实现隔行变色及鼠标滑过变色

function test(o, a, b, c, d, e, f, g) {
    var t = document.getElementById(o).getElementsByTagName("tr");
 
    for (var i = g - 1; i < t.length; i++) {
        t[i].style.backgroundColor = (t[i].sectionRowIndex % 2 == 0) ? a : b;
        t[i].onclick = function () {
            if (this.x != "1") {
                this.x = "1"; 

                this.style.backgroundColor = d;
            } else {
                this.x = "0";
                this.style.backgroundColor = (this.sectionRowIndex % 2 == 0) ? a : b;
            }
        }
        t[i].onmouseover = function () {
            if (this.x != "1") {
                this.style.backgroundColor = c;
                this.style.color = e;
            }
        }
        t[i].onmouseout = function () {
            if (this.x != "1") {
                this.style.backgroundColor = (this.sectionRowIndex % 2 == 0) ? a : b;
                this.style.color = f;
            }
        }
    }
}
