Vue component form data echo validation and submit code

Recently, the project needs to develop a single page in vue, so I will study how to use vue components to echo, verify and submit form data.

code show as below:

<template>
    <div class="index">
        <!--header-bar></header-bar-->
        <div style="margin:20px;">
            <div class="item">
                <p>住户名称:</p>
                <p>
                    <input type="text" value="username" v-model="formStatus.username" placeholder="输入名称">
                </p>
            </div>
            <div class="item">
                <p>住户类型:</p>
                <p>
                    <label v-for="(item, index) in zhuhuType">
                        <span>{{item.name}}</span>
                        <input type="radio" name = "zhuhutype" :value="item.id" :checked="item.isChecked" @click="changeZh(index)" v-model="formStatus.zhuhuType">
                    </label>
                </p>
            </div>
            <div class="item">
                <p>设备名称:</p>
                <p>
                    <label v-for="(item, index) in shebeiType">
                        <span>{{item.name}}</span>
                        <input type="checkbox" :value="item.id" :checked="item.isChecked" @click="changeSb(index)" v-model="formStatus.shebeiType">
                    </label>
                </p>
            </div>
            <div class="item">
                <p>住户大小:</p>
                <p>
                    <select v-model="formStatus.zhuhudaxiao">
                        <option value="0">请选择</option>
                        <option v-for="option in zhuhudaxiao" v-model="zhuhudaxiao" :id = "option.id" :value="option.value" >{{option.name}}</option>
                    </select>
                </p>
            </div>
            <div class="item">
                <p>住户留言:</p>

                </p>
            </div>

        </div>
        <p style="margin:20px 0;"><button @click="save">点击保存</button></p>
    </div>
