<html>
<body>
<script language = "vbscript" type = "text/vbscript">
Dim NumArray(3)
NumArray(0) = "VBScript"
NumArray(1) = 1.05
NumArray(2) = 25
NumArray(3) = #23/04/2013#
Dim DynamicArray()
ReDim DynamicArray(9) ' Allocate storage space.
Erase NumArray ' Each element is reinitialized.
Erase DynamicArray ' Free memory used by array.
' All values would be erased.
Document.write("The value at Zeroth index of NumArray is " & NumArray(0) & "<br />")
Document.write("The value at First index of NumArray is " & NumArray(1) & "<br />")
Document.write("The value at Second index of NumArray is " & NumArray(2) & "<br />")
Document.write("The value at Third index of NumArray is " & NumArray(3) & "<br />")
</script>
</body>
</html>
当上述代码保存为 .HTML 并在 Internet Explorer 中执行时，会产生以下结果 −
The value at Zero index of NumArray is The value at First index of NumArray is The value at Second index of NumArray is The value at Third index of NumArray is
