How to get the webpage title using JavaScript executor

I am new bee of the automation testing. On my code, I am using the JavaScript on my Selenium automation test script (on using the JUnit). I am trying to find the current window title:

driver = new ChromeDriver();
js = (JavaScriptExecutor)driver;

driver.get(//passed url);

//after the log in my Org. I execute the command below

//to get the title of the current window I execute the below command        
js.executeScript("document.getElementsByTagName('title').innerHTML;");

But the above command will return the answer as the null instant of getting the title of the window. So does anyone know what's wrong with my command?

But I get the title of the window on executing on the console log of the page. So I don't know what's wrong with my code.

Thanks.

Solution

  • Change the following line:

    document.getElementsByTagName('title').innerHTML

    to:

    return document.getElementsByTagName('title')[0].innerHTML

    in code it will be:

    js.executeScript("return document.getElementsByTagName('title')[0].innerHTML;");

    getElementsByTagName returns array of elements. So we need to pass the index value.

    Web driver interface provides get title method. It is very simple.

    String title=driver.getTitle();
System.out.println("Title is" + title);
