140.注意不能通过与 undefined 做比较来测试一个变量是否存在,虽然可以检查它的类型是否为“undefined”。在以
下的代码范例中,假设程序员想测试是否已经声明变量 x : // 这种方法不起作用 if (x == undefined) // 作某些操作 // 这个方法同样不起作用- 必须检查
// 字符串 "undefined" if (typeof(x) == undefined) // 作某些操作 // 这个方法有效 if (typeof(x) == "undefined") // 作某些操作

return this.getYear()+"-"+tmp1+"-"+tmp2; } Date.prototype.toLiteString=guoguo_date; alert(new Date().toLiteString())
147. pasta 是有四个参数的构造器,定义对象。 function pasta(grain, width, shape, hasEgg) { // 是用什么粮食做的? this.grain = grain;
// 多宽?(数值) this.width = width;
// 横截面形状?(字符串) this.shape = shape;
// 是否加蛋黄?(boolean) this.hasEgg = hasEgg;
//定义方法 this.toString=aa; } function aa() {
} //定义了对象构造器后,用 new 运算符创建对象实例。 var spaghetti = new pasta("wheat", 0.2, "circle", true); var linguine = new pasta("wheat", 0.3, "oval", true); //补充定义属性,spaghetti和linguine都将自动获得新的属性 pasta.prototype.foodgroup = "carbohydrates";
148.打印出错误原因 try { x = y // 产生错误。 } catch(e) { document.write(e.description) //打印 "'y' is undefined". }//
149.生成Excel文件并保存 var ExcelSheet; ExcelApp = new ActiveXObject("Excel.Application"); ExcelSheet = new ActiveXObject("Excel.Sheet"); //本代码启动创建对象的应用程序(在这种情况下,Microsoft Excel 工作表)。一旦对象被创建,就可以用定义的对
象变量在代码中引用它。 在下面的例子中,通过对象变量 ExcelSheet 访问新对象的属性和方法和其他 Excel 对象,
包括 Application 对象和 ActiveSheet.Cells 集合。 // 使 Excel 通过 Application 对象可见。 ExcelSheet.Application.Visible = true; // 将一些文本放置到表格的第一格中。 ExcelSheet.ActiveSheet.Cells(1,1).Value = "This is column A, row 1"; // 保存表格。 ExcelSheet.SaveAs("C:\\TEST.XLS"); // 用 Application 对象用 Quit 方法关闭 Excel。 ExcelSheet.Application.Quit();//
