(尚012)Vue表单数据的自动手集(表单数据提交,需要收集表单数据)

 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

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div id="demo">
    <!--.prevent阻止默认行为-->
    <form action="/xxx" @submit.prevent="handleSubmit">
        <span>用户名:</span>
        <input type="text" v-model="username"><br>

        <span>密码:</span>
        <input type="password" v-model="pwd"><br>

        <span>性别:</span>
        <!--value="女"希望女被选中-->
        <input type="radio" id="female" value="女" v-model="sex">
        <label for="female">女</label>
        <input type="radio" id="male" value="男" v-model="sex">
        <label for="male">男</label><br>

        <span>爱好:</span>
        <input type="checkbox" id="basket" value="basket" v-model="likes">
        <label for="basket">篮球</label>
        <input type="checkbox" id="football" value="foot" v-model="likes">
        <label for="football">足球</label>
        <input type="checkbox" id="golf" value="golf" v-model="likes">
        <label for="golf">高尔夫</label>
        <input type="checkbox" id="vollay" value="vollay" v-model="likes">
        <label for="vollate">排球</label><br>

        <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
