Guidelines on Transferring Variables to a JavascriptExecutor Script

Currently, I am utilizing C# and Selenium to browse through a website and have come across an issue regarding passing variables into my JavaScriptExecutor command. When I attempt to do so using the code below:

((IJavaScriptExecutor)webdriver).ExecuteScript("document.getElementByID('text box1').value = 'hello'");

Everything runs smoothly. However, when I try to use variables instead, it gives me an error stating that they are not defined:

var elementID = "text box1"
var fieldValue = "hello"
((IJavaScriptExecutor)webdriver).ExecuteScript("document.getElementByID(elementID).value = fieldValue");

Answer №1

If you need to pass variables into a JavaScriptExecutor command, try this solution:

var elementID = "inputField"
var textValue = "goodbye"
((IJavaScriptExecutor)driver).ExecuteScript("document.getElementById('" + elementID + "').value ='" + textValue + "'");

Note: It's crucial to use document.getElementById() instead of document.getElementByID(). Pay attention to the letter case in Id.
