问题描述
我创建了一个简单的 Angular JS $routeProvider 解析测试应用程序.它给出了以下错误:
I have created a simple Angular JS $routeProvider resolve test application. It gives the following error:
Error: Unknown provider: dataProvider <- data
如果有人能指出我哪里出错了，我将不胜感激.
I would appreciate it if someone could identify where I have gone wrong.
index.html
<!DOCTYPE html>
<html ng-app="ResolveTest">
<head>
<title>Resolve Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js"> </script>
<script src="ResolveTest.js"></script>
</head>
<body ng-controller="ResolveCtrl">
<div ng-view></div>
</body>
</html>
ResolveTest.js
ResolveTest.js
var rt = angular.module("ResolveTest",[]);
rt.config(["$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>
推荐答案
问题是你在 index.html 的 body 标签上有 ng-controller="ResolveCtrl" 而在 $routeProvider 为 rt.html 指定相同的控制器.从 body 标签中取出控制器定义，让 $routeProvider 处理它.之后效果很好.
The problem is that you have ng-controller="ResolveCtrl" on your body tag in index.html when also in your $routeProvider you specify the same controller for rt.html. Take out the controller definition from your body tag and just let the $routeProvider take care of it. It works great after that.
