好記性不如爛筆頭。總也記不住

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
       <el-form-item label="新密碼" prop="newPwd">
        <el-input v-model="ruleForm.newPwd" clearable size="small" type="password"></el-input>
       </el-form-item>
       <el-form-item label="確認密碼" 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">確定</el-button>
        <el-button @click="resetForm('ruleForm')" class="button">重置</el-button>
       </el-form-item>
</el-form>

驗證兩次密碼是否一致 卻保證輸入的密碼在6-16個字元之間

關鍵程式碼如下：

  data() {
   var validatePass = (rule,value,callback) => {
    if (value === '') {
        callback(new Error('請輸入密碼'));
    } else {
     if (this.ruleForm.confirmPwd !== '') {
       this.$refs.ruleForm.validateField('confirmPwd');
     }
     callback();
    }
   };
   var validatePass2 = (rule,callback) => {
     if (value === '') {
       callback(new Error('請再次輸入密碼'));
     } else if (value !== this.ruleForm.newPwd) {
       callback(new Error('兩次輸入密碼不一致!'));
     } else {
       callback();
     }
   };
   return {
    changePwdDialog:false,//修改密碼彈框
    ruleForm: {
     newPwd: '',confirmPwd:''
    },rules: {
     newPwd: [
      { required: true,message: '請輸入密碼',trigger: 'blur' },{ min: 6,max: 16,message: '長度在 6 到 16 個字元',{ validator: validatePass,trigger: 'blur' }
     ],confirmPwd:[
      { required: true,message: '請確認密碼',{ validator: validatePass2,trigger: 'blur',required: true }
     ],}
   }
  },
