el-form的必填项

根据提供的引用内容可以得出以下结论：

引用中的代码展示了一个el-form的表单结构，其中的必填项通过rules属性进行验证。具体来说，fIncomeWay和fOppositeBank是必填项，分别对应的规则为：

fIncomeWay的规则为：[{ required: true, message: "请选择来款方式", trigger: ["blur", "change"] }]

fOppositeBank的规则为：[{ required: true, message: "请输入来款银行", trigger: "blur" }]

引用中的代码展示了另一个el-form的表单结构，其中的mobilePhone和email是必填项，分别对应的规则为：

mobilePhone的规则为：[{ required: true, message: '请输入手机号码', trigger: 'blur' }, { validator: checkMobile, max: 11, message: '请输入正确的格式', trigger: 'blur' }]

email的规则为：[{ required: true, message: '请输入电子邮箱', trigger: 'blur' }, { validator: checkEmail, max: 11, message: '请输入正确的格式', trigger: 'blur' }]

根据引用中的介绍，el-form的必填项可以通过设置相应的rules属性中的required为true来实现。以上就是el-form的必填项的相关信息。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
