我有一個角度問題， 我的變量的一部分在更改它們的值後沒有更新。 我的標題更新很好，我的頁腳只保留它們的初始值。AngularJS - 變量沒有在視圖中更新（不使用範圍）
下面是一些代碼：
<body>
<!-- Navigation -->
<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class="container" ng-controller="LanguageController as language">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<a class="navbar-brand" href="#"> {{ language.lblAppName }}</a>
</div>
<div class="vertical-center" id="language">
<label> {{ language.lblSelectLanguage }} </label>
<select ng-options="item for item in language.languages" ng-model="language.selectedLanguage" ng-change="language.changeLanguage()"></select>
<button ng-click="language.editLanguage()">{{ language.lblEditLanguage }}</button>
</div>
</div>
</nav>
<!-- there will be an ng-route directive here later on -->
<nav class="navbar navbar-inverse navbar-fixed-bottom" role="navigation">
<div class="container-fluid" ng-controller="LanguageController as language">
<div class="navbar-header">
<div class="navbar-brand"> {{ language.lblFooter }} </div>
</div>
<ul class="nav navbar-nav">
<li class="active"><a href="#"> {{ language.lblMainPage }} </a></li>
<li><a href="#">placeholder</a></li>
<li><a href="#">placeholder</a></li>
<li><a href="#">placeholder</a></li>
</ul>
</div>
</nav>
</body>
我所有的變量都更新在這裏很好，除了 「language.lblFooter」 和 「language.lblFooter」。
這裏是我的模塊
(function(){
// note: when calling angular.module("moduleName,["dependancies"]) a new module is created.
// when callung angular.module("moduleName") the module "modulename" is called.
/** @module
* Creation of the application module: CarViewer */
angular.module("carViewer", []);
}());
這裏是從代碼中提取的聲明更新變量：
var vm = this;
/**
* Initialise the retrieve sequence.
* @function
* @private
*/
function activate() {
// work fine the strings are returned from the backend correctly
return languageService.getLanguages()
.then(onLanguagesComplete, OnError);
}
/**
* Is called when the language retrieve is completed
* assign the different variables
* @function
* @private
* @param {string[]} data - The data returned by the getLanguages() function
*/
function onLanguagesComplete(data) {
vm.languages = data.languages; // list of all available languages
vm.strings = data.strings; // Two dimentional array containing the strings in every language
vm.selectedLanguage = vm.languages[DEFAULT_LANGUAGE];
assignStrings(DEFAULT_LANGUAGE);
};
/**
* Assign the new strings into the different variables
* @function
* @private
*/
function assignStrings(language) {
// Different labels
vm.lblSelectLanguage = vm.strings[language].lblSelectLanguage;
vm.lblEditLanguage = vm.strings[language].lblEditLanguage;
vm.lblAppName = vm.strings[language].lblAppName;
vm.lblMainPage = vm.strings[language].lblMainPage;
vm.lblFooter = vm.strings[language].lblFooter;
}
// and the changeLanguage that is called by the view
/**
* Allow the DOM to changes the language displayed,
* @function
* @public
*/
function changeLanguage(){
assignStrings(vm.languages.indexOf(vm.selectedLanguage));
}
所以每次變量正確更新除了在頁腳。 你們有什麼想法，爲什麼？
我看到這個問題可以通過使用$ scope.apply（）來解決，但我沒有使用$ scope？ 我試過這個。$ digest和這個。$ apply但是都不行。
編輯：我試圖只爲$範圍ingecting $範圍。目的，但它也不起作用。我想確切地說我使用$ http來檢索.json文件。
非常感謝。
爲什麼不使用$範圍？ –
@MikeTung，他的代碼似乎遵守約翰帕帕的「Angular Style Guide」。 –
@DavidR正好！ :) – Sherokan
