| jbe/bsw@0 | 22 This function inserts a link into the active slot. It may be either an internal application link ('module' given and 'view' or 'action' given), or a link to an external web page ('external' given), or a link to a file in the static file directory of the application ('static' given). |
| jbe/bsw@0 | 23 |
| jbe@12 | 24 When passing a table as "partial" argument, AND if partial loading has been enabled by calling ui.enable_partial_loading(), then ui._partial_load_js is |
| jbe@12 | 25 used to create an onclick event (onsubmit event for action links). The |
| jbe@12 | 26 "partial" setting table is passed to ui._partial_load_js as first argument. |
| jbe@12 | 27 See ui._partial_load_js(...) for further documentation. |
