Bug Description

when i run

() => { const finalBtn = document.querySelector('div.contact-boxes.ng-star-inserted'); if (finalBtn) { return finalBtn.innerHTML; } else { return "Element not found"; } } i get

{'id': 19, 'result': {'result': {'type': 'object', 'subtype': 'error', 'className': 'SyntaxError', 'description': 'SyntaxError: Illegal return statement', 'objectId': '7549169250272292091.6.2'}, 'exceptionDetails': {'exceptionId': 1, 'text': 'Uncaught', 'lineNumber': 2, 'columnNumber': 36, 'scriptId': '40', 'exception': {'type': 'object', 'subtype': 'error', 'className': 'SyntaxError', 'description': 'SyntaxError: Illegal return statement', 'objectId': '7549169250272292091.6.3'}}}}

Steps to Reproduce

i run

await page.execute_script("""
                                       () => {
            const finalBtn = document.querySelector('div.contact-boxes.ng-star-inserted');
            if (finalBtn) {
                return finalBtn.innerHTML;
            } else {
                return "Element not found";
            }
        }
                                    """)

i even tried the one in docs title = await page.execute_script('return document.title')

Code Example

async with Chrome() as browser:
        await browser.start()
        page = await browser.get_page()
        await page.go_to(url)

        # Extract data
        title = await page.execute_script('return document.title')

Expected Behavior

hi @dragonscraper , You can use execute_script to achieve all commands that can be done in the console.:

async def main():
    async with Chrome() as browser:
        await browser.start()
        page = await browser.get_page()

        await page.go_to('https://github.com/')
        title = await page.execute_script("""document.title""")
        result = await page.execute_script("""
        (function() {             
            const finalBtn = document.querySelector('div.contact-boxes.ng-star-inserted');
            if (finalBtn) {
                return finalBtn.innerHTML;
            } else {
                return "Element not found";
            }})();
        """)

Hi @dragonscraper,

This is a known bug that will be fixed in the next release. For now, execute_command can only run the same code you'd be able to execute in the browser console. So, to use return, you'll need to place your code inside a function. I ask for a bit of patience, his will become more intuitive soon

[dragonscraper]

yes that's why i did wrapped it in a function thanks for your efforts

print(await web_element._execute_script('(webElement) => webElement.toDataURL()')) throws an error print(await web_element.evaluate('(webElement) => webElement.toDataURL()') works with playwright

print(await web_element._execute_script('(function() { return this.toDataURL();})')) works right now
