❶ 网页设计:如何用JS定义一个数组存放成绩并把数组里的成绩相加并求平均分

function GRADE(arr){this._arr = typeof(arr) == "string" ? arr.split(",") : arr;}
GRADE.prototype.totalGrade = function(){var ret = 0;for (var i=0; i<this._arr.length; i++){ret = ret + parseFloat(this._arr[i]);}return ret;}
GRADE.prototype.average = function(){return this.totalGrade()/this._arr.length}

var grade = new GRADE([1,2,3,4,5]);
//也可以传一个字符串 var grade = new GRADE("1,2,3,4,5")
document.write("总分：" + grade.totalGrade());
document.write("<br />");
document.write("平均分：" + grade.average());

❷ 如何用JS脚本协助web网页测试

试试来下自面这个方法：
public List<Bars> pageListTwo(int currentPage, int showRows)

Connection con = null;
PreparedStatement ps = null;
ResultSet rs = null;
ArrayList<Bars> resultList = new ArrayList<Bars>();
try
{
