我正在使用版本:
react@16.8.6
react-bootstrap@1.0.0-beta.8
我有一个简单的模态组件:
import React, { Component } from 'react'
import { Modal } from "react-bootstrap";
import { ProgressBar } from "react-bootstrap";
class ProgressModal extends Component {
constructor(...args) {
super(...args);
this.state = { showModal: false, titleText: ((this.props.titletext === undefined || this.props.titletext === null || this.props.titletext === "") ? "Working..." : this.props.titletext)};
this.open = this.open.bind(this);
this.close = this.close.bind(this);
}
open() {
this.setState({showModal: true});
}
close() {
this.setState({showModal: false});
}
render() {
return (
<Modal centered backdrop="static" keyboard={false} {...this.props}>
<Modal.Header>
<Modal.Title className="font-weight-bold">{this.state.titleText}</Modal.Title>
</Modal.Header>
<Modal.Body>
<ProgressBar animated striped now={100} />
</Modal.Body>
</Modal>
);
}
}
export default ProgressModal;
此功能旨在为长时间运行的活动(例如登录)打开。我想在用户单击登录按钮时将其打开,然后在登录完成后将其关闭。除了使用模态窗口内部的关闭按钮外,我很难找到其他方法来关闭它:
<Button className="btn-block" variant="danger" onClick={this.props.onHide}>Close</Button>
这当然只允许用户在需要时将其关闭。我已经在要从外部组件调用的组件中添加了一个open和close方法。
我尝试了很多事情:
添加一个id,使用getElementById查找它,然后触发该方法。
Adding a ref to the opening component as described here.
Doing it programmatically as described here.
I got some ideas from this question on how to call methods in other components.
话虽如此,我仍然无法从模态组件本身外部自动关闭模态窗口。
答案 0 :(得分:0)
这就是我最终要做的。我无法使用'ref'逻辑,所以最终在构造函数中使用了全局引用:
window.progressModal = this;
我还需要更改关闭代码,因为将showModal状态变量设置为false并不能关闭模态窗口。将showModal设置为true确实会打开窗口:
<Modal id={"progress-bar-modal-window"} show={this.state.showModal} centered backdrop="static" keyboard={false} {...this.props}>
open() {
this.setState({showModal: true});
}
close() {
this.props.onHide();
}
现在,外部组件可以使用以下方式打开模式窗口:
window.progressModal.open();
,他们可以使用以下命令将其关闭:
window.progressModal.close();
