Fix undefined variables There were a few undefined variables being referenced within the Select2 code. The JSHint configuration has been modified to fail if there are undefined variables being referenced, including any global variables. There is an exception that is being made for the jQuery shim, as it must try to find the global jQuery references. An exception is made for the test helpers, as the SauceLabs reporting variables are not camelCase, and would normally trigger warnings.

Work on the AMD scaffolding This will make it far easier to ensure that components are in their own modules as well as make it possible to have custom builds of Select2. 2014-08-27 02:01:42 +04:00			`define(function () {`
Changed how the builds are done This adds a check that triggers an error if Select2 was not able to detect a copy of jQuery on the page. This should help users when they are setting up Select2. Breaking change: The full build no longer includes jQuery. Previously, the full build included all requirements for Select2, including jQuery, which meant that anyone looking for the optional requirements had to possibly include multiple versions of jQuery on their page. This means that anyone requiring Select2 to also bundle jQuery will now need to include jQuery on their pages alongside Select2. A copy of jQuery is included in the repository. Breaking change: The AMD build of Select2 will now correctly wrap the code in a `define` block. It will still create the named blocks inside of the code, which should be valid in most AMD build systems, so now Select2 is compatible with cases where the file does not have the same name as the Select2 module name. Breaking change: Select2 will re-use the AMD methods if they are available on the page, but it will not longer leak the included AMD loader to the global scope. The AMD methods will still be available on the `jQuery.fn.select2.amd` namespace. The `mock.js` test file has been renamed to `helpers.js` and will handle the escalation of the `require` and `define` variables to the global scope. It should be included in all test files, or the tests will fail. This closes https://github.com/select2/select2/issues/2946. 2015-01-22 22:49:39 +03:00			`var _$ = jQuery \|\| $;`

Linted select2/utils For the most part this was semicolon fixes, but there was a function, `calledMethod`, which did need to be moved out of the loop. 2014-09-21 23:44:30 +04:00			`});`
