随机背景--当你每次进入该页面时,从已指定的图片文件夹中,随机选取一个图片作为背景显示。这里介绍的方法是用ASP CSS来实现的。
ASP
以下是引用片段:Const IMGS_DIR = "/images"
'设定图片文件夹的地址,随机显示该文件夹内任一张图片
以下为引用的内容:
Dim objFSO, objFolderObject, objFileCollection, objFile Dim intFileNumberToUse, intFileLooper Dim objImageFileToUse Dim strImageSrcText Set objFSO = Server.CreateObject("Scripting.FileSystemObject") Set objFolderObject = objFSO.GetFolder(Server.MapPath(IMGS_DIR)) Set objFSO = Nothing Set objFileCollection = objFolderObject.Files Set objFolderObject = Nothing Randomize() intFileNumberToUse = Int(objFileCollection.Count * Rnd) 1 intFileLooper = 1 For Each objFile in objFileCollection If intFileLooper = intFileNumberToUse Then Set objImageFileToUse = objFile Exit For End If intFileLooper = intFileLooper 1 Next Set objFileCollection = Nothing strImageSrcText = IMGS_DIR
