Question

我正在尝试在使用ng-repeat的div中插入href链接。此href链接需要与使用ng-repeat创建的每个div不同，其值是AngularJS $范围变量的一部分。

这是我的JS代码：

var app = angular.module('test', []);

app.controller('MainCtrl', function($scope) {
    var database = firebase.database();
    database.ref(`trips/${userid}/trips`).once('value') 


    // will return you all the photo objects inside the `tripId`

.then(photosSnap => {


var trips = [];
photosSnap.forEach((trip) => {
trips.push({
tripKey: trip.key,
tripName: trip.val().name,
tripPhotoUrl: trip.val().photourl,
tripBeginDate: ConvertDate(trip.val().begindate),
tripEndDate: ConvertDate(trip.val().enddate)
});
});
 $scope.repeatData = trips;

// the array is placed into the scope of angular controller, later used with ng-repeat

   // $scope.data = repeatData;
   // $scope.value = repeatData;

// apply immediatly, otherwise doesn't see the changes

    $scope.$apply();

// returns the array in the console to check values

    console.log($scope);
}).catch(err => alert(err));

     });

尝试HTML代码：

<div class="main" ng-app="test" ng-controller="MainCtrl">

<div id="usertripinfo" ng-repeat="data in repeatData" style="background-image: url({{data.tripPhotoUrl}}); height: 300px; width: 600px; cursor: pointer;" href="trip.html" onclick="location.href=this.href+'?userid='+userid+'&tripid='+data.tripKey;return false;">

{{data.tripName}}
{{data.tripKey}}
{{data.tripBeginDate}}
{{data.tripEndDate}}

    </div>

</div>

这段代码不让我点击任何地方，我的光标就变成了一个指针，就是这样。

HTML代码的第二次尝试：

<div class="main" ng-app="test" ng-controller="MainCtrl">

<a ng-repeat="data in repeatData" href="trip.html" onclick="location.href=this.href+'?userid='+userid+'&tripid='+data.tripKey;return false;">
    <div id="usertripinfo" ng-repeat="data in repeatData" style="background-image: url({{data.tripPhotoUrl}}); height: 300px; width: 600px; cursor: pointer;">

{{data.tripName}}
{{data.tripKey}}
{{data.tripBeginDate}}
{{data.tripEndDate}}

    </div>
    </a>

</div>

使用此代码，我可以单击，但它会将我带到file：///Users/Marc/firebase/trip.html，因此它缺少参数userid和tripid（userid是AngularJS之外的变量，而tripid是AngularJS $ scope.repeatData）下的data.tripKey

看起来你过于复杂了。没有理由使用我能看到的onclick。我将其更改为：

<div class="main" ng-app="test" ng-controller="MainCtrl">

<a ng-repeat="data in repeatData" href="trip.html?userid={{userid}}&tripid={{data.tripKey}}">
    <div id="usertripinfo" style="background-image: url({{data.tripPhotoUrl}}); height: 300px; width: 600px; cursor: pointer;">

{{data.tripName}}
{{data.tripKey}}
{{data.tripBeginDate}}
{{data.tripEndDate}}
    </div>
    </a>
</div>

除非你真的想要复制每个锚内的所有图像，否则我也不认为你需要第二次重复。
