If you want to read text of any element using javascript executor  you can do something like following code   WebElement ele   driver findElement By xpath    div  class  infaCompositeViewTitle       String assets    String  js executeScript  return arguments 0  getElementsByTagName  span   1  textContent    ele     In this example  I have following HTML fragment and I am reading  156     lt div class  infaCompositeViewTitle  gt      lt span gt All Assets lt  span gt      lt span gt 156 lt  span gt   lt  div gt

Based on your previous questions  I suppose you want to run JavaScript snippets from Java s WebDriver  Please correct me if I m wrong   The WebDriverJs is actually  just  another WebDriver language binding  you can write your tests in Java  C   Ruby  Python  JS and possibly even more languages as of now   This one  particularly  is JavaScript  and allows you therefore to write tests in JavaScript   If you want to run JavaScript code in Java WebDriver  do this instead   WebDriver driver   new AnyDriverYouWant    if  driver instanceof JavascriptExecutor          JavascriptExecutor driver  executeScript  yourScript         else       throw new IllegalStateException  This driver does not support JavaScript         I like to do this  also   WebDriver driver   new AnyDriverYouWant    JavascriptExecutor js  if  driver instanceof JavascriptExecutor        js    JavascriptExecutor driver       else throw        later on    js executeScript  return document getElementById  someId         You can find more documentation on this here  in the documenation  or  preferably  in the JavaDocs of JavascriptExecutor   The executeScript   takes function calls and raw JS  too  You can return a value from it and you can pass lots of complicated arguments to it  some random examples       returns the right WebElement    it s the same as driver findElement By id  someId    js executeScript  return document getElementById  someId           draws a border around WebElement WebElement element   driver findElement By anything  tada     js executeScript  arguments 0  style border  3px solid red    element       changes all input elements on the page to radio buttons js executeScript           var inputs   document getElementsByTagName  input                for var i   0  i  lt  inputs length  i                       inputs i  type    radio

You can also try clicking by JavaScript   WebElement button   driver findElement By id  someid     JavascriptExecutor jse    JavascriptExecutor driver  jse executeScript  arguments 0  click      button     Also you can use jquery  In worst cases  for stubborn pages it may be necessary to do clicks by custom EXE application  But try the obvious solutions first
