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

I suggest to put the parameters in an array, and then split them up using the .apply() function. So now we can easily pass a function with lots of parameters and execute it in a simple way.

function addContact(parameters, refreshCallback) {
    refreshCallback.apply(this, parameters);
}

function refreshContactList(int, int, string) {
    alert(int + int);
    console.log(string);
}

addContact([1,2,"str"], refreshContactList); //parameters should be putted in an array
