Lowercase avalon is used because AMD module names are +// derived from file names, and Avalon is normally delivered in a lowercase +// file name. Do this after creating the global so that if an AMD module wants +// to call noConflict to hide this version of avalon, it will work. + +// Note that for maximum portability, libraries that are not avalon should +// declare themselves as anonymous modules, and avoid setting a global if an +// AMD loader is present. avalon is a special case. For more information, see +// https://github.com/jrburke/requirejs/wiki/Updating-existing-libraries#wiki-anon + if (typeof define === "function" && define.amd) { + define("avalon", [], function() { + return avalon + }) + } +// Map over avalon in case of overwrite + var _avalon = window.avalon + avalon.noConflict = function(deep) { + if (deep && window.avalon === avalon) { + window.avalon = _avalon + } + return avalon + } +// Expose avalon identifiers, even in AMD +// and CommonJS for browser emulators + if (noGlobal === void 0) { + window.avalon = avalon + } + return avalon + +})); \ No newline at end of file diff --git a/template/src/admin/admin.html b/template/src/admin/admin.html index bde4fb9b..37493d79 100644 --- a/template/src/admin/admin.html +++ b/template/src/admin/admin.html @@ -69,8 +69,8 @@ diff --git a/template/src/admin/user/user_list.html b/template/src/admin/user/user_list.html index 8e8c0f4b..8227997f 100644 --- a/template/src/admin/user/user_list.html +++ b/template/src/admin/user/user_list.html @@ -64,7 +64,7 @@
