using document.readyState correctly with Selenium

Question

I'm searching for a way to scroll down to a page that loads content as it is scrolled, to have everything loaded before I start interacting with it using Selenium.

I found this code below which was posted for c#, I changed it to Java. It compiles and runs. But even though the page reaches the end, it does not get out of the loop

        Boolean readyStateComplete = false;
        while (!readyStateComplete)
        {
            JavascriptExecutor executor = (JavascriptExecutor) driver;
            executor.executeScript("window.scrollTo(0, document.body.offsetHeight)");
            readyStateComplete = (String) executor.executeScript("return document.readyState") == "complete";
        }

I don't know much about Javascript. How can this be corrected?

Answer 1

Please try .equals() method instead of == i means

readyStateComplete = ((String) executor.executeScript("return document.readyState")).equals("complete"); 

== tests for reference equality (whether they are the same object).

.equals() tests for value equality (whether they are logically "equal").
