Pass a JavaScript function as parameter

Question

How do I pass a function as a parameter without the function executing in the \"parent\" function or using eval()? (Since I\'ve read that it\'s insecure.)

Answer 1

There is a phrase amongst JavaScript programmers: "Eval is Evil" so try to avoid it at all costs!

In addition to Steve Fenton's answer, you can also pass functions directly.

function addContact(entity, refreshFn) {
    refreshFn();
}

function callAddContact() {
    addContact("entity", function() { DoThis(); });
}
