From 865c23330a9e891024e2df3696dfe5a827ed545c Mon Sep 17 00:00:00 2001 From: Thomas Berezansky Date: Wed, 24 Aug 2011 11:31:59 -0400 Subject: [PATCH] Remove in-template javascript, add script files Adds support for a print_custom.js file and an org unit specified file. If either exists and contains a print_custom function it will be called before printing to allow for DOM manipulation. If neither exists the print_win.js file will call all functions it has defined. In addition, if any code sets do_print to false the window will close instead of attempting to print. The print_custom function will receive the type of template used, if any. This only applies to "Receipt Template" based print jobs, and the type in question is the "Type" that shows in the template editor. Functions defined in print_win.js: print_init Main function, checks for print_custom and does final printing print_do_sums Does summing of values. print_check_alt Does swapping out of template blocks with display:none styling. print_check_noprint Disables printing under certain circumstances. For more information about usage of the print_do_sums, print_check_alt, and print_check_noprint functions check the comments in print_win.js.
