我要当一个输入字段模糊一些数据提交给服务器。用户也应该能够通过pressing模糊输入字段中输入。

I want to submit some data to the server when a input field is blurred. The User should also be able to blur the input field by pressing enter.

不幸的是这将导致以下： $ rootScope：inprog：$正在进行中的错误已经适用

Unfortunately this results in the following: $rootScope:inprog: $apply already in progress error.

Plunkr - ！在此先感谢

Plunkr - thanks in advance!

推荐答案

下面是发生了什么：

该模糊同步执行，并立即触发处理程序没有完成的第一个摘要。

The blur is executed synchronously and immediately triggers the handler without finishing the first digest.

在我看来，这是不是与你的code的一个问题，而是一个角度错误。我一直在试图想出一个更好的解决方案，但我只能找到：

In my opinion, this is not a problem with your code, but rather an Angular bug. I've been trying to think of a better solution, but I can only find:

app.controller('BlurCtrl', function($scope, $timeout) {
  $scope.blurModel = "I'm the value"

    $scope.blurOnEnter = function( $event ) {
      if ( $event.keyCode != 13 )
        return

      // this will finish the current digest before triggering the blur
      $timeout(function () { $event.target.blur() }, 0, false);
    }

    $scope.onBlur = function() {
    $scope.result = this.blurModel
    }
})
