帮助用户快速实现各种应用服务,ASP商有整合各方面资源的能力,可在短期内为用户提供所需的解决方案。例如,典型的ERP安装,如果要在客户端安装的话需要半年到二年的时间,但是美国的一些ASP商如USI和CORIO能在90—120天内提供ERP应用方案。ip地址 <script language="JScript" Runat="Server">
function IPDeCode(EIP){
var Ip1,Ip2,Ip3,Ip4;
Ip1 = moveByteR(EIP & 0xff000000,3);
Ip2 = moveByteR(EIP & 0x00ff0000,2);
Ip3 = moveByteR(EIP & 0x0000ff00,1);
Ip4 = EIP & 0x000000ff;
return Ip1 + "." + Ip2 + "." + Ip3 + "." + Ip4;
}
function moveByteL(num,bytenum){
return num <<= (bytenum*8)
}
function moveByteR(num,bytenum){
return num >>>= (bytenum*8)
}
</script>
在vbs中没有位操作,如许在一个页面顶用到了js和vbs,其实不好,假如用vbs也能够,不外罗嗦了一些,并且有一点注重,假如在vbs中split("202.102.29.6",","),会失掉202,102,29三个数,得不到最初一个6,所以需求将ip换成split("202.102.29.6" & ".",",")
我用vbs做的,因为没有位操作,所以做得对照费事

function ip2int(ipstr)
dim iptemp,max

exit function

a = "&H"
for i = 0 to 3
b = Hex(iptemp(i))
if len(b) = 1 then
b = "0"&b

a = a&b
next
ip2int = CLng(a)

function int2ip(ip)
dim iptemp,a,ipstr,i,length
iptemp = Hex(ip)
length = 8 - len(iptemp)

response.write testIP & " will be dencoded to <font color=red>" & int2ip(testInt) & "</font><br>"
