How to execute JavaScript using Selenium WebDriver

With Java Script we can access the DOM Properties. By doing so we can get the properties values of those objects.

Say i have a Div or a Span control like below:
<Div id="SampleDiv1">I am in Div</Div> or
<Span id="SampleSpan1">I am in Span</Div>

Here we have two solutions to get the value of the objects.

Solution 1: Use the getAttribute method.
This method is described in below location:
http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/WebElement.html#getAttribute%28java.lang.String%29

So for ex above, we can use like:
String sReturnText=driver.findElement(By.id("SampleSpan1")).getAttribute("innerHTML");
System.out.println(sReturnText);


Because in the above example we are trying to get text from the control we can directly use getText method like below:
String sReturnText=driver.findElement(By.id("SampleSpan1")).getText();
System.out.println(sReturnText);

Solution 2: We can get the DOM properties be JavaScript
There might be situations you will be needing to run the JavaScript in your automation. To do this/cover the example follow below steps:
String sJScript = "return document.getElementById('SampleSpan1').innerHTML;";
String sReturnText = (String) ((JavascriptExecutor) driver).executeScript(sJScript);
 System.out.println(sReturnText);
