Playwright: Get the locator by alt text

You can use page.getByAltText method to locate the elements by their alt text.

 

Example

ElementHandle elementHandle = page.getByAltText("plantuml").elementHandle();

 

Find the below working application.

 

altDemo.html

<!DOCTYPE html>
<html>

<body>

	<h1>alt attribute demo</h1>

	<img src="plantuml.webp" width="200" height="200" alt="plantuml">

</body>

</html>

FileUtil.java

package com.sample.app.util;

import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class FileUtil {

	public static String resourceAsString(String resourceName) throws IOException {
		ClassLoader classLoader = FileUtil.class.getClassLoader();
		URL url = classLoader.getResource(resourceName);
		if (url == null) {
			return null;
		}

		URLConnection urlConnection = url.openConnection();

		urlConnection.setUseCaches(false);

		try (InputStreamReader inputStreamReader = new InputStreamReader(urlConnection.getInputStream())) {
			char[] buffer = new char[1048];
			StringBuilder builder = new StringBuilder();

			int count = -1;
			while ((count = inputStreamReader.read(buffer, 0, buffer.length)) != -1) {
				builder.append(buffer, 0, count);
			}

			return builder.toString();
		}

	}
}

GetByAltText.java

package com.sample.app.locators;

import java.io.File;
import java.io.IOException;

import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.ElementHandle;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
import com.sample.app.util.FileUtil;

public class GetByAltText {
	public static void main(String[] args) throws IOException {
		try (Playwright playwright = Playwright.create()) {

			Browser browser = playwright.chromium()
					.launch(new BrowserType.LaunchOptions().setHeadless(false).setSlowMo(100));

			final String content = FileUtil.resourceAsString("locators" + File.separator + "altDemo.html");

			Page page = browser.newPage();
			page.setContent(content);

			ElementHandle elementHandle = page.getByAltText("plantuml").elementHandle();
			String src = elementHandle.getAttribute("src");
			System.out.println("This element points to the src : " + src);
		}
	}
}

Output

This element points to the src : plantuml.webp
