<script type="text/javascript">
    function B()
    {
        alert('2');
        A();
    }

    function A()
    {
        alert('1');
        B();
    }
</script>

<html>
<body onload="A();">
</body>
</html>

Is it possible to use javascript to do that without jQuery? In my script, A can call B, but B can’t call A? I don’t know why B can’t call A in my script. I’m not sure that is because A hasn’t finished so that B can’t call A right now. A>B>A>B>A>B makes an infinte loop. Can I do the above result in some way?

    use setTimeout or setInterval functions. they’r working asynchronously. 

    function B()
{
    alert('2');
    setTimeout(A, 1);
    alert('3');
}

function A()
{
    alert('1');
    setTimeout(B, 1);
}

    in function B javascript will wait for 1 millisecond and call function A, but it will also continue executing your code in B so ‘3’ will be alerted and B will be ended before calling A
