vue+elementUI用户修改密码的前端验证

用户登录后修改密码，密码需要一定的验证规则。旧密码后端验证是否正确；前端验证新密码的规范性，新密码规范为：6-16位，至少含数字/字母/特殊字符中的两种；确认密码只需要验证与新密码是否一致；

弹窗结构

<el-dialog title="修改密码":visible.sync="passDlgVisible"@close="passDlgClose"width="400px"><el-form :model="passForm"ref="passRef":rules="passRules"hide-required-asterisklabel-width="70px"size="small"><el-form-item label="旧密码" prop="oldPassword"><el-input v-model="passForm.oldPassword" show-password></el-input></el-form-item><el-form-item label="新密码" prop="newPassword"><el-input v-model="passForm.newPassword" show-password></el-input></el-form-item><el-form-item label="确认密码" prop="confirmPassword"><el-input v-model="passForm.confirmPassword" show-password></el-input></el-form-item></el-form><span slot="footer"><el-button @click="passDlgVisible=false" size="small">取消</el-button><el-button @click="passSave" type="primary" size="small">确认</el-button></span>
</el-dialog>

form验证规则

passRules: {oldPassword:[{required: true, message: '请输入旧密码', trigger: 'blur'}],newPassword:[{validator: this.validNewPass, trigger: 'blur'}],confirmPassword:[{validator: this.validConfirmPass, trigger: 'blur'}]
}

验证函数

/*** 验证新密码*/
validNewPass(rule, value, callback) {let reg = /(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]{6,16}$/if (value === '') {callback(new Error('请输入新密码'));} else if (!reg.test(value)) {callback(new Error('6-16位，至少含数字/字母/特殊字符中的两种'))} else {if (this.passForm.confirmPassword !== '') {this.$refs.passRef.validateField('confirmPassword');}callback();}
},/*** 验证确认密码*/
validConfirmPass(rule, value, callback) {if (value === '') {callback(new Error('请再次输入密码'));} else if (value !== this.passForm.newPassword) {callback(new Error('两次输入密码不一致!'));} else {callback();}
}

弹窗关闭后清空字段和验证

/*** 弹窗关闭事件*/
passDlgClose() {this.passForm = {oldPassword: '',newPassword: '',confirmPassword: ''}this.$refs.passRef.clearValidate();
}

提交表单

passSave() {this.$refs.passRef.validate((valid) => {if (valid) {this.passForm.userName = this.userNameapi.user.editPass(this.passForm).then(res => {this.passDlgVisible = false;})} else {return false;}});
}
