Hello!

What am I trying to do?

I am looking for a system to help less confident and non wiki users manager people in Groups. The immediate need was to enable people to be added to a current group which I think the code below achieves albiet in a clumsy way.

The more difficult thing would be to present the user with a current list of people and then when they un-tick the box, those people would be removed from the group.

The way I can see of doing it is as follows:

• Read the current list of people into an array in JavaScript
• Provide the formatted table so it displays as per below via JavaScript - for-next loop
• As the user unticks the box, then the user would not be in the revised group - on.change to change the final strong in real time
• When Submit is pressed, the new group is written - change the Group Variable definition in the Group topic.

I have hit two issues:

• knowledge of JavaScript to:
  • do the for loop
  • provide the updated string as the user clicks the buttons
• changing the topic text - I can add text as the example proves but change the current contents......hmmm.....
  • My solution would be to either:
    • Use a template and then in effect create a new revision of the topic using a template but this would ignore/lose any modifications by the user.
    • Use some sort of RegEx expression to capture the text of the current topic from the start to * Set GROUP and the text afterwards to the end.....this would form a new topic and enable any comments/additional info to be preserved......however, I cannot write RegEx expressions!

Any help gratefully received as ever!

How did I fix it?

In this example, Set CURRGROUPLIST =  Comma, Seperated, List, AbcAbc in the becomes:

<ul>
<li> Set CURRGROUPLIST =  Comma, Seperated, List, <span class="foswikiNewLink">AbcAbc<a href="/bin/edit/Sandbox/AbcAbc?topicparent=Sandbox.CommentFormTopic" rel="nofollow" title="Create this topic">?</a></span> 
</li>
</ul>

which causes the location parameter in the CommentPlugin to fail as it does not match the text in the topic.

The key to success was enclosing the %COMMENT% in the <noautolink> tag which stopped FosWiki converting it to a hyperlink with the create topic option at the end.

The Code in action

This extracts the Variable from the topic ready for processing:

• Set CURRGROUPLIST = Comma, Seperated, List, AbcAbc, NeilGood, SimonLatham

<noautolink>
%COMMENT{type="ListAddItem" target="CommentPluginTest" location="%CURRGROUPLIST%"}%
</noautolink>

Item to Add:

An alternative form with the same aim:

NewGroupTopicDefaultCarryOverText - stuff for a new group

-- Main.NeilGood - 31 Mar 2009

NewGroupTopicDefaultCarryOverText - stuff for a new Group topic incase a previous topic is not supplied

-- Main.NeilGood - 31 Mar 2009

NewGroupTopicDefaultCarryOverText

-- Main.NeilGood - 31 Mar 2009

Sample format for Including/Excluding items on the list

Here is the user Interface but this is where I think JavaScript is needed to change the string as the User checks/unchecks the items.

Item	Include?
Comma
Seperated
List
AbcAbc
NeilGood
SimonLatham
