The JavascriptExecutor in Selenium WebDriver using C# consistently returns null objects

I'm having trouble accessing HTML elements using jQuery with JavaScriptExecutor and consistently encountering null reference exceptions. Any idea what could be causing this issue?

Below is the code snippet I'm working with:

List<Object> list= (List<Object>)(IJavaScriptExecutor)Browser).ExecuteScript("$('tbody').find('tr')");
list.Count.ShouldBeLessThan(rowsWithNewActivity);

Answer №1

Make sure your JavaScript code is returning a value. Give this a try:

var resultList = ((IJavaScriptExecutor)Browser).ExecuteScript("return $('tbody').find('tr');") as List<object>;

With this modification, the output should no longer be null and instead return the desired list.
