// 1) create a 88*31 LOGO.
If (document. images)
Var staticlogo = new Image (758,100)
// 2) set the LOGO path.
Staticlogo. src = "/images/banner.gif"
// 3) The following is the link represented by the LOGO.
Var logolink = "http://wwwww.jb51.net /"
// 4) set the ALT attribute.
Var alttext = "code home"
// 5) set the following attributes to 1 or 0 (1 is unique to IE to hide the LOGO)
Var fadeappsview = 1
/* 6) finally set the LOGO display time, for example, 12 seconds. The value 0 indicates that the LOGO is always displayed.
*/
Var visibleduration = 5
Function regenerate (){
Window. location. reload ()
}
Function regenerate2 (){
If (document. layers)
SetTimeout ("window. onresize= regenerate", 400)
}

Document. write ('<span id = "logo" "style ="' + fadeset + '; position: absolute; top: 100; width:' + staticlogo. width + '; height:' + staticlogo. height + '"> </span> ')
Function bringlateral view (){
If (logo. filters. alpha. opacity <= 95)
Logo. filters. alpha. opacity + = 5
Else {
ClearInterval (viewit)
If (visibleduration! = 0)
SetTimeout ("logo. style. visibility = 'den den '", visibleduration * 1000)
