LBound函数返回指定数组的最小下标。因此,阵列的LBound为零。
语法
LBound(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 smallest Subscript value of the given array is : " & LBound(arr)) ' For MultiDimension Arrays : Dim arr2(3,2) document.write( "The smallest Subscript of the first dimension of arr2 is : " & LBound(arr2,1) & "<br />") document.write( "The smallest Subscript of the Second dimension of arr2 is : " & LBound(arr2,2) & "<br />") </script> </body> </html>
当以上代码另存为.html并在Internet Explorer中执行时,将产生以下结果:
The smallest Subscript value of the given array is : 0 The smallest Subscript of the first dimension of arr2 is : 0 The smallest Subscript of the Second dimension of arr2 is : 0
