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

You can also use eval() to do the same thing.

//A function to call
function needToBeCalled(p1, p2)
{
    alert(p1+"="+p2);
}

//A function where needToBeCalled passed as an argument with necessary params
//Here params is comma separated string
function callAnotherFunction(aFunction, params)
{
    eval(aFunction + "("+params+")");
}

//A function Call
callAnotherFunction("needToBeCalled", "10,20");

That's it. I was also looking for this solution and tried solutions provided in other answers but finally got it work from above example.
