When the subroutine is executed CISimgSrc is shown with the value selected in pickImage. This sets up the two options with id pickImage. OnServerClick I will execute the subroutine called choose_image. Initially the right side image (CISa.gif) is shown. <html> <head><title>Flip image</title> <script runat="server"> Sub choose_image(Sender As Object, e As EventArgs) CISimg.Src = pickImage.Value End Sub </script> </head> <body> <form runat="server"> <select id="pickImage" runat="server"> <option value="CISa.gif">Right side up</option> <option value="CISb.gif">Upside down</option> </select> <input type="submit" runat="server" value="Display image" OnServerClick="choose_image"> <br /><br /> <img id="CISimg" src="CISa.gif" runat="server" /> </form> </body> </html> |

This code sets up two radio buttons to use to determine whether youwant to see the image right side up or upside down. When executed the subroutine checks to see if the first button with id=right is checked if so the image is displayed right side up, else it is displayed upside down. <html> <head><title>Flip image</title> <script runat="server"> Sub choose_image(Sender As Object, e As EventArgs) If right.Checked=True then CISimg.Src = "CISa.gif" else CISimg.Src = "CISb.gif" end if End Sub </script> </head> <body> <form runat="server"> <input id="right" name="flip" type="radio" runat="server">Right side up</input> <br /> <input id="upside" name="flip" type="radio" runat="server">Upside down</input> <input type="button" runat="server" value="Display image" OnServerClick="choose_image"> <br /><br /> <img id="CISimg" src="CISa.gif" runat="server" /> </form> </body> </html> |
