Activex Event use in JavaScript

If you want to use Activex Event in JavaScript 

You commonly use JavaScript Event listener

1.  

<script type="text/javascript" for="ActiveXControl" event="LogOn()"></script>

2.   

var ctrl = document.getElementById("ActiveXControl");

ctrl.attachEvent('LogOn', ActiveXControl_LogOn);

function ActiveXControl_LogOn() {

        

}

3.   

var ctrl = document.getElementById("ActiveXControl");

ctrl.addEventListener('LogOn', ActiveXControl_LogOn, false);

function ActiveXControl_LogOn() {

        

}

This way can't use correctly alert method. you can see alert only in debug mode.

I think this situation is have a thread problem.

I suggest other way to use eventhandling

By use timer, This problem can be solved.

// make eventArray 

var eventArray = [];

// if event occured, when you add information to eventArray

eventArray.push(information);

// make Timer

setInterval(function () {

if (eventArray.length > 0) {

var information= eventArray.pop();

alert("information: " + information);

}

}, 100);

This method can be use alert method
