str=str.toLowerCase();//str="abcd"


擷取IP Address

function iptrans()

{

//  十進位轉16進位

//function d2h(d) {return d.toString(16);}

  IPstr=document.GE_MgrFrm.IPaddress.value;

  var datePart = IPstr.match(/(\d{1,3}).(\d{1,3}).(\d{1,3}).(\d{1,3})/);

  p1=parseInt(datePart[2],10).toString(16);

  p2=parseInt(datePart[3],10).toString(16);

  p3=parseInt(datePart[4],10).toString(16);

  if (parseInt(datePart[3],10) < 16)

    p1='0' + p1;

  if (parseInt(datePart[3],10) < 16)

    p2='0' + p2;

  if (parseInt(datePart[3],10) < 16)

    p3='0' + p3;

  document.GE_MgrFrm.Resultaddress.value = '01:00:5E:'+ p1.toUpperCase() +':'+ p2.toUpperCase() +':'+ p3.toUpperCase();

}

擷取MacAddress

function mactrans()

{

//16進位轉十進位

//function h2d(h) {return parseInt(h,16);}

  MACstr=document.GE_MgrFrm.MACaddress.value;

  //var datePart = MACstr.match(/([0-9a-f]{2})[:-]([0-9a-f]{2})[:-]([0-9a-f]{2})[:-]([0-9a-f]{2})[:-]([0-9a-f]{2})[:-]([0-9a-f]{2})/i);

  var datePart = MACstr.match(/([0-9a-f]{1,2})[:-]([0-9a-f]{1,2})[:-]([0-9a-f]{1,2})[:-]([0-9a-f]{1,2})[:-]([0-9a-f]{1,2})[:-]([0-9a-f]{1,2})/i);

  document.GE_MgrFrm.Resultaddress.value = '224.' + parseInt(datePart[4],16) +'.'+ parseInt(datePart[5],16) +'.'+ parseInt(datePart[6],16);
