//要实现获得一个maxNumber到minNumber范围内的随机整数，实现方法如下：
//       choNumber=maxNumber-minNumber+1;
//       number=Math.floor(Math.random()*choNumber+minNumber)

var numTemp = Math.floor(Math.random() * 7);   //实例产生了一个0-6的随机数
if(!numTemp)
	numTemp=1;
var numStr = String(numTemp);
if (numStr.length == 1)
    numStr = "0" + numStr;
var url_BGImage = "url(/Templets/BGimages/Head_BG" + numStr + ".jpg)";
var bgImageID=document.getElementById("Header_Container_Banner");
if (bgImageID) {
    bgImageID.style.backgroundImage = url_BGImage;
}
