角JS“控制器作为”语法不起作用
角JS“控制器作为”语法不起作用
提问于 2015-03-31 14:14:12
我以前构建过一个AngularJS项目，并且熟悉语法。这一次，我的ng-controller="UniversalCtrl as universal"不工作，我已经尝试了一切。如果我使用universal.showHeader == true并将其更改为showHeader == true，它就能工作，但我需要它成为universal的变量。就像我说过的，我有其他的项目遵循同样的结构，而且它们工作得很好。
以下是我的HTML代码：
<!DOCTYPE html>
<html>
<head lang="en">
<meta http-equiv="cache-control" content="no-store" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta http-equiv="pragma" content="no-store" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=yes">
<link href="styles/MarkStrap.css" rel="stylesheet" />
<link href="styles/Site.css" rel="stylesheet" />
<script type="text/javascript" src="js/Angular/angular.min.js"></script>
<script type="text/javascript" src="js/Angular/angular-route.min.js"></script>
<script type="text/javascript" src="js/Universal/Universal.js"></script>
<script type="text/javascript" src="js/Universal/Filters.js"></script>
<script type="text/javascript" src="js/Universal/Directives.js"></script>
<title>WIN</title>
<link rel="shortcut icon" href="winIcon.ico">
</head>
<body ng-app="winApp" ng-controller="UniversalCtrl as universal">
<index-header ng-show="universal.showHeader == true"></index-header>
<ng-view></ng-view>
<script type="text/javascript" src="js/Applications/Applications.js"></script>
</body>
</html>下面是我的Universal.js设置：
(function () {
var winSystem = angular.module('winApp', ['ngRoute']);
winSystem.config(function ($sceProvider, $routeProvider) {
$routeProvider
.when('/Applications', {
templateUrl: "view-app.html",
controller: "AppController"
})
.otherwise({
templateUrl: "404.html"
})
});
winSystem.service("sharedData", function () {
var reloadData = false;
var beginAppLoad = false;
var reloadNotes = false;
self.httpGet = function (http, url, callback) {
http.get(baseUrl + url, {
headers: { "Session-Id": localStorage.ogSessionId }
}).success(function (data) {
callback(data);
}).error(function (data, status, headers, config) {
if (status == "401") {
localStorage.removeItem("ogSessionId");
localStorage.removeItem("ogUserId");
window.location.href = loginUrl;
}
});
};
self.httpPost = function (http, url, content, callback) {
http.post(baseUrl + url, {
Content: JSON.stringify(content)
}, {
headers: {
"Session-Id": localStorage.ogSessionId
}
})
.success(function (data) {
callback(data);
})
.error(function (data, status, headers, config) {
if (status == "401") {
localStorage.removeItem("ogSessionId");
localStorage.removeItem("ogUserId");
window.location.href = loginUrl;
}
});
};
});
winSystem.controller("UniversalCtrl", ['$scope', '$http', 'sharedData', function ($scope, $http, sharedData) {
var self = $scope;
self.sharedDataSvc = sharedData;
self.isLocal = false;
if (location.href.indexOf("localhost") > -1) {
self.isLocal = true;
} else self.isLocal = false;
self.account = {};
self.actions = [];
self.notifications = [];
self.alertCount = 0;
self.showAlert = false;
self.showHeader = true;
self.alertMessage = "";
}]);
})();回答 1

您正在将模型绑定到scope对象，而不是控制器实例。尝试：
winSystem.controller("UniversalCtrl", ['$http', 'sharedData', function ($http, sharedData) {
var self = this;
self.sharedDataSvc = sharedData;
self.isLocal = false;
if (location.href.indexOf("localhost") > -1) {
self.isLocal = true;
} else self.isLocal = false;
self.account = {};
self.actions = [];
self.notifications = [];
self.alertCount = 0;
self.showAlert = false;
self.showHeader = true;
self.alertMessage = "";
}]);我注意到您在服务sharedData上使用了自变量，但是还没有初始化它。同样的'var self = this;‘
