ConsoleMessage

ConsoleMessage 对象通过 page.on('console') 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.on('console') event. For each console message logged in the page there will be corresponding event in the Playwright context.

// Listen for all console logs
page.on('console', msg => console.log(msg.text()));

// Listen for all console events and handle errors
page.on('console', msg => {
  if (msg.type() === 'error')
    console.log(`Error text: "${msg.text()}"`);
});

// Get the next console log
const msgPromise = page.waitForEvent('console');
await page.evaluate(() => {
  console.log('hello', 42, { foo: 'bar' });  // Issue console.log inside the page
});
const msg = await msgPromise;

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