3.账号和密码输入并验证
(1)创建state存储双向绑定输入框内容及单选框选择
（2）表单验证
代码如下
<template>
<div class="input">
<el-form :model="state.loginParam" :rules="rules" ref="form" label-width="50px" style="width: 350px">
<el-form-item label="账号" prop="phone">
<el-input placeholder="请输入11位手机号" v-model="state.loginParam.phone"></el-input>
</el-form-item>
<el-form-item label="密码" prop="code">
<el-input placeholder="请输入6位密码" v-model="state.loginParam.code"/>
</el-form-item>
<el-form-item>
<el-checkbox label="记住账号" v-model="state.saveUser"></el-checkbox>
</el-form-item>
</el-form>
</div>
</template><script setup lang="ts">
import { reactive, ref } from "vue";
import useUserStore from "../../store/modules/user";
let userStore = useUserStore();
const state = reactive({
loginParam: {
phone: '',
code: '',
},
saveUser: false
});
// 自定义校验规则：手机号码自定义校验规则
const validatorPhone = (rule: any, value: any, callBack: any) => {
// rule 表单校验的规则对象 value：当前文本的内容 callback：回调函数
const reg =
/^1((34[0-8])|(8\d{2})|(([35][0-35-9]|4[579]|66|7[35678]|9[1389])\d{1}))\d{7}$/;
if (reg.test(value)) {
callBack();
} else {
callBack(new Error("请输入正确的手机号格式"));
}
};
// 自定义校验规则：验证码自定义校验规则
const validatorCode = (rule: any, value: any, callBack: any) => {
// rule 表单校验的规则对象 value：当前文本的内容 callback：回调函数
if (/^\d{6}$/.test(value)) {
callBack();
} else {
callBack(new Error("请输入正确的密码格式"));
}
};
// 获取form组件实例
let form = ref<any>();
const rules = {
phone: [{ trigger: "change", validator: validatorPhone }],
code: [{ trigger: "change", validator: validatorCode }],
};
</script>效果如下：
4. 点击登录按钮
本地存储：
登录数据呈现：
若数据仓库中phone数据为空，显示“登录/注册”，若有phone数据，则显示
