140.注意不能通過與 undefined 做比較來測試一個變量是否存在,雖然可以檢查它的類型是否為“undefined”。在以
下的代碼范例中,假設程序員想測試是否已經聲明變量 x :
// 這種方法不起作用
if (x == undefined)
// 作某些操作
// 這個方法同樣不起作用- 必須檢查
// 字符串 "undefined"
if (typeof(x) == undefined)
// 作某些操作
// 這個方法有效
if (typeof(x) == "undefined")
// 作某些操作
141.創建具有某些屬性的對象
var myObject = new Object();
myObject.name = "James";
myObject.age = "22";
myObject.phone = "555 1234";//
142.枚舉(循環)對象的所有屬性

145.給類定義新的方法
function trim_1()
{
return this.replace(/(^\s*)|(\s*$)/g, "");
}
String.prototype.trim=trim_1;
alert('cindy'.trim());
146.定義一個將日期類型轉化為字符串的方法
function guoguo_date()
{
var tmp1,tmp2;
tmp1 =this.getMonth()+1+"";
if(tmp1.length<2)
tmp1="0"+tmp1;
tmp2 =this.getDate()+"";
if(tmp2.length<2)
tmp2="0"+tmp2;
return this.getYear()+"-"+tmp1+"-"+tmp2;
}
Date.prototype.toLiteString=guoguo_date;
alert(new Date().toLiteString())
147. pasta 是有四個參數的構造器,定義對象。
function pasta(grain, width, shape, hasEgg)
{
// 是用什麼糧食做的?
this.grain = grain;
// 多寬?(數值)
this.width = width;
// 橫截面形狀?(字符串)
this.shape = shape;
// 是否加蛋黃?(boolean)
this.hasEgg = hasEgg;
//定義方法
this.toString=aa;
}
function aa()
{
}
//定義了對象構造器後,用 new 運算符創建對象實例。
var spaghetti = new pasta("wheat", 0.2, "circle", true);
var linguine = new pasta("wheat", 0.3, "oval", true);
//補充定義屬性,spaghetti和linguine都將自動獲得新的屬性
pasta.prototype.foodgroup = "carbohydrates";
148.打印出錯誤原因
try
{
x = y // 產生錯誤。
}
catch(e)
{
document.write(e.description) //打印 "'y' is undefined".
}//
149.生成Excel文件並保存
var ExcelSheet;
ExcelApp = new ActiveXObject("Excel.Application");
ExcelSheet = new ActiveXObject("Excel.Sheet");
//本代碼啟動創建對象的應用程序(在這種情況下,Microsoft Excel 工作表)。一旦對象被創建,就可以用定義的對
象變量在代碼中引用它。 在下面的例子中,通過對象變量 ExcelSheet 訪問新對象的屬性和方法和其他 Excel 對象,
包括 Application 對象和 ActiveSheet.Cells 集合。
// 使 Excel 通過 Application 對象可見。
ExcelSheet.Application.Visible = true;
// 將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 對象用 Quit 方法關閉 Excel。
ExcelSheet.Application.Quit();//
