Question

if I’m invoking the following functions on page load:

addOnload(checkHeaders_m1)
addOnload(checkHeaders_m2)
addOnload(checkHeaders_m3)
addOnload(checkHeaders_m4)
addOnload(checkHeaders_m5)

can I save myself some code by using a wildcard? something like:

addOnload(checkHeaders_m\*)

if your onload functions are global then they would exist on the window object:

for (var i = 1; i < 6; i++) {
    addOnload(window['checkHeaders_m' + i]);
}

Alternatively, make the functions properties of some other object so that you don’t pollute the global namespace:

var myObj = {
    checkHeaders_m1: function () { ... },
    checkHeaders_m2: function () { ... },
    checkHeaders_m3: function () { ... },
    checkHeaders_m4: function () { ... },
    checkHeaders_m5: function () { ... }
};

for (var i = 1; i < 6; i++) {
    addOnload(myObj['checkHeaders_m' + i]);
}
