问题描述

我想在我的Vue3应用程序中对PrimeVue元素应用一些边距。基于文档中的示例

https://www.primefaces.org/primevue/showcase/#/selectbutton

我有一个在图标和文本之间留有边距的工作示例

                <template #option="slotProps">
                    <i class="pi pi-check-circle" />
                    <span class="p-ml-4">Some text</span>
                </template>
            </p-selectbutton>
        </div>

        <script type="module">
        const { createApp, ref } = Vue;

        const App = {
            setup() {
                const selectedValue = ref();
                
                const options = ref([
                    { value: 'left' },
                    { value: 'right' }
                ]);

                return { selectedValue, options }
            },
            components: {
                "p-selectbutton": primevue.selectbutton
            }
        };

        createApp(App)
            .use(primevue.config.default)
            .mount("#app");
        </script>

    </body>
</html>

但边距在我的项目中不起作用。用于复制:

vue create foo

# select default Vue3 app

cd foo

# based on https://primefaces.org/primevue/showcase/#/setup

npm install primevue

npm install primeicons

npm install primeflex

我将main.js文件更改为

import { createApp } from 'vue'
import PrimeVue from "primevue/config";
import "primevue/resources/themes/saga-blue/theme.css";
import "primevue/resources/primevue.min.css";
import "primeicons/primeicons.css";
import "primeflex/primeflex.css";
import SelectButton from "primevue/selectbutton";
import App from './App.vue'

createApp(App)
    .use(PrimeVue)
    .component("p-select-button", SelectButton)
    .mount('#app')

我将App.vue文件更改为

<template>
  <p-select-button v-model="selectedValue" :options="options" dataKey="value">
      <template #option>
          <i class="pi pi-check-circle" />
          <span class="p-ml-4">Some text</span>
      </template>
  </p-select-button>
</template>

<script>
import { ref } from "vue";

export default {
  setup() {
    const selectedValue = ref();
    
    const options = ref([
        { value: 'left' },
        { value: 'right' }
    ]);

    return { selectedValue, options }
  },
}
</script>

运行应用程序时,结果为

有人知道为什么边距在第一个示例中有效,但在我的代码中不起作用吗?我错过了什么?

推荐答案

您的CDN演示使用的是PrimeFlex2:

<link href="https://unpkg.com/[email protected]/primeflex.min.css" rel="stylesheet" />
                                        👆

但您的应用程序使用的是PrimeFlex 3(即npm install primeflex安装3.1.0)。最新版本为removed the p- prefix from all classnames for readability,因此class name is now ml-4

解决方案1:将类名称更新为ml-4

您可以在App.vue中使用PrimeFlex 3的类名:

<!-- BEFORE -->
<span class="p-ml-4">Some text</span>

<!-- AFTER -->
<span class="ml-4">Some text</span>

demo 1

解决方案2:降级到PrimeFlex 2

如果您更喜欢使用现有版本(可能是为了最大限度地减少大型应用程序中的更改),请安装PrimeFlex 2:

npm install -S primeflex@2
