ConsoleMessage

ConsoleMessage 对象通过 Page.onConsoleMessage(handler) 事件按页分派。对于页面中记录的每条控制台消息，Playwright 上下文中都会有相应的事件。

¥ConsoleMessage objects are dispatched by page via the Page.onConsoleMessage(handler) event. For each console message logged in the page there will be corresponding event in the Playwright context.

// Listen for all console messages and print them to the standard output.
page.onConsoleMessage(msg -> System.out.println(msg.text()));

// Listen for all console messages and print errors to the standard output.
page.onConsoleMessage(msg -> {
  if ("error".equals(msg.type()))
    System.out.println("Error text: " + msg.text());
});

// Get the next console message
ConsoleMessage msg = page.waitForConsoleMessage(() -> {
  // Issue console.log inside the page
  page.evaluate("console.log('hello', 42, { foo: 'bar' });");
});

// Deconstruct console.log arguments
msg.args().get(0).jsonValue(); // hello
msg.args().get(1).jsonValue(); // 42
