        //many code here
        if(someelse===undefined){
                           //if by click, do some code.
                           //if by page loading, do not run these code.
            alert('ok');//check if it works.
        }
    }
    $(document).ready(function() {
        var someelse = 1;
                  ABC();                   
    });
    $('#click').click(function() {
        ABC();
    });

Try this:

 function ABC(status) {
    //many codes here
    if(status==='click'){
        //if by click, do some code.
        //if by page loading, do not run these code.
        alert('ok');//check if it works.
    }
}
$(document).ready(function() {
    ABC('default');                   
});
$('#click').click(function() {
    ABC('click');
});
