How to use an argument from one function to call another function

I'm trying to figure out how to pass an argument to one function, which is actually a second function. Hard to explain so here is some sample code:

keyDownEvent("#thisID",nameOfFunctionToRunOnOpen);

function keyDownEvent(id, openFunction) {
$(id).dialog( {
    close: focusOnInput(),
    open: nameOfFunctionToRunOnOpen,
    modal: true,
    show: "clip",
    hide: "fade"
});
}

Everything else is standard for my .dialog() calls, just want to modify what happens on Open. Any idea how this can be achieved?

You can simply pass the function to your second function. Functions are objects in JavaScript and can be saved in variables:

function outer(someOtherFunction) {
    someOtherFunction();
}

outer(function () {
    alert('inner function');
});

Just use an anonymous function:

function keyDownEvent(id, openFunction) {
$(id).dialog( {
    close: focusOnInput(),
    open: function(){openFunction(someArgument);},
    modal: true,
    show: "clip",
    hide: "fade"
});
}

Your second parameter should be given an actual function object and not just the name of the function in a string.
