Question

numba = 1;

function A() {
    numba++;
    console.log(numba);
}

$(function() {
    var numnum2 = 0;
    setInterval('A()',1000);
    //setInterval(B.apply($(this)), 1000);
});


function B() {
    $(this).numnum2++;
    console.log($(this).numnum2);
}

Fiddle

How can I get B() to function as A() minus the global variable?

Answer 1

$(function() {
    var numnum2 = 0;

    function B() {
        numnum2++;
        console.log(numnum2);
    }

    setInterval(A,1000);
    setInterval(B,1000);
});

or

function B() {
    if(typeof B.numnum2 === 'undefined') B.numnum2 = 0;
    B.numnum2++;
    console.log(B.numnum2);
}

$(function() {
    B.numnum2 = 0;
    setInterval(A, 1000);
    setInterval(B, 1000);
});
