<template>
<van-form>
<van-field
v-model="name"
label="姓名"
placeholder="请输入姓名"
/>
<van-field
v-model="gender"
label="性别"
placeholder="请选择性别"
readonly
clickable
@click="showGenderPicker = true"
/>
<van-field
v-model="age"
label="年龄"
placeholder="请输入年龄"
type="number"
/>
<van-field
v-model="email"
label="邮箱"
placeholder="请输入邮箱"
type="email"
/>
<van-field
v-model="phone"
label="手机号码"
placeholder="请输入手机号码"
type="tel"
/>
</van-form>
<van-picker
v-model="gender"
title="选择性别"
:columns="genderOptions"
:show-toolbar="true"
:visible-item-count="5"
@confirm="showGenderPicker = false"
@cancel="showGenderPicker = false"
/>
</template>

<script>
export default {

}
</script>
