Question

I’m trying to call a function from inside the call of another function.

If I do it like this, it works fine. This returns ‘x’:

function returnval() {
    return ("x");
}

alert(
    returnval();
)

But how can I do the same thing while declaring the returnval function inside the function call? I’ve tried this, and everything else I could think of, to no avail. It returns ‘function(){return(“x”);})’ instead of the value itself, ‘x’:

alert(
    function() {
        return ("x");
    }
)

In a similar vein, I’d like to include if-statements in function calls as well. Is this at all possible?

Any help would be appreciated. 🙂

There’s a thing, called like instant function call. You call a function just after a declaration:

(function() {
    // ... function body
})()
