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: {{$data | json 2}}</pre></p><br></div><br></body></p> </div> </div> <div class="clear"></div> </div> <div class="wdhdnr"> <div class="huidanrtop"> <div class="wdhuidaxinx"> <div class="wdhuidaxm">网友（2）：</div> </div> </div> <div class="clear"></div> <div class="wdhuidanrmid"> <div class="zuijiacont"> <p><pre t="code" l="js">//html 代码<br><input v-model="message" placeholder="edit me"><br><p>Message is: {{ message }}</p></pre> <pre t="code" l="js">// vue代码<br>var vm = new Vue({<br> 宴磨团 el:"#app",<br> data: {<br> message: '绑定多行文本'<br> 晌橘 }<br> })</pre> <p>这样 你就完成v-model的双向游灶绑定了。你修改input的值，data.message的值也会跟着改变。</p></p> </div> </div> <div class="clear"></div> </div> </div> </div> <div class="wendaright"> <div class="wdluluerwema"> <div class="wdxgwttop">相关问答</div> <div class="wdxgwtnr"> </div> <div class="clear"></div> </div> <!-- 其他随机问答['id'=>alphaID($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://czqahb.com/article/468002661.html">我的CPU是酷睿T2250,1.73主频，双核，内存2G，显卡是ATI X2300，请问我该装什么系统？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/182614147.html">内存超频时序问题</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/502980965236988204.html">见面怎么和同事打招呼才不显得尴尬？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/1308754106589664819.html">新福克斯和科鲁兹哪个好一点啊</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/104331701.html">鼻炎片能长期吃吗?</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/433618173.html">Premiere 能更换什么颜色视频背景 ，白色行吗？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/1885894775464275988.html">高一新生开学后怎样才能快速进入学习状态，有什么好的学习方法呢？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/1893833658846996460.html">国际商务硕士 就业前景到底怎样？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/177288558436951684.html">张杰和周杰伦谁更有名？谁的歌好听？？？？</a></div> </div> <div class="wdxgwtcont"> <div class="wdxgtitle"><a href="https://czqahb.com/article/123374127.html">买了貌似是翻新的PSP2000</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://czqahb.com/static/old/img/fhtop.png" 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?0c9f72217b0fd07e33b2b148bdd4490c"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script> </body> </html>
