When xhr.send throws an exception synchronously, the onerror handler may have
been called already which, unchecked, makes the exception bubble up outside of
jQuery.ajax.
We now catch the exception pre-emptively and only rethrow if we know it hasn't
already been notified through the onerror handler.
Fixes#14683
IE11 fixed the checkbox defaultValue issue but not textarea. Rather than
creating a new detect name I'm reusing the old one to protect anyone who
is unwisely using this externally. Re-fixing the defaultValue when it
doesn't need to be done is not a problem, so leave that code for IE11.
Fixes#14716
Closes gh-1495
This hook was relevant for BlackBerry 4.7 which is no longer supported.
But this code path now raises error in IE10-11 (#14686) in 1.x-master branch.
So to just to be safe, also add test for IE issue to this branch too.
For CommonJS environments where the global already has a document, it is expected
that if a global is needed, the user can attach the global.
Fixes#14645.
Tracked bower dependencies are located at "src/sizzle" and "test/libs".
The source-destination mapping is in the Gruntfile.
When updating a bower dependency, update the version in bower.json, run
`grunt bower`, and then commit the result. When adding a dependency,
update the bowercopy task accordingly.
Fixes#14615.
Closes gh-1452.
In the most outer IIFE it’s not yet known if the global is window or not.
Using the window variable to denote the global was misleading in that case,
especially that the code didn’t make such assumption, requiring to provide
a Web-like window separately. Renaming window to global clears the confusion.
This also reduces memory leaks if the element is removed without cleaning
events (e.g with native DOM operations).
Not pickable into the 1.x branch because oldIE still needs this.
In 1.x if the support test executes before doc ready, it may not be able
to return a result yet. In such a case, we protect ourselves from future
breakages, allowing only for the ones before doc ready.
Since in 2.x lazy support tests attach test elements to docElem, not body,
such a guard is unnecessary.
