Hi,

Hi,

Here is my code, some sites handle file uploads with change event.

(async () => {
	const pw = require("playwright");

	const browser = await pw.firefox.launch({
		headless: true,
	});

	const context = await browser.newContext({
		ignoreHTTPSErrors: true,
		bypassCSP: true,
		userAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0",
		viewport: {
			width: 1920,
			height: 1040,
		}
	});

	const page = await context.newPage();

	page.on("console", msg => {
		console.log(msg.text());
	});

	await page.setContent(`
		<input type=file>
		
		<script>
			document.querySelector('input').addEventListener('change', () => {
				console.log('Changed');
			});

			document.querySelector('input').addEventListener('input', () => {
				console.log('Input');
			});
		</script>
	`);

	const input = await page.$('input[type="file"]');
	await input.setInputFiles(__filename);

	await browser.close();
})();
