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
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 & objImageFileToUse.Name
Set objImageFileToUse = Nothing
以下是引用片段:
#pic{
width: 400px;
height: 300px;
background: url(<%= strImageSrcText %>) no-repeat;
margin: 2em auto;
}
上面代码要加在header区,不能放在外部CSS文件里。
