vue 验证两次输入的密码是否一致的方法示例

好记性不如烂笔头。总也记不住

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
       <el-form-item label="新密码" prop="newPwd">
        <el-input v-model="ruleForm.newPwd" clearable size="small" type="password"></el-input>
       </el-form-item>
       <el-form-item label="确认密码" prop="confirmPwd">
        <el-input v-model="ruleForm.confirmPwd" clearable size="small" type="password"></el-input>
       </el-form-item>
       <el-form-item>
        <el-button type="primary" @click="submitForm('ruleForm')" class="button">确定</el-button>
        <el-button @click="resetForm('ruleForm')" class="button">重置</el-button>
       </el-form-item>
</el-form>

验证两次密码是否一致 却保证输入的密码在6-16个字符之间

关键代码如下:

  data() {
   var validatePass = (rule, value, callback) => {
    if (value =http://www.cppcns.com/wangluo/javascript/=='') {
        callback(new Error('请输入密码'));
    } else {
     if (this.ruleForm.confirmPwd !== '') {
       this.$refs.ruleForm.validateField('confirmPwd');
     }
     callback();
    }
   };
   var validatePass2 = (rule, value, callback) => {
     if (value =http://www.cppcns.com/wangluo/javascript/=='') {
       callback(new Error('请再次输入密码'));
     } else if (value !== this.ruleForm.newPwd) {
       callback(new Error('两次输入密码不一致!'));
     } else {
       callback();
     }
   };
   return {
    changePwdDialog:false,//修改密码弹框
    ruleForm: {
     newPwd: '',
     confirmPwd:''
    },
    rules: {
     newPwd: [
      { required: true, message: '请输入密码', trigger: 'blur' },
      { min: 6, max: 16, message: '长度在 6 到 16 个字符', trigger: 'blur' },
      { validator: validatePass, trigger: 'blur' }
     ],
     confirmPwd:[
      { required: true, message: '请确认密码', trigger: 'blur' },
      { min: 6, max: 16, message: '长度在 6 到 16 个字符', trigger: 'blur' },
      { validator: validatePass2, trigger: 'blur', required: true }
     ],
    }
   }
  },
