1.使用 el-form 组件
el-form 是一个表单容器，可以包含多个 el-form-item，每个 el-form-item 包裹具体的表单控件，如输入框、选择器、日期选择器等。

<template><el-form :model="form" label-width="120px"><el-form-item label="用户名"><el-input v-model="form.username"></el-input></el-form-item><el-form-item label="密码"><el-input v-model="form.password" type="password"></el-input></el-form-item><el-checkbox-group v-model="checkList"><el-checkbox label="Option A" value="Value A" /><el-checkbox label="Option B" value="Value B" /><el-checkbox label="Option C" value="Value C" /><el-checkbox label="disabled" value="Value disabled" disabled /><el-checkboxlabel="selected and disabled"value="Value selected and disabled"disabled/></el-checkbox-group><div class="example-basic"><el-time-picker v-model="value1" placeholder="Arbitrary time" /><el-time-pickerv-model="value2"arrow-controlplaceholder="Arbitrary time"/></div><el-form-item><el-button type="primary" @click="submitForm">提交</el-button></el-form-item></el-form>
</template><script setup>
import { ref } from 'vue';
const checkList = ref(['Value selected and disabled', 'Value A'])
const form = ref({username: '',password: ''
});const submitForm = () => {console.log('提交表单数据:', form.value);console.log('多选',checkList.value,value1,value2);
};
const value1 = ref()
const value2 = ref()
</script><style>
.example-basic .el-date-editor {margin: 8px;
}
</style>
