How to suppress quotes output as HTML entities?

Question

$selected = ' selected="selected"'
# or
$selected = qq( selected="selected")

is returned as:

selected="selected"

which is an invalid HTML attribute, ofcourse.

How do I fix it?

Edited to add:

<select name="alignment" class="select" 
    <%== param('feature') ? '' : 'disabled'; %>
>
% foreach (keys %al) {
%  my $selected = param('aligment') && param('aligment') eq $_ ? ' selected' : '';
%
%  if (!param('aligment') && $_ eq 'left') { $selected = ' selected' }
%
    <option value="<%=$_%>" <%= $selected %>>
     <%= $al{$_} %>
    </option>
%        
% }
</select>

Thanks!

根据Mojolicious Web框架文档,您需要添加和extra = at <%=才能以原始格式打印它.

<%= $selected %>

将会

<%== $selected %>

试试这样:

<select name="alignment" class="select" 
    <%== param('feature') ? '' : 'disabled'; %>
>
% foreach (keys %al) {
%  my $selected = param('aligment') && param('aligment') eq $_ ? ' selected' : '';
%
%  if (!param('aligment') && $_ eq 'left') { $selected = ' selected' }
%
<option value="<%=$_%>"
 <%= $selected %>
>
     <%= $al{$_} %>
    </option>
%        
% }
</select>

要么

<select name="alignment" class="select" 
    <%== param('feature') ? '' : 'disabled'; %>
>
% foreach (keys %al) {
%  my $selected = param('aligment') && param('aligment') eq $_ ? ' selected="selected"' : '';
%
%  if (!param('aligment') && $_ eq 'left') { $selected = ' selected="selected"' }
%
<option value="<%=$_%>"
 <%== $selected %>
>
     <%= $al{$_} %>
    </option>
%        
% }
</select>
