重新初始化 Angular.js 控制器 [英] Reinitialize an Angular.js controller

问题描述

如果您有一个控制器来操作 Angular.js 中的 $scope 变量，是否有一种惯用的方法:

if you have a controller to manipulate $scope variables in Angular.js, is there an idiomatic way to:

• 重置控制器的 $scope 和
• 重启控制器初始化?

对于复杂的控制器，不必将每个变量重置为其初始值会非常方便，特别是如果您真正想要的是控制器和范围的简单重新初始化.但是，通过 $location.path() 再次导航到相同的 URL 没有帮助.

For complex controllers it would be very convenient not to have to reset every variable to it's initial value, especially if what you really want is a simple reinitialization of the controller and the scope. Navigating to the same URL again via $location.path() doesn't help, though.

假设我不能使用任何 $window.location hack，因为这会违反 Chrome Packaged Apps 中的 CSP.

Suppose I can't use any $window.location hack because this would violate the CSP in Chrome Packaged Apps.

推荐答案

刚问完，我终于找到了一种使用 $route.reload().

Just after asking, I finally found one way to solve this using $route.reload().

myapp.Controller('SampleController', function($location, $route) {

  $scope.navTo = function(url) {
    if ($location.path() === url) {
      $route.reload();
    } else {
      $location.path(url);
    }
  }

});

我仍然在想，一定有一些更优雅的解决方案，但这绝对适合我.

I'm still thinking, that there must be some more elegant solution, but this definitely works for me.
