使用ant-design-vue的Form表單

使用腳手架新建項(xiàng)目

vue create antd-demo

所以，得到了這么一個(gè)項(xiàng)目，如下

安裝并導(dǎo)入ant-design-vue,使用Form組件

npm install --save ant-design-vue@next

修改main.ts

import { createApp } from 'vue';
import App from './App.vue';
import Antd from "ant-design-vue";
import "ant-design-vue/dist/antd.css";
createApp(App).use(Antd).mount('#app');

修改App.vue

<template>
? <HelloWorld/>
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import HelloWorld from './components/HelloWorld.vue';
export default defineComponent({
? name: 'App',
? components: {
? ? HelloWorld
? }
});
</script>

<style>
#app {
? font-family: Avenir, Helvetica, Arial, sans-serif;
? -webkit-font-smoothing: antialiased;
? -moz-osx-font-smoothing: grayscale;
? text-align: center;
? color: #2c3e50;
? margin-top: 60px;
}
</style>

修改HelloWorld.vue

<template>
? <a-form
? ? layout="inline"
? ? :model="formState"
? ? @finish="handleFinish"
? ? @finishFailed="handleFinishFailed"
? >
? ? <a-form-item>

? ? ? <a-button

? ? ? >
? ? ? ? Log in
? ? ? </a-button>
? ? </a-form-item>
? </a-form>
</template>

<script lang="ts">

</script>

啟動(dòng)應(yīng)用,測(cè)試驗(yàn)證

npm run serve啟動(dòng)應(yīng)用，效果如下

好了，應(yīng)用就暫時(shí)介紹到這里。其實(shí)，我更想說(shuō)說(shuō)我的疑惑：

Hello.vue中，Username輸入框的前面有個(gè)圖片前綴，Password輸入框的前面也有一個(gè)圖片前綴，都是通過(guò)<template #prefix></template>實(shí)現(xiàn)的，一眼看去，應(yīng)該就是通過(guò)插槽實(shí)現(xiàn)的，但是具體的實(shí)現(xiàn)過(guò)程是怎樣的，尚不清楚。

簡(jiǎn)單調(diào)試了一下，如下圖所示。
