AngularJS中获取被点击元素数据的值

如何data-attr在 Angularjs 中获取 html5值，并在同一类单击中单击相同的功能。

就像在 jquery 中我们点击一些类元素并获取当前元素 data-num。

我必须以有角度的方式实现这一点。

如何让多类元素点击并获取当前数据值（$this）？

<html ng-app="myApp">
    <head></head>
    <body ng-controller="mainController">
        <div ng-click="clicked()" data-num="1" class="same white">White</div>
        <div ng-click="clicked()" data-num="2" class="same green">Green</div>
        <div ng-click="clicked()" data-num="3" class="same red">Red</div>
        <div ng-click="clicked()" data-num="4" class="same white">White</div>
    </body>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"></script>
    <script>
        var myApp = angular.module('myApp',[]);
        myApp.controller('mainController',function($scope){
        $scope.clicked = function(){
        var id = angular.element('.same').scope();
        console.log(id);
        };
        });
    </script>
</html>

当改变复制变量的值时,它也改变angularjs中的主变量值

我处境很奇怪.我有一个对象数组,我使用angular.forEach来修改每个对象价格键值,但是当我在每个对象中更改它时,它也会更改主数组对象.

看看代码,你会明白我想说的.

var option_1_val = $scope.options.option_1_val;
        var option_2_val = $scope.options.option_2_val;
        console.log('genies',sc.genies);

        var new_arr = [];
        var each ;
        each = sc.genies;
        angular.forEach(each,function(val,key){
            var ob = {};
            ob = val;

            var priceA = angular.fromJson(ob.price);
            console.log('price',priceA);            

            var option = option_1_val.replace(" ","-")+","+option_2_val.replace(" ","-");
            console.log(option);

            ob.price = priceA[option];

            console.log(ob);
            new_arr.push(ob);
        });

option = 'Non-Vegetarian,' (after calculating)

sc.genies = [{"gs_id":"3","user_id":"25","service_id":"7","price":"{\"Vegetarian,Bengali\":\"200\",\"Vegetarian
,Chinese\":\"3100\",\"Vegetarian,Gujarati\":\"800\",\"Vegetarian,Italian\":\"100\",\"Vegetarian,Maharashtrian
\":\"100\",\"Vegetarian,Punjabi\":\"100\",\"Vegetarian,-South-Indian\":\"300\",\"Vegetarian,Thai\":\"100

现在,当我重复sc.genie,我已经在一个新的变量考虑它已经"每一个",然后我改变" 价格每个数组未定义但"键怪点,当我在价格SC的控制台值看.精灵也变成了"未定义".咦!

我希望你明白我的意思,请帮助我为什么会这样.

谢谢
