vue Example Method for Verifying the Consistency of Passwords Entered Twice

The palest ink is better than the best memory. I can't always remember

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
       <el-form-item label=" New password " prop="newPwd">
        <el-input v-model="ruleForm.newPwd" clearable size="small" type="password"></el-input>
       </el-form-item>
       <el-form-item label=" Confirm password " 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"> Determine </el-button>
        <el-button @click="resetForm('ruleForm')" class="button"> Reset </el-button>
       </el-form-item>
</el-form>

Verify that the password is 1 twice to ensure that the password entered is between 6 and 16 characters

The key code is as follows:

  data() {
   var validatePass = (rule, value, callback) => {
    if (value === '') {
        callback(new Error(' Please enter your password '));
    } else {
     if (this.ruleForm.confirmPwd !== '') {
       this.$refs.ruleForm.validateField('confirmPwd');
     }
     callback();
    }
   };
   var validatePass2 = (rule, value, callback) => {
     if (value === '') {
       callback(new Error(' Please enter your password again '));
     } else if (value !== this.ruleForm.newPwd) {
       callback(new Error(' Enter the password twice. No 1 To !'));
     } else {
       callback();
     }
   };
   return {
    changePwdDialog:false,// Modify the password bullet box 
    ruleForm: {
     newPwd: '',
     confirmPwd:''
    },
    rules: {
     newPwd: [
      { required: true, message: ' Please enter your password ', trigger: 'blur' },
      { min: 6, max: 16, message: ' The length is in  6  To  16  Characters ', trigger: 'blur' },
      { validator: validatePass, trigger: 'blur' }
     ],
     confirmPwd:[
      { required: true, message: ' Please confirm the password ', trigger: 'blur' },
      { min: 6, max: 16, message: ' The length is in  6  To  16  Characters ', trigger: 'blur' },
      { validator: validatePass2, trigger: 'blur', required: true }
     ],
    }
   }
  },
