Oracle Forms

Hi,

i want to achieve forms js communication (html menu). So when user click i pass the name of the link form. This code work fine in ie :

var x = document.getElementById("testjs");
var y = x.contentWindow.document;
y.forms_frame.raiseEvent('call_form',form.nom.toLowerCase());}

this work fine with IE11 but i want to use it with firefox esr 52.9 and google chrome 43. Both support applet

i add this function(found in the net)  to my js like this:

 function raiseEvent(element, eventName, eventDetails) {
        var event;
        var bubbles = true;
        var cancelable = false;
        try {
            event = new CustomEvent(eventName, {
                bubbles: bubbles,
                cancelable: cancelable,
                detail: eventDetails
            });
        } catch (e) {
            event = document.createEvent("CustomEvent");
            event.initCustomEvent(eventName, bubbles, cancelable, eventDetails);
        }
        element.dispatchEvent(event);
    }

so my code becomes:

raiseEvent(y.forms_frame,'call_form',form.nom.toLowerCase());

in firefox or ie theres no error in javascript console but nothing happen.

how can i dispatch the event like with the IE raiseEvent.

regards

Walid
