Question

我尝试运行一个类方法（在创建我的$uibModal的控制器中）一旦模态＆＃34;好的＆＃34;按钮已被按下。我的理解是modalInstance从组件返回一个模态对象，其中存在我的问题......我如何与父控制器而不是组件交互？

示例：

modalInstance.result.then(function () {
      // if close() called in component, do this in the parent controller
      this.users.splice(this.users.indexOf(user), 1);    
   }, function () {
      // if dissmised, do this
      console.log('modal-component dismissed at: ' + new Date());
});

这会引发错误：

TypeError：无法读取属性＆＃39;用户＆＃39;未定义的

这是一个带有关键项的Plunker： https://plnkr.co/edit/ZY3Kr9g3MuT1AxsQKfsj?p=catalogue

AngularJS 1.6，使用Angular Fullstack Generator 4.2.3

我已按照此文档：https://angular-ui.github.io/bootstrap/创建模态组件，模式效果很好。但无论我尝试什么，我都无法拼接我的用户群。请帮忙！

可能是因为回调中绑定错误from __future__ import print_function from AppKit import * # For development only. This takes a long time to complete as there are many symbols. import fcntl import os import signal shared_workspace = NSWorkspace.sharedWorkspace() def on_did_activate_application(notification): print('on_did_activate_application(notification = %s)' % notification) notification_center = shared_workspace.notificationCenter() did_activate_application_observer = notification_center.addObserverForName_object_queue_usingBlock_( NSWorkspaceDidActivateApplicationNotification, None, None, on_did_activate_application) def handle_signal(signum, frame): print('handle_signal(signum = %s, frame = <scrubbed>)' % signum) if signum == signal.SIGCONT: signal.signal(signal.SIGTSTP, handle_signal) elif signum == signal.SIGINT: notification_center.removeObserver_(did_activate_application_observer) CFRunLoopStop(CFRunLoopGetCurrent()) else: # https://stackoverflow.com/questions/13377773/proper-way-to-handle-signals-other-than-sigint-in-python signal.signal(signum, signal.SIG_DFL) os.kill(os.getpid(), signum) r, w = os.pipe() flags = fcntl.fcntl(r, fcntl.F_GETFL, 0) fcntl.fcntl(r, fcntl.F_SETFL, flags | os.O_NONBLOCK) def callout(f, call_back_types, info): # Note: The signal handler will run first. print('callout()') # Clear the pipe of NUL bytes. n = 0 while True: try: n += len(os.read(r, 100)) except OSError: break print('read %d byte(s)' % n) # Per https://developer.apple.com/documentation/corefoundation/cffiledescriptor?language=objc # "Each call back is one-shot, and must be re-enabled if you want to get another one." # Thus we need to re-enable call backs. CFFileDescriptorEnableCallBacks(f, kCFFileDescriptorReadCallBack) file_descriptor = CFFileDescriptorCreate(None, r, True, callout, None) CFFileDescriptorEnableCallBacks(file_descriptor, kCFFileDescriptorReadCallBack) run_loop_source = CFFileDescriptorCreateRunLoopSource(None, file_descriptor, 0) CFRunLoopAddSource(CFRunLoopGetCurrent(), run_loop_source, kCFRunLoopDefaultMode) signal.set_wakeup_fd(w) signal.signal(signal.SIGCONT, handle_signal) signal.signal(signal.SIGINT, handle_signal) signal.signal(signal.SIGTSTP, handle_signal) # For testing, configure a SIGALRM to be received every two seconds. signal.signal(signal.SIGALRM, lambda _1, _2: print('SIGALRM')) signal.setitimer(signal.ITIMER_REAL, 2, 2) print('about to call CFRunLoopRun()') CFRunLoopRun()，请尝试使用this将其显式绑定到父封闭范围：

使用modalInstance.result.then（）执行父控制器方法AngularJS
