vue 之radio绑定v-model

示例：

单选radio

<label ><input type="radio" value="0" v-model="branch">debug</label>

<label > <input type="radio" value="1" v-model="branch">release</label>

容易出错的

例子：绑定了两个model

<label ><input type="radio" name="name1" value="0" v-model="branch">debug</label>

<label > <input type="radio" name="name1" value="1" v-model="branch1">release</label>
