angular-directive - jQuery单击事件不更新范围

Question

在指令中，单击jQuery元素时，我正在更新范围。但它不起作用。什么是正确的方法来做到这一点？

angular.module('app.directives', []).directive('newContent', function() { 

    return { 

    link: function(scope, element, attrs) { 

     var title = element.find('h1'); //getting the element 
     scope.show = true; 

     var that = scope; 

     title.on('click', function(){ 

     scope.show = false; //not working 

     }) 

    } 

    } 

})

尝试这种使用scope.$apply或更好performancce使用scope.$evalAsync

scope.$apply(function(){ 
     scope.show = false; 
    }) 

var appModules = ['app.directives'] 
 

 
var app = angular.module('plunker', appModules); 
 

 

 
app.controller('MainCtrl', function($scope) { 
 
    $scope.name = 'World'; 
 
}); 
 

 

 

 
angular.module('app.directives', []).directive('newContent', function() { 
 

 
    return { 
 

 
    link: function(scope, element, attrs) { 
 
     
 
     var title = element.find('h1'); 
 
     scope.show = true; 
 
     
 
     var that = scope; 
 

 
     title.on('click', function(){ 
 
     
 
    scope.$evalAsync(function() { 
 
     scope.show = false; 
 
    ); 
 
    }) 
 

 
    } 
 

 
    } 
 

 
})
