How to use Javascriptexecutor for entering text in an element which does not have Id as a locator?

Question

I want to enter text in an Textbox which does not take the input through SendKeys. I proceeded with using Javascriptexecutor to enter the text and succeeded. Now there are a few fields in which there is no Id that can be selected as a locator so I need to locate them with Xpath. I would like to know how can we locate the element by xpath in Javascriptexecutor and pass the values to it.

JavascriptExecutor jse = (JavascriptExecutor)driver
jse.executeScript("document.getElementById('value').value='1611 
Dragons';");

I need an approach where I can use it something like:

document.getElementByXpath("Xpath Here").value='xyz';");

Please feel free to guide me to a Doc/answer if it documented somewhere before.

Solution

Try the following code, it would solve your problem:

 WebElement element = driver.findElement(By.xpath("enter the xpath here"));
 JavascriptExecutor jse = (JavascriptExecutor)driver;
 jse.executeScript("arguments[0].value='enter the value here';", element);
