问题描述
我想知道，这样的$ HTTP请求的URL不同的基于点击在NG-重复列表中的元素如何动态地更改$ HTTP调用。但我卡住了。
I want to know how to dynamically change an $http call so that the $http request URL differs based on the element that is clicked in an ng-repeat list. But I'm stuck.
目前，我有一个NG重复设置我的索引页：
Currently, I have an ng-repeat set up on my index page:
<div ng-repeat="team in nt.getStandings">
<a href="#/nation-details/{{team.team_id}}"><h2>{{team.team_name}}</h2></a>
<p>Team ID = {{team.team_id}}</p>
</div>
变量 getStandings 是从API通过$ HTTP调用拍摄。像这样：
The variable getStandings is taken from an API via an $http call. Like so:
return $http.get(
'http://api.com/standings/1005?Authorization=xxxx'
)
.success(function(data) {
return data;
})
.error(function(err) {
return err;
});
然后StandingsService连接到 getStandings 变量在我的控制器。
1005，是它要求一个特定的阵列，在这种情况下，一个特定的体育比赛中，从比赛的阵列的属性
"1005" is a property which calls a specific array, in this case a particular sporting competition, from an array of competitions.
所以，我使用的是NG-重复列出竞争中的所有团队我的索引页上。
So, on my index page I'm using ng-repeat to list all teams within that competition.
正如你可以在HTML上面，我已经联系各队看到，这样它会动态生成该追加的URL TEAM_ID 来结束，这使用 $ routeParams 我定义为变量 whichTeam 。
As you can see on the html above, I have linked each team so that it dynamically generates a URL which appends the team_id to the end, which using $routeParams I define as the variable whichTeam.
<h1>Dynamic Team ID = {{whichTeam}}</h1>
这工作得很好，是按照点击，球队动态生成的球队ID。
This works fine, the team ID is generated dynamically according the team that is clicked.
就像上面的'StandingsService'，我有一个名为TeamService其它服务，这使得一个$ http请求拉队的数据。目前，虽然它被设置静态地拨打电话，以一个人的团队 - 我想在该whichTeam变量服务要花那么呼叫变化，这取决于被点击的团队
Just like 'StandingsService' above, I have another service called 'TeamService' which makes an $http request to pull team data. Currently though it is set up statically to make a call to one individual team - I want to make the service take in the whichTeam variable so that the call changes depending on which team was clicked.
这是静态的团队$ HTTP请求（我除了打破了URL，然后连接起来，以使其更清晰）：
This is the static team $http request (I've broken the URL apart and concatenated to make it clearer):
return $http.get(
'http://api.com/team/' + '16110' + '?Authorization=xxxx'
)
我要的 16110 部分，它指的是一个团队，是一个在 whichTeam 变量，允许它拉在正确的各个团队的数据，但我不知道如何写这个（或实际上如果可能的话）。
I want the 16110 part, which refers to ONE team, to be a the whichTeam variable, allowing it to pull in the correct individual team data, but I don't know how to write this (or indeed if it's possible).
我希望我已经清楚 - 高兴，如果需要进一步澄清。先谢谢了。
I hope I've been clear - happy to clarify further if needed. Thanks in advance.
推荐答案
请工厂：
app.factory("DataService", ["$http", function($http) {
return {
getTeamDetailsById: function(teamId) {
return $http.get('path/to/api' + teamId + '?Auth=xxxx')
}
};
}]);
使用它的控制器：
app.controller("MainCtrl", ["$scope", "DataService", function($scope, DataService) {
$scope.teamDetails = {};
$scope.getTeamDetailsById = function(event, teamId) {
//prevent click navigation
event.preventDefault();
//call factory service
DataService.getTeamDetailsById(teamId).then(function(response) {
//success callback
$scope.teamDetails = response.data;
}, function(response) {
//an error has occurred
});
}
}]);
在 NG-重复元素：
<div ng-repeat="team in teams">
<a href ng-click="getTeamDetailsById($event, team.team_id)">{{team.team_name}}</a>
</div>
以上假设你只有一个状态，并存储只有一个控制器。如果你要使用不同的状态usving $ stateProvider ，那么你就必须使用参数，通过使用的UI-SREF 并传递团队ID。
The above assumes you have only one state and are storing in only one controller. If you want to use different states usving $stateProvider, then you'd have to use parameters, by making use of ui-sref and passing in team Id.
如果你确实使用 $州和参数，做到这一点：
If indeed you are using $states and parameters, do this:
<a href ng-click="goToState($event, team.team_id)">{{ team.team_name }}</a>
$scope.goToState = function(e, teamId) {
$state.go("teamDetailsState", { "teamId": teamId });
}
