                 {
                    document.getElementById("movie"+i).sndToAS("resume");
                 }
             }

         }
         function action()
         {
            document.getElementById("movie0").sndToAS("pause");
         }
         function action2()
         {
            if(tmp != "movie0")
            {
                document.getElementById("movie0").sndToAS("pause");

            }
         }

Actually I am using JS for communicationg with flash audio and video players. My code little bit larger. I wants to know is there any Listener like addEventListener and removeEventListener?. — Benny

What is the need for elaborate??? I know how to deactivate the functions and I don't know how to reactivate the functions. This code is enough for that. — Benny

Do something like this

function actionFunc(){
    document.getElementById("movie0").sndToAS("pause");
}
function action2Func()
{
    if(tmp != "movie0"){
     document.getElementById("movie0").sndToAS("pause");

    }
}

window.action = actionFunc;
window.action2 = action2Func;

if(tmpStr == tmp+value)
{
    id=1;
    window.action = null;
    window.action2 = null;
}
if(tmpStr1 == tmp+value)
{
    id=0;
    window.action = actionFunc;
    window.action2 = action2Func;
}

Then when you want to call your functions all you have to do is

action();
action2();

but your going to want to check if the are set before calling them

I believe thats what your after

or do something like this

function action(){
    if (window.actionEnabled)
    {
       document.getElementById("movie0").sndToAS("pause");
    }
}
function action2()
{
    if (window.action2Enabled)
    {
       if(tmp != "movie0"){
         document.getElementById("movie0").sndToAS("pause");
       }
    }
}

window.actionEnabled = true;
window.action2Enabled = true;

if(tmpStr == tmp+value)
{
    id=1;
    window.actionEnabled = false;
    window.action2Enabled = false;
}
if(tmpStr1 == tmp+value)
{
    id=0;
    window.actionEnabled = true;
    window.action2Enabled = true;
}

then you don't have to check if the are enabled just call them and they will work or want depending on if they are enabled

If you don't want a function to execute when in a particular state, I would wrap your function do a state check and then a return if in an inappropriate state.

function action(obj){
   if(obj.state == <a state you dont want to execute>)
     return;

   action();
} 

function action(){
   document.getElementById("movie0").sndToAS("pause");
}

just declare a global variable

var stopfunction=false;

and as a first line in your function

if (stopfunction) return;
