以下为表单控件的实践,代码敬上,直接新建html文件,粘贴复制即可看到效果
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>PlayAround2 Have Fun</title> <script src="https://cdn.jsdelivr.net/vue/1.0.26/vue.min.js"></script> <style> h2{ text-decoration:underline; } .red{ color: red; } .green{ color: green; } </style> </head> <body> <div id="app"> <h2>checkBox</h2> <input type="checkbox" v-model="checked"> <label>{{checked}}</label> <h2>multi checkbox</h2> <input type="checkbox" id="Kobe" value="Kobe" v-model="names"> <label for="Kobe">Kobe</label> <input type="checkbox" id="Curry" value="Curry" v-model="names"> <label for="Curry">Curry</label> <input type="checkbox" id="Aaron" value="Aaron" v-model="names"> <label for="Aaron">Aaron</label> <br> <span>Checked names: {{names | json}}</span> <h2>Radio</h2> <input type="radio" id="one" value="one" v-model="picked"> <label for="one">one</label> <br> <input type="radio" id="two" value="two" v-model="picked"> <label for="two">two</label> <br> <span>Picked: {{picked}}</span> <h2>Select</h2> <select v-model="selected"> <option selected>Kobe</option> <option>Curry</option> <option>Aaron</option> </select> <span>Selected: {{selected}}</span> <h2>Multi Select</h2> <select multiple v-model="multiSelected"> <option>Kobe</option> <option>Curry</option> <option>Aaron</option> </select> <span>Selected: {{multiSelected}}</span> <h2>Select with for</h2> <select v-model="selectedPlayer"> <option v-for="option in options" :value="option.value">{{option.text}}</option> </select> <span>Selected: {{selectedPlayer}}</span> <h2>Lazy-改变更新的事件从input->change</h2> <input v-model="msg" lazy> <span>Msg:{{msg}}</span> <h2>Number(没啥吊用。。.2->0.2,仅此而已吗?)</h2> <input v-model="age" number> <span>age:{{age}}</span> <h2>debounce-延迟更新view</h2> <p>Edit me<input v-model="delayMsg" debounce="500"></p> <span>delayMsg:{{delayMsg}}</span> </div> <script> var vm = new Vue({ el:"#app", data:{ checked:false, names:[], picked:"", selected:"", multiSelected:"", options:[ {text:"Kobe",value:"Bryant"}, {text:"Stephen",value:"Curry"}, {text:"Aaron",value:"Kong"} ], selectedPlayer:"", msg:"", age:"", delayMsg:"" }, methods:{ } }) </script> </body> </html>
使用vue的几个优点:
1、只需关注model层的数据处理,无需处理复杂的view层更新,vue会在model改变时自动对view层进行更新;
2、vue提供一系列的小工具帮助开发者处理数据绑定中得问题,比如computed可以提供计算的扩展,还有过滤器、排序等支持;
3、代码简洁,分层清晰。html里进行数据绑定,js里只需处理数据以及后台交互;
4、提供自定义组件功能,进一步规范前端架构。目前暂时没有使用,后续研究研究。
