br>性别：<br><input type="radio" id="one" value="One" v-model="data.sex"/><br><label for="man">男</label><br><input type="radio" id="two" value="Two" v-model="data.sex"/><br><label for="male">女</label><br><br /><br><input type="checkbox" id="jack" value="book" v-model="data.interest"/><br><label for="jack">阅读</label><br><input type="checkbox" id="john" value="swim" v-model="data.interest"/><br><label for="john">游泳</label><br><input type="checkbox" id="move" value="game" v-model="data.interest"/><br><label for="move">游戏</label><br><input type="checkbox" id="mike" value="song" v-model="data.interest"/><br><label for="mike">唱歌</label><br><br /><br>身份：<br><select v-model="data.identity"><br><option value="teacher" selected>教师</option><br><option value="doctor">医生</option><br><option value="lawyer">律师</option><br></select> <br></form><br><p><pre>data: {{$data | json 2}}</pre></p><br></div><br></body></p> </div> </div> <div class="clear"></div> </div> <div class="wdhdnr"> <div class="huidanrtop"> <div class="wdhuidaxinx"> <div class="wdhuidaxm">回答（2）：</div> </div> </div> <div class="clear"></div> <div class="wdhuidanrmid"> <div class="zuijiacont"> <p><pre t="code" l="js">//html 代码<br><input v-model="message" placeholder="edit me"><br><p>Message is: {{ message }}</p></pre> <pre t="code" l="js">// vue代码<br>var vm = new Vue({<br> 宴磨团 el:"#app",<br> data: {<br> message: '绑定多行文本'<br> 晌橘 }<br> })</pre> <p>这样 你就完成v-model的双向游灶绑定了。你修改input的值，data.message的值也会跟着改变。</p></p> </div> </div> <div class="clear"></div> </div> </div> </div> <div class="wendaright"> <div class="wdluluerwema"> <div class="wdxgwttop">相关问答</div> <div class="wdxgwtnr"> </div> <div class="clear"></div> </div> <!-- 其他随机问答['id'=>alphaID($like['zid'])] --> <div class="wdluluerwema"> <div class="wdxgwttop">最新问答</div> <div class="wdxgwtnr"> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/137669829.html">小沈阳小品《疯狂粉丝团》的台词？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/29788207.html">英语作文:介绍一下中国的餐桌礼仪</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/76570950.html">关于队列比赛的作文</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/334232975.html">培养皿接种后为什么要倒置培养</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/590423086141139285.html">我国中国境内税务局的主要工作职责主要有哪些？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/391067431.html">“两票三制”指的是什么?</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/1303880236845168579.html">40-38+36+34+...+8-6+4-2脱式简便计算</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/517495937.html">中国现役军用望远镜是什么型号</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/137939209449703005.html">求助一首英文歌!</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://58z.net/z/458799433252584125.html">三星i9300手机root后怎样卸载自带应用程序</a></div> </div> </div> </div> </div> <div class="clear"></div> <div class="footer"> <!-- 移动底部导航 --> <div class="fanhuitop"><a href="#top" ref="nofollow"><img src="https://58z.net/static/old/img/fhtop.png" alt="返回顶部" title="返回顶部"></a></div> <div class="dibu"> <div class="dibu"> </div> </div> <div class="banquan"> <p>内容全部来源于网络收集，如有侵权，请联系网站删除：QQ：24596024</p> </div> </div> </div> </div> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "https://hm.baidu.com/hm.js?bc215519b6d2b72984cdb0a467b5dcf6"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script> </body> </html>
