org.openqa.selenium.WebDriverException: Error occurred: Runtime.evaluate encountered an issue: SyntaxError: Token is invalid or unexpected

I'm encountering an issue while trying to execute the following code using Selenium webdriver

The code snippet is:

    WebElement w=driver.findElement(By.xpath("//*[@class='tab']"));

    JavascriptExecutor js=(JavascriptExecutor) driver;

    js.executeScript("arguments[0].setAttribute('disable,'');",w);

The error message reads:

org.openqa.selenium.WebDriverException: unknown error: Runtime.evaluate threw exception: SyntaxError: Invalid or unexpected token

Answer №1

It seems that you have forgotten to use quotation marks. This could be a simple typo mistake.

js.executeScript("arguments[0].setAttribute('disable','');",w);

Answer №2

Dealing with a similar issue, I found a solution that worked for me:

element.sendKeys("5'7");

If your data contains a single quote, make sure to escape it with a backslash. You can achieve this in Java with the following code snippet:

String text = "5'7";
text = text.replace("'", "\\'");
element.sendKeys(text);

By implementing this change, the data will be sent as "5'7" instead of "5'7".

Answer №3

Murthi pointed out that the main issue is the absence of quotes.

If you are planning to utilize selenium (Python) in conjunction with JavaScript to input text from Python, it is advisable to use json.dumps(python_str)

It's important to note that json dumps automatically adds quotes, so make sure not to enclose the string in quotes when using it in JavaScript

'test.innerText = "{}";'.format(json_dumps(python_str))

JavaScript will interpret it as follows: 

'test.innerText = ""hello world"";
, resulting in a sys error:

javascript error: Unexpected identifier hello

If single quotes are used, there will be double quotes within the string

To resolve this issue, avoid adding additional single or double quotes since json.dumps already includes them

"test.innerText = {};".format(json_dumps(python_str))

Additionally, replace all quotes with HTML entity codes

python_str = python_str.replace("'", "'").replace('"', """).replace('`', '`')
