UBound函数返回指定数组的最大下标。因此，此值对应于数组的大小。
语法
UBound(ArrayName[,dimension])
- ArrayName，一个必需参数。此参数对应于数组的名称。
- dimension，可选参数。这需要一个整数值，该值对应于数组的维数。如果为“ 1”，则返回第一维的下限；否则为0。如果为’2’，则返回第二维的下限，依此类推。
例
<!DOCTYPE html> <html> <body> <script language = "vbscript" type = "text/vbscript"> Dim arr(5) arr(0) = "1" 'Number as String arr(1) = "VBScript" 'String arr(2) = 100 'Number arr(3) = 2.45 'Decimal Number arr(4) = #10/07/2013# 'Date arr(5) = #12.45 PM# 'Time document.write("The Largest Subscript value of the given array is : " & UBound(arr)) ' For MultiDimension Arrays : Dim arr2(3,2) document.write( "The Largest Subscript of the first dimension of arr2 is : " & UBound(arr2,1) & "<br />") document.write( "The Largest Subscript of the Second dimension of arr2 is : " & UBound(arr2,2) & "<br />") </script> </body> </html>
将以上代码另存为.HTML并在Internet Explorer中执行后，它会产生以下结果：
The Largest Subscript value of the given array is : 5 The Largest Subscript of the first dimension of arr2 is : 3 The Largest Subscript of the Second dimension of arr2 is : 2
