如何使用 vue.js 将成功图标添加到我的网页？

Question

大家好，请原谅我的新手，因为我只是一个初学者。

我正在尝试通过使用引导程序或类似的方式将成功图标添加到我的网页，但我不确定如何包含下面显示的 if 语句。

如果有任何建议可以幸免，将不胜感激。

这是我的“AddEntry.vue”模板。

<template>
  <div class="container">
    <RmaForm v-model="rmaEntry" />

    <ActionButton @click="submitItem()" position="1" classes="fas fa-paper-plane" />
  </div>
  
  {{#if alert}}
<div class="alert alert-success alert-dismissible fade show" role="alert">
  <strong>Success!</strong> Data Added to RMA Log. 
  <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
</div>
{{/if}}

</template>

这是我的 index.js 创建入口行

// eslint-disable-next-line
    async createRmaEntry({ state }, payload) {
      return new Promise((resolve, reject) => {
        axios({
          method: "post",
          url: prefix + "/api/rma",
          data: {
            rmaEntry: payload,
          },
          headers: { "Content-Type": "application/json" },
        })
    
          .then(function (response) {
            //handle success
            console.log(response);
            resolve(response.data);
          })
          .catch(function (response) {
            //handle error
            console.log(response);
            reject();
          });
      });
    },

可以使用条件渲染v-if或v-show

new Vue({
  el: "#demo",
  data() {
    return {
      alert: false
    }
  },
  methods: {
    load() {
      // your async call
      setTimeout( ()=> {
        this.alert = true
     }, 1500)
    }
  }
})
