Question

I want to use javascript to locate the controls and send value to it.
For example I want to change the text in the textbox(id=”ID”) into “123456”.

Here comes my code:

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

but something get error. it show invalidoperateException.
Before this I try to use javascript to return the title and it works.

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

I cannot figure out what the problem is.

Here’s how I do it:

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