我是AngularJS的新手。我正在使用下面的代码来实现延迟加载依赖。AngularJS 1.2.0：延迟加载控制器和模板
https://github.com/matys84pl/angularjs-requirejs-lazy-controllers/
这与1.0.7伟大的工作，但延迟承诺无法加载temaplate在1.2.0版本。
在js/lib/utils/route-config.js
routeDefinition.template = function() {
/*
* Here is the problem, 'html' is undefined on page load.
* But if we click the menu navigation, the 'html' is getting loaded.
* I am not sure how to achieve promise for loading template in RequireJS.
*/
return html;
};
routeDefinition.controller = controllerName;
routeDefinition.resolve = {
delay:function ($q, $rootScope) {
defer = $q.defer();
if (!html) {
var dependencies = [controllerName, "text!" + templateUrl];
if (directives) {
dependencies = dependencies.concat(directives);
}
require(dependencies, function() {
var controller = arguments[0],
template = arguments[1];
for (var i = 2; i < arguments.length; i++) {
lazyDirectives.register(arguments[i]);
}
$controllerProvider.register(controllerName, controller);
html = template;
defer.resolve();
$rootScope.$apply()
})
} else {
defer.resolve();
}
return defer.promise;
}
我已经改变了代码与下面的一个，即而不是使用template，我已经把它改成templateUrl和它的作品完美。由于我在salesforce.com中实现了它，并且Visualforce页面不支持html扩展，所以我不想使用templateUrl。
routeDefinition.templateUrl = 'js/'+templateUrl;
routeDefinition.controller = controllerName;
routeDefinition.resolve = {
delay:function ($q, $rootScope, $http) {
defer = $q.defer();
if (!html) {
//var dependencies = ["lib/text!" + templateUrl, controllerName];
var dependencies = [controllerName];
if (routeDependends) {
dependencies = dependencies.concat(routeDependends.directives);
dependencies = dependencies.concat(routeDependends.services);
dependencies = dependencies.concat(routeDependends.filters);
}
require(dependencies, function() {
var controller = arguments[0],
//template = arguments[0],
incCnt = 1,
directiveCnt = (routeDependends.directives.length+incCnt),
serviceCnt = (routeDependends.directives.length+routeDependends.services.length+incCnt),
filterCnt = (routeDependends.directives.length+routeDependends.services.length+routeDependends.filters.length+incCnt);
$controllerProvider.register(controllerName, controller);
if(routeDependends.directives.length > 0)
for (var i = incCnt; i < directiveCnt; i++) { onDemandDependencies.registerDirectives(arguments[i]); }
if(routeDependends.services.length > 0)
for (var i = directiveCnt; i < serviceCnt; i++) { onDemandDependencies.registerServices(arguments[i]); }
if(routeDependends.filters.length > 0)
for (var i = serviceCnt; i < filterCnt; i++) { onDemandDependencies.registerFilters(arguments[i]); }
//html = template;
defer.resolve();
$rootScope.$apply()
});
} else {
defer.resolve();
}
return defer.promise;
}
}
console.log(routeDefinition);
return routeDefinition;
任何帮助表示赞赏。提前致谢。
在您的浏览器的开发控制台中是否有错误？ – jpmorin
@jpmorin不干净，干净。但是，当我控制'html'时，它说在页面加载时未定义，而在浏览页面时，它返回正确的html。 – moustacheman
我来到这里后，您对github的评论。我遇到了同样的问题，我用[这种方法]解决了（http://ify.io/lazy-loading-in-angularjs/）。希望这可以帮助。 – Cosmitar
