[Xerte] Re: JS question in template_management.js

[Tom Reijnders]

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.selected_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.indexOf("_"),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
