自动收集,就是我一输入数据,就自动收集,等我点击提交按钮的时候,数据就收集好了
1.使用v-model对表单数据自动收集
1)text/textare----单行/多行输入框
2)checkbox----多选
3)radio----单选
4)select----下拉框

<span>城市:</span>
<select v-model="cityId">
<option value="">未选择</option>
<!--最终提交过去的是id,所以value="city.id",因为city.id是文本,故写成:value-->
<option :value="city.id" v-for="(city,index) in allCitys" :key="index">{{city.name}}</option>
</select><br>
<span>介绍:</span>
<textarea rows="10" v-model="description"></textarea><br><br>
<input type="submit" value="注册">
</form>
</div>
<script type="text/javascript" src="../js/vue.js"></script>
<script type="text/javascript">
new Vue({
el:'#demo',
data:{
username: '',
pwd:'',
//女是跟value的值匹配
sex:'女',
//多选应该是数组
likes:['foot'],
allCitys: [{id:1,name:'BJ'},{id:2,name:'SH'},{id:3,name:'GD'}],
cityId: '3',
description:''
},
methods:{
handleSubmit(){
console.log(this.username,this.pwd,this.sex,this.likes,this.cityId,this.description)
}
}
})
</script>
</body>
</html>
4.点击submit可以通过console控制台看到提交的数据;也可以通过vue来查看
