在实际的业务场景中,form表单里面提交upload是一个非常普遍的应用场景。
这里记录下,自己使用form表单,upload图片的代码。
话不多说 ,直接上代码。
封装一下upload组件
import * as React from 'react';
import { Icon, Modal, Upload } from 'antd';
export default class PallWrop extends React.Component {
state = {
previewVisible: false,
previewImage: '',
};
handlePreview = file => {
this.setState({
previewImage: file.url || file.thumbUrl,
previewVisible: true,
});
};
render() {
const { fileList, imgNumber,onChange } = this.props;
const list = fileList||[]
const { previewVisible, previewImage } = this.state;
const uploadButton = (
<div>
<Icon type="plus" />
<div className="ant-upload-text">Upload</div>
</div>
);
return (
<div className="clearfix">
<Upload
action="http://localhost:7001/api/upload"
listType="picture-card"
fileList={list}
onChange={onChange}
onPreview={this.handlePreview}
>
{list.length >= imgNumber ? null : uploadButton}
</Upload>
<Modal visible={previewVisible} footer={null} onCancel={this.handleCancel}>
<img alt="example" style={{ width: '100%' }} src={previewImage} />
</Modal>
</div>
);
}
}
父组件
import React from 'react';
import { Form } from 'antd';
import PallWrop from './PallWrop';
const FormItem = Form.Item;
@Form.create()
export default class Test extends React.Component {
state = {
fileList: [
{
status: 'done',
uid: 0,
url: 'http://localhost:7001/public/images/kele.jpg',
},
],
};
componentDidMount() {
const { form } = this.props;
const { fileList } = this.state;
form.setFieldsValue({ pictures: fileList });
}
handleOnChange = ({ fileList }) => {
console.log(fileList)
return fileList.map(file => ({
status: file.status,
uid: file.uid,
url: file.response?file.response.data.url:file.url,
}));
};
render() {
const {
form: { getFieldDecorator },
form,
} = this.props;
form.validateFields((error, fields) => {
console.log(fields);
});
return (
<div>
<Form>
<FormItem label={'商店实景图'}>
{getFieldDecorator('pictures', {
valuePropName: 'fileList',
getValueFromEvent: this.handleOnChange,
})(<PallWrop imgNumber={3} />)}
</FormItem>
<FormItem label={'商店实景图'}>
{getFieldDecorator('ddd', {
valuePropName: 'fileList',
getValueFromEvent: this.handleOnChange,
})(<PallWrop imgNumber={1} />)}
</FormItem>
</Form>
</div>
);
}
}
这里说下,在formitem中,需要监听下handleOnChange ,子组件的回调,这里可以设置fileList传递的数据格式。 不太会言语,有问题可以留言~~
这里action的地址我填的是我本地的,请注意替换成对应的url
