Subject: [Xerte] Re: JS question in template_management.js

 

Ron,

This is probably better for the developer list.

Anyhow, on line 1007 (of the latest version) of template_management.js, you
see the expression that is used to get the tempate_id to be deleted.

delete_template(drag_manager.selected_items[x].id.substr(drag_manager.select
ed_items[x].id.indexOf("_"),drag_manager.selected_items[x].id.length));    

So: 

1. drag_manager.selected_items[x].id contains a string that determines
whther this item to be deleted is a folder or an LO. In this case it is
expected to be an LO and conatins something like 'file_43' for templateId 43
2. To get the 43 out of the string, the text from '_' to the end of the
string is taken:
 
drag_manager.selected_items[x].id.substr(drag_manager.selected_items[x].id.i
ndexOf("_"),drag_manager.selected_items[x].id.length
3. Then that string is passed to the delete_tempate function (in this case
43)

So perhaps, you should put your logic in the delete_template function...


Or even better, in the php function :
website_code/php/templates/delete_template.php because that's the function
that does all the work (it's called from delete_template by using AJAX).

Regards,

Tom

I'm in toolkits V1.7 (trying to move to 2 - this is part of the process) in
websitecode/scripts/template_management.js down around line 1030. This is
the section where courses are deleted. Since my customizations use a SQL
Server dbase to also store info on the courses, I want run a script to make
sure that the course(s) to be deleted are not assigned to students.

 

First I need to get the 'templateID' of the course, but not sure how to do
that, I'm not good with js. Does anyone know if I can pull the 'templateID'
of the course(s) that have been clicked in the workspace delete window at
this point? I'm wondering if the document object contains the templateID(s)
at this point and if so what syntax I'd use to get them.

 

Next, any suggestion on what is socially acceptable to js in terms of
running a query on my SQL Server database to see if students are currently
assigned?

 

Thanks for any suggestions
