Encountering an issue with WebDriver in the realm of JavaScript

I am struggling to use JavaScript to locate specific controls and send values to them. One example is changing the text in a textbox with the ID "ID" to "123456".

Below is the code I tried:

((IJavaScriptExecutor)driver).ExecuteScript("document.getElementById('ID').value='TextValue'");

However, I encountered an error - InvalidOperationException. Prior to this, I successfully used JavaScript to return the page title.

string title = (string)((IJavaScriptExecutor)driver).ExecuteScript("return document.title");

I am unsure of what the problem might be and could use some assistance.

Answer №1

My method for achieving this is as follows:

IWebElement elem = driver.FindElement(By.Id("ID"));
string script = "arguments[0].setAttribute('value', arguments[1])";
driver.ExecuteScript(script, elem, "TextValue");
