Javascript 动态添加AngularJS脚本

javascript angularjs

Javascript 动态添加AngularJS脚本,javascript,angularjs,Javascript,Angularjs,我有一个项目，它有一个非常快速的开发周期，这会导致主app.js文件发生很多变化。此文件包含用作项目一部分的AngularJS应用程序的配置和控制器。这就产生了缓存问题，我尝试如下解决： <script type="text/javascript"> var s = document.createElement('script') s.setAttribute('src', 'assets/js/app-v2.js?v='+(new Date().getMillise

我有一个项目，它有一个非常快速的开发周期，这会导致主app.js文件发生很多变化。此文件包含用作项目一部分的AngularJS应用程序的配置和控制器。这就产生了缓存问题，我尝试如下解决：

<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>

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应用程序，但这也不起作用。给了我和之前一样的问题。我是否可以在加载app-v2.js文件期间或之后动态添加appName？

我在stackoverflow中找到了这个答案，当时我正面临同样的问题

bootstrap将为您调用AngularJS编译器，就像ng应用程序一样

// 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();
});

希望它能帮助您

缓存问题的本质是什么？文件已更新，但刷新时仍会获得旧版本？如果是这样，我不明白如何动态设置ng应用程序helps@NewDev，出于某种原因，即使该文件在服务器上更新，我在调用它时也会收到一个304 Not Modified标志。好的，但您打算如何使用dynamic ng app解决此问题？@NewDev，我假设我收到的错误是由于在调用js文件之前设置了ng app。如果不是这样的话，我该如何解决我得到的错误，并保持这个添加js文件的版本控制方法呢
