Communicating from JavaScript back to Java

The WebRenderer WRUIprotocol allows for communication from JavaScript to Java. Using the WRUI protocol you can directly communicate with Java and with some simple handler code you can drive methods, assign variables etc.

Example: (HTML file with JavaScript calling through to Java when an HTML Button is clicked)

                <HTML>
                <SCRIPT JAVASCRIPT>
                                function runJavaCode(){
                                                document.location = "wrui://runConsoleOutput";
                                }
                </SCRIPT>

                <HEAD><TITLE>WebRenderer - WRUI Test Page</TITLE></HEAD>
                <BODY>
                <BR>
                Press this button <INPUT type=button value='Click to execute' onclick='runJavaCode()'> execute                 JavaScript that will call a Java function
                </BODY>
                </HTML>

// Java
                 browser.addBrowserListener(new BrowserAdapter(){
                        public void onBeforeNavigate(BrowserEvent e){
                                //Catching the WRUI communication
                                if(e.getURL().equals("wrui://runConsoleOutput/")){
                                        //Calling a Java method using WRUI as a communication bridge
                                        runConsoleOutput();
                                }
                        }
                });
