How can I execute JavaScript code within Java's Selenium WebDriver?

Using JavaScript with Selenium WebDriver Java

You are interested in utilizing JavaScript with WebDriver (Selenium 2) through Java.

Command Execution Location

The command you referred to, "$ ./go webdriverjs," should be executed from the directory where the WebDriverJs project is located.

Integrating JavaScript into WebDriver

However, note that WebDriverJs is a separate language binding for WebDriver, allowing test creation in JavaScript. To execute JavaScript within Java's WebDriver, follow these steps:

<code class="java">WebDriver driver = new AnyDriverYouWant();
if (driver instanceof JavascriptExecutor) {
    ((JavascriptExecutor)driver).executeScript("yourScript();");
} else {
    throw new IllegalStateException("This driver does not support JavaScript!");
}</code>

Copy after login

Alternatively:

<code class="java">WebDriver driver = new AnyDriverYouWant();
JavascriptExecutor js;
if (driver instanceof JavascriptExecutor) {
    js = (JavascriptExecutor)driver;
} // else throw...

// later on...
js.executeScript("return document.getElementById('someId');");</code>

Copy after login

The executeScript() method accepts both function calls and plain JavaScript code. It offers the capability to return values and pass complex arguments, as demonstrated in these examples:

Return a WebElement:

<code class="java">js.executeScript("return document.getElementById('someId');");</code>

Copy after login

Add a border to a WebElement:

<code class="java">WebElement element = driver.findElement(By.anything("tada"));
js.executeScript("arguments[0].style.border='3px solid red'", element);</code>

Copy after login

Change input elements to radio buttons:

<code class="java">js.executeScript(
         "var inputs = document.getElementsByTagName('input');" +
         "for(var i = 0; i &lt; inputs.length; i++) { " +
         "    inputs[i].type = 'radio';" +
         "}" );</code>
