您可以使用ng-blur指令。

<input type="text" ng-blur="ValidateBlur()" />

模块/控制器设置代码：

var app = angular.module("testApp", []);

app.controller("DarrenController", function($scope) {
    $scope.Text = "Testing...";

    $scope.ValidateBlur = function() {
      alert('Validating');
    }
});

<强> HTML：

  <body ng-app="testApp">
    <div ng-controller="DarrenController">
       <input type="text" ng-blur="ValidateBlur()" />
    </div>
  </body>

Answer 2

// HTML

<input type="text" ng-model="search" placeholder="Search ... " ng-focus="focusMsg()" ng-blur="blurMsg()">

//控制器

  $scope.focusMsg = function () {
            console.log('Focus');
        }

  $scope.blurMsg = function () {
            console.log('Blur');
        }
