我有一个项目的开发周期非常快，这会导致主app.js文件发生许多更改。该文件包含AngularJS应用程序的配置和控制器，该应用程序是项目的一部分。这产生了缓存问题，我尝试解决如下问题：
<script type="text/javascript">
var s = document.createElement('script')
s.setAttribute('src', 'assets/js/app-v2.js?v='+(new Date().getMilliseconds()));
document.body.appendChild(s);
</script>
然而，这给了我一个角度上的错误：
Failed to instantiate module appName due to:
Error: [$injector:nomod] Module 'appName' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
我的HTML设置为
<html ng-app="appName">....</html>
因此，我尝试在加载脚本后动态设置ng-app，但这也不起作用。给了我和前面一样的问题。我是否可以在加载app-v2.js文件期间或之后动态添加appName？
当我面临同样的问题时，我从stackoverflow中找到了这个答案。
bootstrap（）将为您调用AngularJS编译器，就像ng-app一样。
// Make module Foo and store $controllerProvider in a global
var controllerProvider = null;
angular.module('Foo', [], function($controllerProvider) {
controllerProvider = $controllerProvider;
});
// Bootstrap Foo
angular.bootstrap($('body'), ['Foo']);
// .. time passes ..
// Load javascript file with Ctrl controller
angular.module('Foo').controller('Ctrl', function($scope, $rootScope) {
$scope.msg = "It works! rootScope is " + $rootScope.$id +
", should be " + $('body').scope().$id;
});
// Load html file with content that uses Ctrl controller
$('<div id="ctrl" ng-controller="Ctrl" ng-bind="msg">').appendTo('body');
// Register Ctrl controller manually
// If you can reference the controller function directly, just run:
// $controllerProvider.register(controllerName, controllerFunction);
// Note: I haven't found a way to get $controllerProvider at this stage
// so I keep a reference from when I ran my module config
function registerController(moduleName, controllerName) {
// Here I cannot get the controller function directly so I
// need to loop through the module's _invokeQueue to get it
var queue = angular.module(moduleName)._invokeQueue;
for(var i=0;i<queue.length;i++) {
var call = queue[i];
if(call[0] == "$controllerProvider" &&
call[1] == "register" &&
call[2][0] == controllerName) {
controllerProvider.register(controllerName, call[2][1]);
}
}
}
registerController("Foo", "Ctrl");
// compile the new element
$('body').injector().invoke(function($compile, $rootScope) {
$compile($('#ctrl'))($rootScope);
$rootScope.$apply();
});
希望它能帮助你
