Lauke" Date: Fri, 14 Apr 2017 09:19:00 +0100 Subject: Replace dropdown backdrop hack with cleaner JS-only hack * Replace backdrop with simple noop mouse listener As discussed in https://github.com/twbs/bootstrap/pull/22422 the current approach of injecting a backdrop (to work around iOS' broken event delegation for the `click` event) has annoying consequences on touch-enabled laptop/desktop devices. Instead of a backdrop `

`, here we simply add extra empty/noop mouse listeners to the immediate children of `` (and remove them when the dropdown is closed) in order to force iOS to properly bubble a `click` resulting from a tap (essentially, method 2 from https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html) This is sufficient (except in rare cases where the user does manage to tap on the body itself, rather than any child elements of body - which is not very likely in an iOS phone/tablet scenario for most layouts) to get iOS to get a grip and do the correct event bubbling/delegation, meaning the regular "click" event will bubble back to the `` when tapping outside of the dropdown, and the dropdown will close properly (just like it already does, even without this fix, in non-iOS touchscreen devices/browsers, like Chrome/Android and Windows on a touch laptop). This approach, though a bit hacky, has no impact on the DOM structure, and has no unforeseen side effects on touch-enabled laptops/desktops. And crucially, it works just fine in iOS. * Remove dropdown backdrop styles * Update doc for dropdowns and touch-enabled devices --- js/src/dropdown.js | 23 +++++++++-------------- 1 file changed, 9

Subject: Add iOS hack to tooltips

Same hack as in https://github.com/twbs/bootstrap/pull/22426 (modulo the selector, which is wrong in that PR and will be updated in a separate PR) to get tooltips to work correctly on iOS. Dynamically adds/removes empty (`noop`) `touchstart` event handlers to all children of `<body>` in order to coax iOS into proper event delegation/bubbling

Subject: Update nav and navbar HTML markup

According to the docs, you just need to apply the `navbar-nav` to an
`<ul>` tag in a list-based navbar. In fact, `navbar-nav` seems to
override all the css properties set by `nav`.

Also, `nav-item` class should be used only for `<li>` tags, or in
conjunction with `<a>` tags to entirely avoid the list-based approach.

This commit removes the redundant `nav` class from `navbar-nav` `<ul>`
tags, moves `nav-item` from `<a>` tags to `<li>` tags and properly
adds `nav-item` class to `<li>` tags where missing.
