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
141.创建具有某些属性的对象
var myObject = new Object();

for (var a in myObject)
{
// 显示 "The property 'name' is James",等等。
window.alert("The property '" + a + "' is " + myObject[a]);
}//

var a=23.2;
alert(a%1==1)//
144.新建日期型变量
var a = new Date(2000, 1, 1);

145.给类定义新的方法
function trim_1()
{
return this.replace(/(^\s*)|(\s*$)/g, "");
}
String.prototype.trim=trim_1;
alert('cindy'.trim());
146.定义一个将日期类型转化为字符串的方法
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();
