 Deploying WebRenderer in a Java Applet

WebRenderer has two effective methods used for communicating between Java and JavaScript code. The methods available consist of the executeScript method and the executeScriptWithReturn method found in IBrowserCanvas.

executeScript: - executeScript takes a String containg any valid JavaScript which will be immediately executed on the page loaded in WebRenderer. Using this method you can directly call global or custom JavaScript functions.

Example:
//Changing the current documents background color to green
browser.executeScript("document.body.style.backgroundColor='green';");
//Throwing a JavaScript Alert dialog box
browser.executeScript("alert('Background color changed');");

executeScriptWithReturn: - executeScriptWithReturn returns any variable from JavaScript or method return values that you choose to call it upon.

Example:
//Executing some JavaScript - Calling a function in JavaScript that
//has a return value and passing the return value back to Java.
System.out.println(browser.executeScriptWithReturn("document.title"));

The executeScriptWithReturn can be called on any JavaScript function or variable and it will return the value.
