使用ant-design-vue的Form表单
使用脚手架新建项目
vue create antd-demo
所以，得到了这么一个项目，如下
安装并导入ant-design-vue,使用Form组件
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-input v-model:value="formState.user" placeholder="Username"> <template #prefix><UserOutlined style="color: rgba(0, 0, 0, 0.25)" /></template> </a-input> </a-form-item> <a-form-item> <a-input v-model:value="formState.password" type="password" placeholder="Password"> <template #prefix><LockOutlined style="color: rgba(0, 0, 0, 0.25)" /></template> </a-input> </a-form-item> <a-form-item> <a-button type="primary" html-type="submit" :disabled="formState.user === '' || formState.password === ''" > Log in </a-button> </a-form-item> </a-form> </template>
<script lang="ts">
import { UserOutlined, LockOutlined } from '@ant-design/icons-vue';
import { ValidateErrorEntity } from 'ant-design-vue/es/form/interface';
import { defineComponent, reactive, UnwrapRef } from 'vue';
interface FormState {
user: string;
password: string;
}
export default defineComponent({
setup() {
const formState: UnwrapRef<FormState> = reactive({
user: '',
password: '',
});
const handleFinish = (values: FormState) => {
console.log(values, formState);
};
const handleFinishFailed = (errors: ValidateErrorEntity<FormState>) => {
console.log(errors);
};
return {
formState,
handleFinish,
handleFinishFailed,
};
},
components: {
UserOutlined,
LockOutlined,
},
});
</script>启动应用,测试验证
npm run serve启动应用，效果如下
好了，应用就暂时介绍到这里。其实，我更想说说我的疑惑：
Hello.vue中，Username输入框的前面有个图片前缀，Password输入框的前面也有一个图片前缀，都是通过<template #prefix></template>实现的，一眼看去，应该就是通过插槽实现的，但是具体的实现过程是怎样的，尚不清楚。
简单调试了一下，如下图所示。
ant-design-vue的Form组件的FormItem.js的部分源码如下，
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
