将 Sweet Alert 弹出窗口添加到 React 组件中的按钮
Add Sweet Alert popup to button in React component
我为 Bootstrap 和 React(我在我的 Meteor 应用程序中使用)找到了这个完美的 Sweet Alert 模块:
http://djorg83.github.io/react-bootstrap-sweetalert/
但我不明白你是如何将这段代码包含在 React 组件中的。
当有人在我的应用程序中单击“删除”按钮时,我希望弹出一个 Sweet Alert 提示,要求确认。
这是我的删除按钮组件:
import React, {Component} from 'react';
import Goals from '/imports/collections/goals/goals.js'
import SweetAlert from 'react-bootstrap-sweetalert';
export default class DeleteGoalButton extends Component {
deleteThisGoal(){
console.log('Goal deleted!');
// Meteor.call('goals.remove', this.props.goalId);
}
render(){
return(
<div className="inline">
<a onClick={this.deleteThisGoal()} href={`/students/${this.props.studentId}/}`}
className='btn btn-danger'><i className="fa fa-trash" aria-hidden="true"></i> Delete Goal</a>
</div>
)
}
}
下面是我从 Sweet Alert 示例中复制的代码:
<SweetAlert
warning
showCancel
confirmBtnText="Yes, delete it!"
confirmBtnBsStyle="danger"
cancelBtnBsStyle="default"
title="Are you sure?"
onConfirm={this.deleteFile}
onCancel={this.cancelDelete}
>
You will not be able to recover this imaginary file!
</SweetAlert>
有人知道怎么做吗?
基于您的代码的工作示例http://www.webpackbin.com/VJTK2XgQM
您应该使用 this.setState()
并在 onClick
上创建 <SweetAlert ... />
。您可以使用粗箭头或 .bind()
或任何其他方法来确保使用了正确的上下文。
import React, {Component} from 'react';
import SweetAlert from 'react-bootstrap-sweetalert';
export default class HelloWorld extends Component {
constructor(props) {
super(props);
this.state = {
alert: null
};
}
deleteThisGoal() {
const getAlert = () => (
<SweetAlert
success
title="Woot!"
onConfirm={() => this.hideAlert()}
>
Hello world!
</SweetAlert>
);
this.setState({
alert: getAlert()
});
}
hideAlert() {
console.log('Hiding alert...');
this.setState({
alert: null
});
}
render() {
return (
<div style={{ padding: '20px' }}>
<a
onClick={() => this.deleteThisGoal()}
className='btn btn-danger'
>
<i className="fa fa-trash" aria-hidden="true"></i> Delete Goal
</a>
{this.state.alert}
</div>
);
}
}
如果您公开@hinok 解决方案的方式对某些人不起作用,那么您可以像这样修改此函数:
deleteThisGoal() {
this.setState({
alert: ( <
SweetAlert success title = "Woot!"
onConfirm = {
() => this.hideAlert()
} >
Hello world!
<
/SweetAlert>
)
});
};
这是我写的代码:
showAlert(title, message, callBack, style) {
this.setState({
alert: (
<SweetAlert
warning
showCancel
confirmBtnText = "Sí"
cancelBtnText = "No"
confirmBtnBsStyle= {style ? style : "warning"}
cancelBtnBsStyle = "default"
customIcon = "thumbs-up.jpg"
title = {title}
onConfirm = {callBack()}
onCancel = {this.hideAlert}
>
{message}
</SweetAlert>
)
});
}
hideAlert = () => {
this.setState({
alert: null
});
}
updateCustomer = () => {..."a few lines of code here"}
这是从按钮调用的:
{<Button color="primary" disabled={this.state.notChange} onClick={() => this.showAlert('Save changes for client', '¿Are you sure?', () => this.updateCustomer, null) } >Save changes</Button>}
