代碼演示

基礎用法

<!-- 密碼輸入框 -->
<van-password-input
  :value="value"
  info="密碼為 6 位數(shù)字"
  :focused="showKeyboard"
  @focus="showKeyboard = true"
/>
<!-- 數(shù)字鍵盤 -->
<van-number-keyboard
  :show="showKeyboard"
  @input="onInput"
  @delete="onDelete"
  @blur="showKeyboard = false"
/>

export default {
  data() {
    return {
      value: '123',
      showKeyboard: true
    };
  },
  methods: {
    onInput(key) {
      this.value = (this.value + key).slice(0, 6);
    },
    onDelete() {
      this.value = this.value.slice(0, this.value.length - 1);
    }
  }
}

自定義長度

<van-password-input
  :value="value"
  :length="4"
  :gutter="15"
  :focused="showKeyboard"
  @focus="showKeyboard = true"
/>

明文展示

<van-password-input
  :value="value"
  :mask="false"
  :focused="showKeyboard"
  @focus="showKeyboard = true"
/>

錯誤提示

通過error-info屬性可以設置錯誤提示信息，例如當輸入六位時提示密碼錯誤

<!-- 密碼輸入框 -->
<van-password-input
  :value="value"
  :error-info="errorInfo"
  :focused="showKeyboard"
  @focus="showKeyboard = true"
/>
<!-- 數(shù)字鍵盤 -->
<van-number-keyboard
  :show="showKeyboard"
  @input="onInput"
  @delete="onDelete"
  @blur="showKeyboard = false"
/>

export default {
  data() {
    return {
      value: '123',
      showKeyboard: true,
      errorInfo: ''
    };
  },
  methods: {
    onInput(key) {
      this.value = (this.value + key).slice(0, 6);
      if (this.value.length === 6) {
        this.errorInfo = '密碼錯誤';
      } else {
        this.errorInfo = '';
      }
    },
    onDelete() {
      this.value = this.value.slice(0, this.value.length - 1);
    }
  }
}
