我创建了一个简单的Angular JS $ routeProvider解决测试应用程序。它给出以下错误:
Error: Unknown provider: dataProvider <- data
如果有人可以确定我哪里出了问题，我将不胜感激。
index.html
<!DOCTYPE html>
<html ng-app="ResolveTest">
<head>
<title>Resolve Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js"> </script>
<script src="ResolveTest.js"></script>
</head>
<body ng-controller="ResolveCtrl">
<div ng-view></div>
</body>
</html>
ResolveTest.js
var rt = angular.module("ResolveTest",[]);
rt.config(["$routeProvider",function($routeProvider)
{
$routeProvider.when("/",{
templateUrl: "rt.html",
controller: "ResolveCtrl",
resolve: {
data: ["$q","$timeout",function($q,$timeout)
{
var deferred = $q.defer();
$timeout(function()
{
deferred.resolve("my data value");
},2000);
return deferred.promise;
}]
}
});
}]);
rt.controller("ResolveCtrl",["$scope","data",function($scope,data)
{
console.log("data : " + data);
$scope.data = data;
}]);
rt.html
<span>{{data}}</span>
最佳答案
问题是，当您也在$ routeProvider中为rt.html指定相同的 Controller 时，在index.html的body标记上具有ng-controller="ResolveCtrl"。从body标记中删除 Controller 定义，然后让$ routeProvider处理它。之后效果很好。
