问题描述
我创建了一个简单的角度JS $ routeProvider决心测试应用程序。它提供了以下错误:
错误:未知提供商:dataProvider中< - 数据
我想AP preciate,如果有人可以找出我已经错了。
index.html的
<!DOCTYPE HTML>
< HTML NG-应用=ResolveTest>
< HEAD>
<标题>解决测试与LT; /标题>
&所述; SCRIPT SRC =https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js> < / SCRIPT>
&所述; SCRIPT SRC =ResolveTest.js>&下; /脚本>
< /头>
<机身NG控制器=ResolveCtrl>
< DIV NG-视图>< / DIV>

ResolveTest.js
VAR RT = angular.module(ResolveTest,[]);rt.config([$ routeProvider功能($ routeProvider)
{
$ routeProvider.when(/,{
templateUrl:rt.html
控制器:ResolveCtrl
解析:{
数据:[$ Q,$超时功能($ Q $超时)
{
变种推迟= $ q.defer(); $超时(函数()
{
deferred.resolve(我的数据);
},2000); 返回deferred.promise;
}]
}
});
}]);rt.controller(ResolveCtrl,[$范围,数据功能($范围,数据)
{
的console.log(数据+数据);
$ scope.data =数据;
}]);
rt.html
<跨度> {{}数据}< / SPAN>
的问题是,你有 NG-控制器=ResolveCtrl
在索引你的身体标记。当还在你的$ routeProvider您指定rt.html相同的控制器HTML。从你的身体标记取出控制器的定义,只是让$ routeProvider照顾它。这之后的伟大工程。
I have created a simple Angular JS $routeProvider resolve test application. It gives the following error:
Error: Unknown provider: dataProvider <- data
I would appreciate it if someone could identify where I have gone wrong.
index.html
<!DOCTYPE html>
<html ng-app="ResolveTest">
<head>
<title>Resolve Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js"> </script>
<script src="ResolveTest.js"></script>
</head>
<body ng-controller="ResolveCtrl">
<div ng-view></div>
</body>
</html>
ResolveTest.js
var rt = angular.module("ResolveTest",[]);
rt.config(["$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>
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.
