I am working on a chatting app that makes use of flash sockets. I don’t want to code the entire interface in flash, so I was hoping to just use flash to talk to the socketserver and call js to modify the dom.

can this be done?

    To call a JavaScript function from Flash, use the ExternalInterface.call function in ActionScript:

    import flash.external.ExternalInterface;

// Call a JavaScript function
ExternalInterface.call("your_javascript_function");

// Get a return value from a JavaScript function
var x:int = ExternalInterface.call("get_x");

// Pass an argument to a JavaScript function
var retval:int = ExternalInterface.call("some_js_function", "the-argument");

    To call an ActionScript function from JavaScript, first use the ExternalInterface.addCallback function in ActionScript:

    // "methodName" is the method to call in JavaScript
// instanceObject.realMethod is the method that will be triggered
var successful = ExternalInterface.addCallback("methodName",
                                               instanceObject,
                                               realMethod);

    Then, get a handle on the SWFObject in JavaScript and call the ActionScript method as follows:

    function makeActionScriptCall() {
    var flash = document.getElementById(movieName);
    flash.methodName(parametersIfAny);
}
