在 AngularJS ng-repeat div 中使用 href [英] Use href in an AngularJS ng-repeat div

问题描述

我正在尝试在使用 ng-repeat 的 div 中插入一个 href 链接.这个 href 链接需要与每个用 ng-repeat 创建的 div 不同，它的值是 AngularJS $scope 变量的一部分.

这是我的JS代码:

var app = angular.module('test', []);app.controller('MainCtrl', function($scope) {var 数据库 = firebase.database();database.ref(`trips/${userid}/trips`).once('value')//将返回 `tripId` 中的所有照片对象.then(照片快照 => {var 行程 = [];photosSnap.forEach((trip) => {行程.push({tripKey:trip.key，旅行名称:trip.val().name,tripPhotoUrl: trip.val().photourl,tripBeginDate: ConvertDate(trip.val().begindate),tripEndDate: ConvertDate(trip.val().enddate)});});$scope.repeatData = 行程；//数组放入angular controller的作用域中，后面和ng-repeat一起使用//$scope.data = repeatData;//$scope.value = repeatData;//立即应用，否则看不到变化$scope.$apply();//返回控制台中的数组以检查值console.log($scope);}).catch(err => alert(err));});

HTML 代码的一次尝试:

<div id="usertripinfo" ng-repeat="repeatData 中的数据" 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}}

这段代码只是不允许我点击任何地方，我的光标只是变成了一个指针而已.

再次尝试 HTML 代码:

<a ng-repeat="repeatData 中的数据" 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}}
</a>

有了这个代码，我可以点击，但它把我带到file:///Users/Marc/firebase/trip.html，所以它缺少参数userid和tripid(userid是AngularJS之外的变量，而tripid是AngularJS 下的 data.tripKey $scope.repeatData)

解决方案

对我来说，您似乎把这个问题复杂化了.没有理由使用我可以看到的 onclick.我会把它改成这样的:

<a ng-repeat="repeatData 中的数据" 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}}
</a>

我也不认为您需要第二次 ng-repeat，除非您真的想复制每个锚点内的所有图像.

I'm trying to insert a href link inside a div that uses ng-repeat. This href link needs to be different from each div created with ng-repeat, its value being part of AngularJS $scope variable.

Here is my JS code:

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));

     });

One try of HTML code:

<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>

This code just doesn't let me click anywhere, my cursor just becomes a pointer and that's it.

A second try of HTML code:

<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>

With this code, I can click, but it brings me to file:///Users/Marc/firebase/trip.html, so it's lacking the parameters userid and tripid (userid being a variable outside AngularJS, and tripid being data.tripKey under AngularJS $scope.repeatData)

解决方案

It looks like you're overcomplicating this to me. There's no reason for using onclick that I can see. I'd change it to something like:

<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>

I also don't think you need the 2nd ng-repeat unless you really want to duplicate all of the images inside of each anchor.
