                    <b-button  variant="danger" size="sm" class="mt-2 ml-2" @click="hidePinModal">Cancel</b-button>
                </div>
            </b-modal>
        </div>

这是我的 bootstrapVue 示例代码。我还附上了输出图像。

如何将标题“确认批准”设为中心？

Answer 1

或者使用标题插槽。
您可以使用 header-class Prop ，并添加 justify-content-center实用程序类，将标题居中。

new Vue({
  el: '#my-app',
  data: {
    comment: 'Some comment',
    pin: ''
  }
});

<link type="text/css" rel="stylesheet" href="https://unpkg.com/bootstrap/dist/css/bootstrap.min.css" />
<link type="text/css" rel="stylesheet" href="https://unpkg.com/bootstrap-vue@2.21.2/dist/bootstrap-vue.min.css" />
<script src="https://unpkg.com/vue@2.6.2/dist/vue.min.js"></script>
<script src="https://unpkg.com/bootstrap-vue@2.21.2/dist/bootstrap-vue.min.js"></script>

<div id="my-app">
  <b-modal visible centered id="send-pin-modal" header="test" header-class="justify-content-center" title="Confirm Approval" hide-footer hide-header-close no-close-on-backdrop no-close-on-esc>
    <div class="col-12">
      <div class="ml-5 mr-5">
        <b-form-input type="password" id="pin-input" v-model="pin" required></b-form-input>
      </div>
    </div>
    <div class="col-12 text-center">
      <slot name="pin-error" class="text-danger text-center" v-show="comment">{{comment}}</slot>
    </div>
    <div class="col-12">
    </div>
    <div class="col-12 text-center">
      <b-button variant="primary" size="sm" class="mt-2 mr-2">Continue</b-button>
      <b-button variant="danger" size="sm" class="mt-2 ml-2">Cancel</b-button>
    </div>
  </b-modal>
</div>
