如何将一个页面中所有出现的IP地址文字转换成字符串 "XXX.XXX.XXX.XXX" 并显示出来？

ip="202.193.64.34";
tempip=ip.split(".");
for(var i=0;i<tempip.length;i++){
document.write(tempip[i]);
}

  1.   

    var ip="用户IP:202.193.64.34";
    var ipExp = /\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/gi;
    alert(ip.replace(ipExp,'XXX.XXX.XXX.XXX'));
      

  2.
