deferred.resolve( args )返回: Deferred
描述: 解决Deferred（延迟）对象，并根据给定的args参数调用任何完成回调函数（doneCallbacks）。

添加的版本: 1.5deferred.resolve( args )
args
类型: Object
传递给完成回调函数（doneCallbacks）的可选的参数。
当延迟对象被 resolved 时，任何通过 deferred.then或deferred.done 添加的 doneCallbacks，都会被调用。回调函数的执行顺序和它们被添加的顺序是一样的。传递给 deferred.resolve() 的 args 参数，会传给每个回调函数。当延迟对象进入 resolved 状态后，再添加的任何 doneCallbacks，当它们被添加时，就会被立刻执行，并带上传入给 .resolve()的参数。有关详细信息，请参阅文件Deferred object 。
