The code is as follows:
Var thisImgNo = 290
Function ajaxConn () {
Var xmlhttp = false
Try {xmlhttp = new ActiveXObject ("Msxml2.XMLHTTP");}
Catch (e) {try {xmlhttp = new ActiveXObject ("Microsoft.XMLHTTP");}
Catch (e) {try {xmlhttp = new XMLHttpRequest ();}
Catch (e) {alert (e); xmlhttp = false;}}
If (! xmlhttp) return null
This.connect = function (Url,Method,postContent) {
If (! xmlhttp) return false
Method = Method.toUpperCase ()
Try {
If (Method = = "GET") {
Xmlhttp.open (Method,Url +'?'+ postContent,true)
Xmlhttp.setRequestHeader ("Content-Type", "text/html;charset=GB2312")
SVars = null
} else {
Xmlhttp.open (Method,Url,true)
Xmlhttp.setRequestHeader ("Method", "POST" + Url+ "HTTP/1.1")
Xmlhttp.setRequestHeader ("Content-Type", "application/x-www-form-urlencoded")
}
Xmlhttp.onreadystatechange = function () {
If (xmlhttp.readyState = = 4) {
If (xmlhttp.status = = 200) {
ImgInfo = xmlhttp.ResponseText
Var imgInfoArr = imgInfo.split ("|")
Var tmpimg = new Image ()
Tmpimg.src = imgInfoArr [0]
ThisImgNo = imgInfoArr [1]
Var element = document.getElementById ("img")
If (! element.xpos) element.xpos = 0
Element.style.width = (element.clientWidth + 130) + "px"
SlideElement ("img", element.xpos-130,0,10)
Element [XSS _ clean] + ='
'
}
}
}
Xmlhttp.send (postContent)
} catch (z) {return false;}
Return true
}
Return this
}
Function loadImg (type) {
Var element = document.getElementById ("img")
If (! element.xpos) element.xpos = 0
If (type== "pre") {
If (element.xpos==0) return false
SlideElement ("img", element.xpos+130,0,10)
} else {
If (element.xpos==- (element.clientWidth-260)) {
Var myConn = new ajaxConn ()
If (! myConn) return false
MyConn.connect ("Cmd.asp", "get", "d =" + thisImgNo)
} else {

}
}
}
Function slideElement (elementId,x,y,inc) {
Var element = document.getElementById (elementId)
If (element.sliding) clearTimeout (element.sliding)
If (! element.xpos) element.xpos = 0
If (! element.ypos) element.ypos = 0
If (element.xpos = = x & & element.ypos = = y) return true
If (element.xpos > x) {
Var dist = Math.ceil ((element.xpos-x) / inc)
Element.xpos = element.xpos-dist
}
If (element.xpos
< x) { var dist = Math.ceil((x-element.xpos)/inc); element.xpos = element.xpos + dist; } if(element.ypos >Y) {
Var dist = Math.ceil ((element.ypos-y) / inc)
Element.ypos = element.ypos-dist
}
If (element.ypos < y) {
Var dist = Math.ceil ((y-element.ypos) / inc)
Element.ypos = element.ypos + dist
}
Element.style.left = element.xpos+'px'
Element.style.top = element.ypos+'px'
Element.sliding = setTimeout ('slideElement ("' + elementId+'",'+ x-ray), 10)
}
