Javascript 为什么不是'；难道我的数据没有被添加到Mojolicous的仓库里吗？

我对Mojolicious和藏品有意见，我想我可能只是不理解它的工作方式？ 我有一个带有2个组合框的页面，当第一个条目发生变化时，我希望更新第二个条目中的选项

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

因此，我添加了一个如下所示的事件处理程序，它调用我的控制器子例程“devicecommandset”，然后将DBIx查询的结果放入一个哈希数组中，并将其添加到我的存储库中

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

然后我只是呈现一些良性文本。我的子例程被调用，并且在“@commandset”中有预期的内容。但是，我无法在浏览器控制台的隐藏中看到它（我正在调试模式下运行）

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

我真的需要修改DOM来填充隐藏吗？基本上，我只是试图从我的请求中获取数据，以填充组合框选项

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

在我的模板中

$(document).ready(function() {

 $('select:not([name*="command"])').live('change', function (e) {
     $.get('devicecommandset', { device: $(this).attr("value") },
          function (data) {
                alert("Made it this far");
           });
      });         
 });

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

在我的控制器中

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

您基本上是在日志中打印转储程序，而不是在浏览器中。您的隐藏未在渲染中使用，因为您没有引用它。使用内联渲染类型和“转储程序”辅助程序。 尝试：

sub devicecommandset {
  my $self = shift;
  my $device = $self->param('device') || '';
  my @commandsets = $self->db->resultset('CommandSet')->search_commandsets_by_devicename($device); 
  $self->stash(commandsets => \@commandsets );
  print Dumper(@commandsets);
  $self->render(text => 'success' );
 }

$self->stash（commandset=>\@commandset）；
$self->render（内联=>''；
