js实现切换Tab标签

function $1(ID) {
            return document.getElementById(ID)
        }
        function setTab(ID) {
            for (var i = 1; i <= 6; i++) {
                if (ID == i) {
                    $1('one' + i).blur();
                    $1("one" + i).className = "out";
                    $1("conteb" + i).style.display = "block";
                }
                else {
                    $1("one" + i).className = "in";
                    $1("conteb" + i).style.display = "none";
                }
            }
            return false;
        }
