Kevin Brown 55f995ea21 Fixed data-ajax-url fallback ... This fixes the fallback path for the `data-ajax-url` attribute on elements. As this attribute was previously supported in Select2, the attribute has been migrated to the new, nested format of the url and triggers a deprecation warning when it is used. Because of a fix to the `data-*` attribute parsing made in a9f6d64 that allowed for nested attributes to be parsed correctly in modern browsers under jQuery 1.x, the deprecation warning would be triggered but the attribute would no longer actually be used. This also fixes some of the `.data` calls to use the camel cased version of the key instead of the dashed version, which is the preferred key and will be enforced in future versions of jQuery as the only way to access data attributes. Now in situations where the `dataset` attribute is used by Select2, it combines the results of both `$e.data()` and `e.dataset` when generating the object containing all of the options. This will the `dataset` fix to still be used, while also still relying on jQuery to do additional parsing on any options that it can. The `dataset` fix is now only used on jQuery 1.x, as that is the only version of jQuery affected by the dash issue. This is done using version number parsing on the `$.fn.jquery` property that is defined by jQuery. As this property is not defined in Zepto and many other jQuery compatible checks, we only include the fallback if the property is available. This assumes that any jQuery compatible libraries that are in use will not include the same dash issue, which we believe is a safe assumption given that it did not match the HTML `dataset` specification. This also adds a few tests to ensure that the deprecated attributes still continue to function. This closes https://github.com/select2/select2/issues/3086.		2015-02-27 20:11:13 -05:00
