我正在尝试编辑ng-controller
元素之外的视图。我能够通过使用$rootScope
和dom操作来解决它,但我想知道如何通过原生angularjs解决它?
HTML:
<body>
<div class="container">
<div class="block" ng-controller="BlockController as block">
<div><strong>Name:</strong> {{ block.name }}</div>
<a href ng-click="block.edit()">Edit</a>
</div>
</div>
<div class="container-editor">
<div id="block-editor"></div>
</div>
</body>
JS:
angular.module('app', [])
.controller('BlockController', BlockController);
function BlockController($compile, $scope)
{
this.name = 'default name';
this.edit = function() {
var $editor_html = ' <input type="text" ng-model="block.name" name="name" /> <a href ng-click="block.save()">Save</a>';
$editor_html = $compile($editor_html)($scope);
angular.element(document.querySelector("#block-editor")).html('').append($editor_html);
};
this.save = function() {
// save block
angular.element(document.querySelector("#block-editor")).html('');
};
}
这是示例

.directive('parent', function() {
return {
controller: function() {
this.catchChild = function(child) {
// code...
};
}
};
})
.directive('child', function() {
return {
require: '^parent',
link: function($scope, $element, $attrs, parentController) {
$scope.jump = function() {
// I'm jumping...
parentController.catch($scope);
};
}
};
})

(*)您可以将多个指令作为数组传递
angular.module('app', [])
.directive('parent1', function() {
return {
controller: function() {
this.fn1 = function(child) {
// code...
};
}
};
})
.directive('parent2', function() {
return {
controller: function() {
this.fn2 = function(child) {
// code...
};
}
};
})
.directive('child', function() {
return {
require: ['^parent1', '^parent2'],
link: function($scope, $element, $attrs, controllers) {
var parent1Controller = controllers[0];
var parent2Controller = controllers[1];
parent1Controller.fn1();
parent2Controller.fn2();
}
};
})
