Getting started in EJ2 TypeScript Smart Paste button control
7 Oct 202424 minutes to read
The Smart Paste Button is a user interface control designed to simplify and improve the experience of pasting text into form fields. It comes with smart features such as automatic text formatting, validation, and integration with various form controls. It is especially useful in applications where users frequently paste text from other sources and where data consistency is important.
This section explains how to create a simple Smart Paste button, and configure its available functionalities in TypeScript, using Essential JS 2 quickstart seed repository.
This application is integrated with the
webpack.config.jsconfiguration and uses the latest version of the webpack-cli. It requires nodev14.15.0or higher. For more information about webpack and its features, refer to the webpack documentation.
Prerequisites
To get started, ensure the following software to be installed in the machine.
Check out the download and installation section of
Essential Studio JavaScript. If you are using Syncfusion CDN resources to build your web application, you can skip the Essential Studio JavaScript prerequisite.
Dependencies
The list of dependencies required to use the Smart Paste Button control in your application is given as follows:
|-- @syncfusion/ej2-buttons
|-- @syncfusion/ej2-baseSet up development environment
Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.
git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstartAfter cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.
cd ej2-quickstartAdd Syncfusion JavaScript packages
Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.
The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.
npm installImport the Syncfusion CSS styles
To render Smart Paste Button control, need to import Button and its dependent components styles as given below in the ~/src/styles/index.css file, as shown below:
@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";Adding Smart Paste Button to the Application
Add the HTML Button tag with ID attribute as the smart-paste-button to your index.html file.

<!--Element to render the Smart Paste Button control-->
<button id="smart-paste-button"></button>
</div>
</body>
</html>Then, import the Smart Paste Button control in your app.ts file, and initialize it with the #smart-paste-button.
The control utilizes the aiAssistHandler property, a callback function that sends a request to the AI model and updates the form with the generated content based on the AI’s response.
[src/app/app.ts]
import { SmartPasteButton } from '@syncfusion/ej2-buttons';
const serverAIRequest = async (options: ChatOptions) => {
let output: string | null = '';
try {
// console.log("input:", options);
output = await (window as any).AzureAIRequest(options) as string;
output = output.replace('END_RESPONSE', '')
// console.log("Success:", output);
} catch (error) {
console.error("Error:", error);
}
return output;
};
// Initialize Smart Paste Button control.
let button: SmartPasteButton = new SmartPasteButton({
content: 'Smart Paste',
iconCss: "e-icons e-paste",
aiAssistHandler: serverAIRequest
});
// Render initialized Smart Paste Button.
button.appendTo('#smart-paste');Run the application
Run the application in the browser using the following command:
npm startThe following example shows a basic Smart Paste Button control.
In our demonstration, Azure AI is used, but you can integrate any text-generative AI of your choice.

`Hi, this is Alice. On July 3rd, I've come across a bug where the dropdown menu in the navigation bar doesn't close after selecting an item. I just navigated to the homepage, opened the dropdown menu in the navigation bar, clicked an item in the dropdown and then the issue occurred which happens only on Chrome. Though this doesn't seem like a serious/important bug, kindly look into it and resolve it. Regards, J Alice Abraham`,
`Hey team, On May 2nd, K John Doe reported an issue where the login page refreshes instead of logging in when the user clicks the login button. This problem prevents users from accessing their accounts, making it a critical issue that needs immediate attention. The issue has been observed across all major browsers. To reproduce the issue, open any browser and navigate to the website's login page. Enter a valid username and password, then click the Login button.`,
`Hi, Whenever I type something in the search bar and hit search, it doesn't return any results, even for items I know exist. This problem was noticed by Jane Smith on July 5th in FireFox browser. You can repro the issue by opening the site in the Firefox browser and navigate to the search bar. Type in any search term, including items that are known to exist, and click the search button. The search functionality fails to return any results, displaying an empty result set even for valid queries. This is quite important, but not urgent. Please look into it. Regards, M William Marker`,
`Hello, When I selected the category option on the landing page and chose the electronics category, the images were missing on the product page. The placeholders are there, but no actual images are loading. This happens on all browsers. I reported this on July 3rd. It's not urgent, but it does affect the user experience. Regards, L Mike Johnson`
