我想在呈现新视图(HTML)的ajax调用上动态加载角度控制器。
这就是我所拥有的:
视图示例。来自AJAX的HTML片段
<!-- CVS Pharmacy Extracare - Add View -->
<div ng-controller="cvsViewCtrl" class="container-fluid">
<div class="col-md-8 col-md-offset-2">
<h3 id="asset-title" class=""></h3>
<br>
<p>Member ID</p>
<input class="input-s1 block-elm transition" type="text" placeholder=""/>
<br>
<input class="add-asset-btn btn btn-success block-elm transition" type="button" value="Add Asset!" ng-click="prepareCVS();"/>
</div>
</div>
与视图相关的单独脚本
App.controller('cvsViewCtrl', ['$scope', '$http', function($scope, $http){
console.log('cvs view loaded');
$scope.prepareCVS = function() {
console.log('admit one');
}
}]);
以及加载它们的函数
$scope.setAddAssetView = function(a) {
console.log(a);
if($scope.currentAddView == a) {
console.log('view already set');
return;
}
$scope.currentAddView = a;
$('#main-panel').html('');
$http({
method: 'POST',
url: '/action/setaddassetview',
headers: {
'Content-Type': 'application/json',
},
data: {
asset: a,
}
}).then(function(resp){
// Success Callback
// console.log(resp);
var index = resp.data.view.indexOf('<s');
var script = resp.data.view.slice(index);
var html = resp.data.view.replace(script, '');
$('#main-panel').html( html );
$('#asset-title').text(a.name);
var indexTwo = a.view.indexOf('/add');
var scriptLink = insertString(a.view, indexTwo, '/scripts').replace('.html', '.js').replace('.', '');
console.log( scriptLink );
window.asset = a;
$.getScript(scriptLink, function(data, textStatus, jqxhr){
console.log('loaded...');
})
},
function(resp){
// Error Callback
console.log(resp);
});
}
当$ .getScript运行时,脚本会成功加载,但不会初始化控制器。我甚至尝试过:
var s = document.createElement('script');
s.type = 'text/javascript';
s.src = scriptLink;
s.innerHTML = null;
s.id = 'widget';
document.getElementById('switch-script').innerHTML = '';
document.getElementById('switch-script').appendChild( s );
这会使用正确的链接附加脚本,但仍然无法初始化。我该如何解决这个问题?

在您的应用中进行此更改,并确保在使用ng-controller渲染的html之前加载控制器文件。
var App = angular.module("app", [...]);
App.config(["$controllerProvider", function($controllerProvider) {
App.register = {
controller: $controllerProvider.register,
}
}]);
App.register.controller('cvsViewCtrl', ['$scope', '$http', function($scope, $http){
console.log('cvs view loaded');
$scope.prepareCVS = function() {
console.log('admit one');
}
}]);

这实际上不是处理事情的正确方法。
如果使用ui-router进行路由,则可以在resolve函数中加载控制器。一个很好的服务是ocLazyLoad。
可以这样做:
var app = angular.module('myApp', [
'ui.router',
'oc.lazyLoad',
]);
angular.module('myApp').config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/login');
$stateProvider
.state('main', {
url: '/main',
templateUrl: 'app/views/main.view.html',
controller: 'mainCtrl',
resolve: {
loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load('app/ctrls/main.ctrl.js');
}],
}
})
.state('second', {
url: '/second',
templateUrl: 'app/views/second.view.html',
controller: 'secondCtrl',
resolve: {
loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load('app/ctrls/controller_TWO.ctrl.js');
}],
}
})
});
当您从一个路线更改为另一个路线时,将在加载html之前触发解决,并且控制器将正确注册。
