vue3中自定义校验函数密码不生效问题

由于在自定义的校验规则中只校验了有数据的情况，以至于在没输入时，校验不生效

（1）用户不输入校验不生效

const validateSurePassword = (rule, value, callback) => {if (value !== '') {if (value.length < 8) {callback(new Error('请输入至少8位确认密码'))return false} else if (value !== formState.newPassword) {callback(new Error('两次输入的新密码不一致'))return false} else {callback()}}
}
const validatePassword = (rule, value, callback) => {// const reg = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*])(?!.*\s).{8,}$/if (value !== '') {if (value.length < 8) {callback(new Error('请输入至少8位的密码'))return false} else if (!/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*])(?!.*\s).{8,}$/.test(value)) {callback(new Error('密码必须包含大小字母、数字和特殊字符(@!*#$%&_=)'))return false} else {callback()}}
}

（2）改进上述自定义校验

const validateSurePassword = (rule, value, callback) => {if (value !== '') {if (value.length < 8) {callback(new Error('请输入至少8位确认密码'))return false} else if (value !== formState.newPassword) {callback(new Error('两次输入的新密码不一致'))return false} else {callback()}} else {callback(new Error('请输入确认密码'))return false}
}
const validatePassword = (rule, value, callback) => {// const reg = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*])(?!.*\s).{8,}$/if (value !== '') {if (value.length < 8) {callback(new Error('请输入至少8位的密码'))return false} else if (!/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*])(?!.*\s).{8,}$/.test(value)) {callback(new Error('密码必须包含大小字母、数字和特殊字符(@!*#$%&_=)'))return false} else {callback()}} else {callback(new Error('请输入新密码'))return false}
}

（3）修改密码弹窗示例
