Remove readonly attributes in Selenium WebDriver

Question

I need to edit some readonly fields with Selenium WebDriver in Java. As Selenium won't let me even find this fields I searched for solutions and found that the easiest might be to remove the readonly attribute using a JavaScript snippet with the JavaScript Executor.

While this snippet works from the Firefox console, successfully removing the attribute from all inputs, it throws an exception in Selenium.

JavaScript executor:

((JavascriptExecutor) driver).executeScript(
    "var inputs = document.getElementsByTagName('input');​​​​"+
    "for(var i = 0; i < inputs.length; i++)"+
        "inputs[i].removeAttribute('readonly','readonly');​​​​"
);

And the error returned:

Exception in thread "main" org.openqa.selenium.WebDriverException: illegal character

Command duration or timeout: 51 milliseconds

UPDATE:

The same error appears if I leave only the first JS command:

((JavascriptExecutor) driver).executeScript(
    "var inputs = document.getElementsByTagName('input');​​​​");

---

The rest of the stack trace is not relevant for this. Anyone knows how to fix this, or another way to edit the readonly fields?

Answer 1

I was not able to find the issue with your code. But in the meantime use the code given below.

List<WebElement> inputs = driver.findElements(By.tagName("input"));

for (WebElement input : inputs) {
    ((JavascriptExecutor) driver).executeScript(
                "arguments[0].removeAttribute('readonly','readonly')",input);
}

Let me know if this helps you.
