我有一个由我的自定义指令组成的按钮,一旦用户点击它就会进入控制器中的$scope.countClicker
,它将计算按钮被点击的次数。单击它的次数会将它将传递到的城市名称与数据工厂相关联。然后,从数据工厂的数据中,它将创建一个面板,如directive.js
我的问题是,一旦我点击多次,所有应该是唯一的表达式都会变成相同的。例如,$ scope.name3应仅显示" Osaka",但前面的3个面板都应该具有来自my for循环的唯一ID($ scope.name0,$ scope.name1,$ scope.name2)所有人都有#34;大阪"作为他们的头衔。我最初计划点击次数可以用作唯一ID,因此每个面板不会相互冲突,但出于某种原因,它是。
如果有人可以请帮助指出为什么会发生这种情况,我将不胜感激。谢谢!
directive.js :
app.directive('addbuttonsbutton', function() {
return {
restrict: "A",
template: "<md-button addbuttons ng-click='clickCounter()' class='md-fab md-mini'>+</md-button>"
}
});
//Directive for adding buttons on click that show an alert on click
app.directive('addbuttons', function($compile) {
return function(scope, element, attrs) {
element.bind("click", function() {
scope.count++;
var counter = scope.count;
console.log('this is scope count' + scope.count);
angular.element(document.getElementById('space-for-buttons')).prepend($compile( //adding a panel to my view
"<div class= panel>" +
"<h3 id=title" + scope.count + ">{{name" + scope.count + "| uppercase}}</h3><br>" +
"<i ng-class=weatherClass id=icon></i>" +
"<h3 id= temp >{{fTemp" + scope.count + " | uppercase}}</h3>" +
"<p style= 'color: #FAFAFA;' >{{description" + scope.count + "| uppercase}}</p>" +
"<p>{{location}}</p><br>" +
"<div id= wrapper ><div id= first ><i id= smallIcons class= 'wi wi-horizon-alt' ></i>" +
"<p id= eventID >SUNRISE</p><p id= subID >{{formattedSunrise" + scope.count + "}}</p></div>" +
"<div id= second ><i class= 'wi wi-strong-wind' id= smallIcons ></i>" +
"<p id= eventID >WIND</p><p id= subID >{{speed" + scope.count + "}}</p></div>" +
"<div id= third ><i class= 'wi wi-humidity' id= smallIcons ></i>" +
"<p id= eventID >HUMIDITY</p><p id= subID >{{humidity}}</p></div></div></div>")(scope));
});
};
});
控制器:
var app = angular.module('weatherApp.controllers', []);
app.controller('weatherCtrl', ['$scope', 'Data',
function($scope, Data) {
$scope.count = -1;
$scope.city = 'Berkeley';
var cityCounting = 0;
var counter = 0;
var cities = [
'Sydney, AU',
'Melbourne, AU',
'Tokyo',
'Osaka',
'Seoul',
'Hong Kong',
'London',
'Amsterdam',
'Berlin',
'Paris',
'Barcelona',
'New York',
'Dubai',
'Antarctica'
];
$scope.clickCounter = function(){
cityCounting = counter++;
$scope.city = cities[cityCounting];
console.log($scope.city);
console.log(cityCounting);
Data.getApps($scope.city).then(function(data) {
for (var i = 0; i < 14; i++) {
$scope.data = data;
$scope['name' + i] = data.name;
$scope['temp'+i] = data.main.temp;
$scope['fTemp' + i ] = ($scope['temp' + i] * (9 / 5) - 459.67).toFixed(1) + " °F";
}//end of for loop
}); end of Data service
}//end of controller

我意识到我的错误是for循环。在for循环中,它迭代了14次,因此$ scope.name [0-13]和所有其他变量都是每次点击触发,这就是所有面板都相同的原因。
但是在Vivz的帮助下,我放弃了for循环并使用了我的&#34; cityCounter&#34;变量而不是。

您可以移除for循环,它会通过点击次数帮助将相同的数据重新分配给每个变量。
$scope['name' + cityCounting] = data.name;
$scope['temp'+cityCounting] = data.main.temp;
$scope['fTemp' + cityCounting] = ($scope['temp' + cityCounting] * (9 / 5) - 459.67).toFixed(1) + " °F";
