vue.js使用v-model指令实现的数据双向绑定功能示例

本文实例讲述了vue.js使用v-model指令实现的数据双向绑定功能。分享给大家供大家参考，具体如下：

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：</p> <p>app.html</p> <pre class="brush:js;"> <!doctype html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <title> vuejs v-model 数据双向绑定 </title> <sty1e type="text/css"> [v-cloak] { display: none } </style> </head> <body> <p><pre class='brush:php;toolbar:false'>data: {{$data | json 2}}</pre></p> </body> </html> </pre> <p>使用本站<strong>在线HTML/CSS/Javascript代码运行工具</strong>http://tools.jb51.net/code/HtmlJsRun测试运行效果如下：</p> <p></p> <p>希望本文所述对大家vue.js程序设计有所帮助。</p></div> </div> <div
