Vue js vee validate password confirmation always false

问题

I'm trying to use vee validate to verify the password using this code.

<div>
    <input type="password"
           placeholder="Password"
           v-model="password"
           v-validate="'required|min:6|max:35|confirmed'"
           name="password" />
</div>
<div>
    <span>{{ errors.first('password') }}</span>
</div>
<div>
    <input type="password"
           placeholder="Confirm password"
           v-model="confirmPassword"
           v-validate="'required|target:password'"
           name="confirm_password" />
</div>
<div>
    <span>{{ errors.first('confirm_password') }}</span>
</div>

But it always says The password confirmation does not match. What went wrong in my code?

回答1:

Your password input must have ref="password" - that's how vee-validate finds the target:

<input v-validate="'required'" ... ref="password"> (Thanks, Ryley).

confirmed:{target} - Input must have the same value as the target input, specified by {target} as the target field’s name.

Also, there's an error with your Vee Validate syntax, change target: to confirmed:

v-validate="'required|target:password'"

should be

v-validate="'required|confirmed:password'"

Have a look at the basic example below, it will check for two things:

Does the second input field have any input value?
If yes, does the second input value match the first input value?

var app = new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
})

body {
  background: #20262E;
  padding: 15px;
  font-family: Helvetica;
}

#app {
  width: 60%;
  background: #fff;
  border-radius: 10px;
  padding: 15px;
  margin: auto;
}

      <div class="input-fields">
        <input v-validate="'required'" name="password" type="password" placeholder="Password" ref="password">

        <input v-validate="'required|confirmed:password'" name="password_confirmation" type="password" placeholder="Password, Again" data-vv-as="password">
      </div>
    </div>

    <!-- ERRORS -->
    <div class="alert alert-danger" v-show="errors.any()">
      <div v-if="errors.has('password')">
        {{ errors.first('password') }}
      </div>
      <div v-if="errors.has('password_confirmation')">
        {{ errors.first('password_confirmation') }}
      </div>
    </div>

  </form>
</div>
