从一个控制器传递到另一个特定的数据 [英] Pass specific data from one controller to another
问题描述
我有一个列表。我要的是当我点击相关的只有的listItem数据显示,其中一个新的页面应该打开列表的项目之一。现在我使用的锚标记和的.config通过这样的数据:
<离子项目NG重复=田间场>
<一href=\"#detail/{{field.firstName}}/{{field.personNo}}/{{field.street}}/{{field.city}}/{{field.post$c$c}}\" ID =一个项目> < DIV的风格=宽度:100%;身高:100%>
{{field.firstName}}< BR>
{{field.personNo}}< / DIV>< / A>
< /离子项目>
和
的.config(['$ routeProvider',
功能($ routeProvider){
$ routeProvider。
什么时候('/', {
templateUrl:'模板/ mainpage.html })。
当('/细节/:名称/:无/:街/:城市/:交code',{
templateUrl:'模板/ details.html',
控制器:'detailctrl
})
}])
我不认为这是通过数据的有效途径。虽然我知道。服务,但我不能想出一个办法来传递数据具体到单击的项目。请提出一个更好的办法。谢谢
什么你看的是你确实想使用的服务(或工厂)的经典主详细模式。
先改变我会让你的code是给主路控制器,以及对细节的路线只有通过在personNo。
的.config(['$ routeProvider',函数($ routeProvider){
$ routeProvider。
什么时候('/', {
templateUrl:'模板/ mainpage.html',
控制器:'mainctrl
})。
当('/细节/:没有',{
templateUrl:'模板/ details.html',
控制器:'detailctrl
})
}])
接下来,让我们设置通过工厂PeopleService有两种方法。一,是GetPeople方法,得到数组中的所有的人并将其存储在私有变量之前通过解析HTTP $承诺。该GetPerson方法查找一个人通过personNo在私有变量。
.factory('PeopleService',['$ HTTP',函数($ HTTP){
变种人= [];
返回{
GetPeople:功能(){
$ http.get(路径/到/资源)。然后(功能(响应){
人=响应;
返回响应;
});
},
GetPerson:功能(personNo){
对于(i = 0; I< people.length;我++){
如果(人[I] .personNo == personNo){
返回的人[我]
}
}
}
}
}]);
接下来,我们mainctrl我们将要调用函数GetPeople
.controller(mainctrl,['PeopleService',函数(PeopleService){
PeopleService.GetPeople()。然后(功能(人){
$ scope.people =人;
});
}]);
最后,在我们的detailsctrl,我们将从$ routeParams得到personNo并用它来从我们的服务调用GetPerson方法。
<$p$p><$c$c>.controller(\"detailctrl\",['$routeParams','PeopleService',function($routeParams,PeopleService){VAR personNo = $ routeParams.no;
$ scope.person = PeopleService.GetPerson(personNo);
}]);
I have a list. What I want is when I click on one of the item of List a new page should open where the data related to only that listItem is displayed. Right now I am using anchor tag and .config to pass data like this:
<ion-item ng-repeat="field in fields">
<a href="#detail/{{field.firstName}}/{{field.personNo}}/{{field.street}}/{{field.city}}/{{field.postcode}}" id="a-item"> <div style="width:100%;height:100%" >
{{field.firstName}}<br>
{{field.personNo}} </div></a>
</ion-item>
And
.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'templates/mainpage.html'
}).
when('/detail/:name/:no/:street/:city/:postcode', {
templateUrl: 'templates/details.html',
controller: 'detailctrl'
})
}])
I don't think this is an effective way to pass data. Although I know about .service but I can't figure out a way to pass data specific to the item clicked. Please suggest a better way. Thanks
What you're looking at is the classic master detail pattern that you indeed would want to use a service (or factory) for.
First change I'll make to your code is giving the main route a controller, as well as for the details route only passing in the personNo.
.config(['$routeProvider',function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'templates/mainpage.html',
controller: 'mainctrl'
}).
when('/detail/:no', {
templateUrl: 'templates/details.html',
controller: 'detailctrl'
})
}])
Next, let's set up a "PeopleService" via a factory with two methods. One, is the GetPeople method which gets all the people in an array and resolves a promise via $http before storing it in a private variable. The GetPerson method looks up a person by personNo in that private variable.
.factory('PeopleService',['$http',function($http){
var people = [];
return {
GetPeople: function(){
$http.get("path/to/resource").then(function(response){
people = response;
return response;
});
},
GetPerson: function(personNo){
for(i=0;i<people.length;i++){
if(people[i].personNo == personNo){
return people[i];
}
}
}
}
}]);
Next, in our mainctrl we will want to call that GetPeople function.
.controller("mainctrl",['PeopleService',function(PeopleService){
PeopleService.GetPeople().then(function(people){
$scope.people = people;
});
}]);
Finally, in our detailsctrl, we will get the personNo from the $routeParams and use it to call the GetPerson method from our service.
.controller("detailctrl",['$routeParams','PeopleService',function($routeParams,PeopleService){
var personNo = $routeParams.no;
$scope.person = PeopleService.GetPerson(personNo);
}]);
