在现代网页开发中,为用户提供及时的反馈对于实现无缝的用户体验至关重要。 Toast 通知是一种在不干扰用户工作流程的情况下传递信息的有效方式。 "(《世界人权宣言》)React-toastify该包是 React 应用中实现 toast 通知的热门选择,因为它简单且灵活。 我们还将调查IronPDF用于生成、编辑和管理PDF文档的NPM软件包。 本文将指导您完成集成过程React-toastify和IronPDF到你的React项目中。
React-toastify是一个 NPM 包,可以让您以最小的设置为 React 应用程序添加可自定义的 toast 通知。它提供了多种功能,包括不同的通知类型、自动关闭功能、自定义样式、剩余时间显示等。
入门react-toastify,您需要通过NPM或Yarn安装该软件包。 在项目的根目录中运行以下命令:
npm install react-toastify
npm install react-toastify
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npm install react-toastify
或
yarn add react-toastify
yarn add react-toastify
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'yarn add react-toastify
安装软件包后,您可以在 React 应用程序中开始使用 react-toastify。 下面是一个简单的代码示例,演示如何集成和使用 react-toastify。
首先,您需要从 react-toastify 导入必要的组件:
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'import React from 'react'; import { ToastContainer, toast } from 'react-toastify'; import 'react-toastify/dist/ReactToastify.css';
接下来,将 ToastContainer 组件添加到您的应用程序中。
function App() {
return (
<div> // react component rendered inside
<ToastContainer />
</div>
);
}
function App() {
return (
<div> // react component rendered inside
<ToastContainer />
</div>
);
}
Private Function App() As [function]
'INSTANT VB WARNING: Instant VB cannot determine whether both operands of this division are integer types - if they are then you should use the VB integer division operator:
Return ((Of div) <ToastContainer /> </div>)
End Function
您可以使用toast函数触发一个toast通知。 以下是显示成功消息的代码示例:
function notify() {
toast.success("Success! This is a success message.", {
position: toast.POSITION.TOP_RIGHT
});
}
function App() {
return (
<div>
<button onClick={notify}>Show Toast</button>
<ToastContainer /> // react component inside
</div>
);
}
function notify() {
toast.success("Success! This is a success message.", {
position: toast.POSITION.TOP_RIGHT
});
}
function App() {
return (
<div>
<button onClick={notify}>Show Toast</button>
<ToastContainer /> // react component inside
</div>
);
}
Private Function notify() As [function]
toast.success("Success! This is a success message.", { position:= toast.POSITION.TOP_RIGHT })
End Function
Private Function App() As [function]
'INSTANT VB TODO TASK: The following line contains an assignment within expression that was not extracted by Instant VB:
'ORIGINAL LINE: return (<div> <button onClick={notify}> Show Toast</button> <ToastContainer /> </div>);
'INSTANT VB WARNING: Instant VB cannot determine whether both operands of this division are integer types - if they are then you should use the VB integer division operator:
Return ((Of div) <button onClick={AddressOf notify}> Show Toast</button> <ToastContainer /> </div>)
End Function
React-toastify提供多种高级功能,允许您使用onOpen和onClose钩子来自定义吐司的行为和外观。
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
function App() {
const notify = () => {
toast("Hello there", {
onOpen: () => window.alert('Called when I open'),
onClose: () => window.alert('Called when I close')
});
};
return (
<div>
<button onClick={notify}>Notify</button>
<ToastContainer />
</div>
);
}
export default App;
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
function App() {
const notify = () => {
toast("Hello there", {
onOpen: () => window.alert('Called when I open'),
onClose: () => window.alert('Called when I close')
});
};
return (
<div>
<button onClick={notify}>Notify</button>
<ToastContainer />
</div>
);
}
export default App;
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'import React from 'react'; import { ToastContainer, toast } from 'react-toastify'; import 'react-toastify/dist/ReactToastify.css'; @function App() { const notify = () => { toast("Hello there", { onOpen: () => window.alert('Called @when I open'), onClose: () => window.alert('Called @when I close') }); }; Return(<div> <button onClick={notify}> Notify</button> <ToastContainer /> </div>); } export default App;
在此示例中:
您可以使用位置选项在屏幕的不同位置显示提示信息:
toast.info("Information message", {
position:"top-right"
});
toast.info("Information message", {
position:"top-right"
});
toast.info("Information message", { position:="top-right" })
您可以使用 autoClose 选项设置烤面包消息显示的持续时间:
toast.warn("Warning message", {
autoClose: 5000 // Auto close after 5 seconds
});
toast.warn("Warning message", {
autoClose: 5000 // Auto close after 5 seconds
});
toast.warn("Warning message", { autoClose:= 5000 })
可以使用 className 和样式选项自定义样式。
toast.error("Error message", {
className: 'custom-toast',
style: { background: 'red', color: 'white' }
});
toast.error("Error message", {
className: 'custom-toast',
style: { background: 'red', color: 'white' }
});
toast.error("Error message", { className: 'custom-toast', style: { background: 'red', color: 'white' } });
可以使用 toast.dismiss 方法以编程方式关闭 Toast:
const toastId = toast("This toast can be dismissed");
function dismissToast() {
toast.dismiss(toastId);
}
const toastId = toast("This toast can be dismissed");
function dismissToast() {
toast.dismiss(toastId);
}
Private const toastId = toast("This toast can be dismissed")
Private Function dismissToast() As [function]
toast.dismiss(toastId)
End Function
以下是一个完整的示例,展示了如何使用各种 react-toastify 功能:
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
function App() {
const notify = () => {
toast.success("Success! This is a success message.", {
position:"top-right" // success notification
});
toast.info("Information message", {
position:"bottom-left" // info will be displayed with progress bar
});
toast.warn("Warning message", {
autoClose: 5000 // close or pause toast messages
});
toast.error("Error message", {
className: 'custom-toast',
style: { background: 'red', color: 'white' }
});
};
return (
<div>
<button onClick={notify}>Show Toasts</button>
<ToastContainer />
</div>
);
}
export default App;
import React from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
function App() {
const notify = () => {
toast.success("Success! This is a success message.", {
position:"top-right" // success notification
});
toast.info("Information message", {
position:"bottom-left" // info will be displayed with progress bar
});
toast.warn("Warning message", {
autoClose: 5000 // close or pause toast messages
});
toast.error("Error message", {
className: 'custom-toast',
style: { background: 'red', color: 'white' }
});
};
return (
<div>
<button onClick={notify}>Show Toasts</button>
<ToastContainer />
</div>
);
}
export default App;
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'import React from 'react'; import { ToastContainer, toast } from 'react-toastify'; import 'react-toastify/dist/ReactToastify.css'; @function App() { const notify = () => { toast.success("Success!

由于IronPDF仅在Node.js上运行,接下来为应用程序添加一个在Node.js中生成PDF的API。
在 pages/api 文件夹中创建一个名为 pdf.js 的文件,并添加以下代码。
