How do I call a function defined in a javascript variable

I have a function defined in a javascript variable. How do I call that function within a javascript function?

function clear_viewer() {
     var stop_function = "jwplayer.stop();";
     // call stop_function here
}

Thanks.

Could always go with the 'all evil' eval():

eval(stop_function);

Obviously you need to be very careful when using eval so that you don't wind up executing malicious code accidentally. Another option would be to turn stop_function into an anonymous function that executes your code:

var stop_function = function(){
    jwplayer.stop();
};

stop_function();

function clear_viewer() {
     var stop_function = "jwplayer.stop();";
     eval(stop_function);
}

You shouldn't do this though, eval should be avoided if at all possible. Instead you should do something more like this, which creates a function directly for later execution.

function clear_viewer() {
     var stop_function = function() {
       jwplayer.stop();
     };
     stop_function();
}
