点击编辑按钮，执行方法：

<script>
function pop(n){
layer.open({
type: 2,
title: '编辑主机信息',
closeBtn: 1,
area: ['700px', '550px'],
shadeClose: true, //点击遮罩关闭
content: ['/linux_servers_edit?id='+n,],
end:function(){
  var handle_status = $("#handle_status").val();
  if ( handle_status == '1' ) {
   layer.msg('保存成功！',{
    icon: 1,
    time: 2000 //2秒关闭（如果不配置，默认是3秒）
   },function(){
    history.go(0);
   });
  } else if ( handle_status == '2' ) {
   layer.msg('修改失败！',{
    icon: 2,
    time: 2000 //2秒关闭（如果不配置，默认是3秒）
   },function(){
    history.go(0);
   });
  }
 }
});
}
</script>

--linux_server_edit编辑方法：

@login_required(login_url='/login')
