#6158 Fixed replaceWith from throwing errors on non existant elements.
#6158 修正 replaceWith 没有找到元素时,抛出一个异常.
#7340 We now use a single capturing handler to simulate bubbling focusin/focusout event on non-IE browsers. Allows native DOM methods to fire events other than the currently active one back into jQuery.
#7340 我们现在使用一个单例模式的捕捉器来模拟focusin / focusout冒泡事件,在非IE浏览器。允许原生DOM方法触发事件,除了当前已进入jQuery的回退事件.
#8353 Reverted. Adds a catch block in resolveWith so that the finally block gets executed in IE7 and IE6. #8353 Fixes #8438 – an issue where the full functions stack wasn’t visible when debugging in Google Chrome.
Reverted.在resolveWith中添加一个catch块,以便在IE7和IE6下能够捕捉到finally。修正#8438这个问题--在Chrome调试时，full functions stack不可见。
#8380 Make it so that $(‘:text’) matches <input> as ‘type=text’ is the implied default.
#8380 类似(‘:text’)的语法能够匹配<input>，例如”type=text“就是一个默认的实现。
#8421 Makes sure resolveWith can be called with only one parameter.
#8421 确保resolveWith只有一个参数。
#8423 Never set X-Requested-With header automagically for cross-domain requests. Fixes an issue where all cross-domain ajax requests are pre-flighted and require extra additional options.
当跨域请求时，从不自动设置头部X-Requested-With。修正一个问题where all cross-domain ajax requests are pre-flighted and require extra additional options.
#8456 Fixed an issue where trigger(‘mouseover’) was no longer triggering mouseenter. We make sure parent is not null before crawling into its lap, so mouseenter is triggered on a mouseover event.
#8509 Makes URL regexp less overzealous and ensures it recognizes URL schemes which do not contain a conformant hierarchical structure (as per section 2.1.2 of#http://www.ietf.org/rfc/rfc2718.txt). Also adds about: and adobe air’s app: and app-storage: to the list of local protocols and provides a failover in case document.location is illformed.
#8536 Introduced submodules to the jQuery repository on GitHub.
在jQuery GitHub的知识库中引进子模块
#8381 Fixed .is(“div”) to work on disconnected nodes in IE 9.
修正 .is("div")可以工作在IE9分离的节点上.
#8316 Fixed .offset() setter on fixed elements in WebKit.
#8316 修正 .offset() 可以设置在fixed定位的元素上。
#3333 Fixed incorrect .css(“marginRight”) in WebKit.
#3333 修正 .css(“marginRight”)的错误
