关于手动修改设置的一个问题

你的意思是这个意思吧！ <script language="javascript" type="text/javascript">
function update(){
  if(document.getElementById("checkbox").checked==true){
     document.getElementById("netmask").disabled="";
document.getElementById("gateway").disabled="";
document.getElementById("servername").disabled="";
document.getElementById("ip").disabled="";

  }else{
  document.getElementById("netmask").disabled="disabled";
  document.getElementById("gateway").disabled="disabled";
  document.getElementById("servername").disabled="disabled";
  document.getElementById("ip").disabled="disabled";
  }

}
</script>
