1.密码校验规则

格应包含大小写字母、数字和特殊符号,长度为8-20

 var validateRetrievePassword = (rule, value, callback) => {
            let reg =
                /^(?=.*[A-Za-z])(?=.*\d)(?=.*[`~!@#$%^&*()_+<>?:"{},.\/\\;'[\]])[A-Za-z\d`~!@#$%^&*()_+<>?:"{},.\/\\;'[\]]{8,20}$/;
            if (!value) {
                callback(new Error('密码不能为空'));
            } else if (!reg.test(value)) {
                callback(new Error('格应包含大小写字母、数字和特殊符号,长度为8-20'));
            } else {
                callback();
            }
        };

2.确认密码校验规则

俩次密码一致

var validateNewPasswordSecond = (rule, value, callback) => {
        var reg =
          /^(?=.*[A-Za-z])(?=.*\d)(?=.*[`~!@#$%^&*()_+<>?:"{},.\/\\;'[\]])[A-Za-z\d`~!@#$%^&*()_+<>?:"{},.\/\\;'[\]]{8,20}$/;
        if (!value) {

        } else if (value !== this.param.password) {
          // console.log(value,this.param.password,'value')
          callback(new Error('两次输入密码不一致!'));
        } else if (!reg.test(value)) {
          callback(new Error('格式应包含大小写字母、数字和特殊符号,长度为8-20'));
        } else {
          callback();
        }

3.html代码页面

​
 <el-form-item prop="password">
            <i class="required">*</i>
            <el-input :show-password="true" type="password" v-model="param.password" placeholder="请输入密码"   auto-complete="new-password">
            </el-input>
          </el-form-item>
          <el-form-item prop="confirmPassword">
            <i class="required">*</i>
            <el-input :show-password="true" type="password" v-model="param.confirmPassword" placeholder="请确认密码"   auto-complete="new-password">
            </el-input>
          </el-form-item>

4.验证rules

         rules: {    
       
          password: [{
					   required: true,
             validator:validateRetrievePassword,
				  }],

          confirmPassword:  [{
					   required: true,
					   validator: validateNewPasswordSecond,
					
				}],
       
        },
