If you do an <input type=number>, most newer browsers will restrict values to numeric, mobile browsers will pop up a numeric keypad, and old browsers will just do a normal text field because they don't recognize that type (and the default is plain text). You can't rely on that (always verify on the server side), and the ui_lib doesn't create these for you, but giving some feedback on the client side this way is almost free, so it's basically win-win. :)

[webmin-devel] Log access

Emma wasanzy — 2013-03-26T20:11:07

Hello,

As part of the module I am writing for tomcat management, I wrote a module
for accessing tomcat logs.

The problem I have is, when I open the page, the default selected fields
should cause the logs to display in the textarea box but this is not so. I
have to click on the "Display" button before the logs get displayed. The
second problem is that, when I select new fields and click on displays, the
logs displays alright but the fields changed back to the default fields
which in normal sense shouldn't be so.

Here is the code below:

 #!/usr/bin/perl

require 'tomcat-lib.pl';
#&ReadParse();
&ui_print_header(undef, $text{'logaccess_title'}, "", "tomcatlog");

#Get all instances
< at >insts = File::Slurp::read_file( $config{'tomcat_instance'} ) or die
"Failed to read $config{'tomcat_instance'} - $!";


#Log type: access or catalina.out
< at >log_types = ( "catalina.out", "access_log" );

$in{'inst'} =~ s/\s+//;

$in{'inst'} ||= $insts[0];
&indexof($in{'inst'}, < at >insts) >= 0 || &error( $text{'no_log'} );

Re: [webmin-devel] Strict

   Actually, "use strict" should work just fine - a while back I updated the
   core Webmin API to use strict and warnings modes, and all new modules have
   been written to turn those on.
   For example, see the module in the "webmin" subdirectory for how this is
   done.

What Jamie built, for those of you who have taken the time to really consider it, is a monumental achievement and contribution to system administrators all over the world.  I’m not “polishing apples” here.  I owe countless hours “recovered” through the use of Webmin to the guy.

Re: [webmin-devel] Strict

Chris Nighswonger — 2013-03-22T14:54:44

I'm sure only the webmin developer knows why he did not use strict,
however, you can still use it. Just initialize vars you intend on importing
thus:

#!/usr/bin/perl

our( %in, %text, %config );

use strict;
use warnings;

etc.....

Older Perl did not support the 'our' pragma, but 'vars.' [1] So keep that
in mind if you are using an older Perl.

Kind Regards,
Chris

Yea the same thing I did by removing the strict. When you look at webmin

Re: [webmin-devel] Strict

PEOPLES, MICHAEL P — 2013-03-22T13:38:46

It's not the API that is doing that, it's Perl's interpretation of the code (perhaps that's self-evident).  I have limited Perl knowledge and will defer to others on this.  However, I experienced the same thing when developing my own custom module.  I simply removed the "strict" command and moved on.

Jamie will doubtless be able to explain this better.

I have noticed that, the webmin API doesnt support the use of strict and

errors which are related to the API. Why isn't the API using strict?

Look at the javascript parameter. You should be able to pass in an arrayref

PEOPLES, MICHAEL P — 2013-03-20T21:49:20

I've been where you're at and gave up on some things.

Your best bet may be to go out and find a JavaScript framework (Dojo, JQuery, etc.) and try to incorporate that functionality into your code.  I'm not entirely sure how the Webmin web server will react to this however.  This won't be easy, but once you've figured out how to make it work within the Webmin environment, you can use other functionality it provides to enhance your modules.  There are lots of neat widgets and components to work with.

Then, you can share what you did with the rest of us and be a hero!

PEOPLES, MICHAEL P — 2013-03-20T19:23:41

What I always do is look through all of the other modules to see if I can find a function like the one I want, or at least one that is similar.

Then, examine the code in that module and modify it to your requirements.

If you're curious as to which modules might contain such functions, search for JavaScript references in the files.  You can do this finding all the files containing source code, creating a list of them, then looping through the list, searching each file for the "jsp" or other relevant tags.

This may not always work for you, but it's how I created my custom modules.

[webmin-devel] Select button

Emma wasanzy — 2013-03-20T19:14:47

Hello,

In the module am writing for tomcat, I want to provide two select
menu(dropdown menu). There a so many tomcat instance and each of them has
applications under them. Now, if someone want to upload a new jsp to a
particular tomcat say /var/lib/tomcat5/webapps/myapp is where the jsp will
be uploaded to. I want the first select menu to provide the list of all the
tomcat instances on the server(This I have done successfully).
The second select menu should contain all the applications under the
selected tomcat instance  from the first menu select. so if I select
tomcat5, the second select menu should load automatically all the
applications under tomcat5.

I know there is a javascript function that can do something like that
(onchange or so). But how can I do this? Any help will be appreciated much.

I have my two menu select with the code below:

 print &ui_table_row($text{'inst_select'},
                &ui_select("inst", $in{'inst'},
                    [ map { [ $_ ] } < at >insts ] ) );

This is not working
