There are multiple a tags (a tag 1, a tag 2, a tag 3), and each button corresponds to different JSON data (JSON1, JSON2, JSON3). Please tell me how to set up when I click on the first a tag to load the corresponding JSON data?

Use ng-repeat to loop through multiple a tags.

<a class="itemx" id="{{data.id}}" ng-repeat="data in toploops" ui-sref="{{data.sref}}" ng-click="topBanner($event,$index)">
        <p class="image"><img ng-src="{{data.image}}"/></p>
        <h4>{{data.title}}</h4>
        <p>{{data.dec}}</p>
</a>

Then jump to the question target page. It is also looped out using ng-repeat. I just want to jump here on the previous page to get different json content.

<p class="card" ng-repeat="data in test">        
    <p class="item item-text-wrap">
        {{data.title}}
    </p>
    <p class="item-image">
        <img ng-repeat="x in data.image" ng-src="{{x}}"/>    
    </p>
</p>

Corresponding JSON file.

    "JSON0":[{
        "image":["img/001.jpg","img/002.jpg","img/026.jpg","img/014.jpg"],
        "title":"1234"
    }],
    "JSON1":[{
        "image":["img/019.jpg","img/013.jpg"],
        "title":"4567"
    }}],
    "JSON2":[{
        "image":["img/029.jpg","img/014.jpg"],
        "title":"78910"
    }]

Get JSON settings.

app.controller("content",function($scope,$http){
        $scope.$watch("viewContentLoaded",function(){
            $http({
            method:"GET",
            url:"./zt.json"
        }).then(function(response){
            //var test1 = response.data.zt.JSON0;
            //$scope.test = test1;
        
            $scope.topBanner = function($event,$index){
                var test1 = "response.data.zt.ztTopbanner"+$index;
                $scioe.test = test1;
        }
        })

At first, I wanted to dynamically change the path to obtain JSON. Who knew an error was reported. . Probably because dynamic modification is not allowed or something? Only specified values? ? I don’t quite understand either. So find the solution! Newbies are stuck here! I've been looking for a long time but can't find a way!
Please give me some advice! Trouble!
