我有一個按照我的自定義指令形成的按鈕,一旦用戶點擊它,它將進入控制器中的$scope.countClicker,在那裏它將計算按鈕被點擊的次數。它被點擊的次數將把它將通過的城市名稱與數據工廠相關聯。然後從數據工廠的數據,它會創建一個面板,如指令所示.js自定義指令合併中的動態ng綁定

我的問題是,一旦我點擊不止一次,所有表達式應該是獨一無二的轉向是相同的。例如,$ scope.name3應該只顯示「Osaka」,但前面的3個面板都應該有我的for循環($ scope.name0,$ scope.name1,$ scope.name2)中的唯一ID,它們都有「Osaka」作爲他們的頭銜。我原本計劃點擊次數可以用作唯一ID,因此每個面板都不會相互衝突,但由於某種原因它是相互衝突的。

如果有人可以請幫忙指出爲什麼會發生這將不勝感激。謝謝!

directive.js

app.directive('addbuttonsbutton', function() { 
    return {

     template: "<md-button addbuttons ng-click='clickCounter()' class='md-fab md-mini'>+</md-button>" 
    }

您的控制檯在點擊按鈕時是否正確打印值? – Vivz

嗨@Vivz是的,我打印出我的點擊,他們是正確的 – hiswendy

@Vivz我意識到我的錯誤。這是for循環。當我打印for循環時,$ scope.name [0-13]全部打印出來,這就解釋了爲什麼面板具有相同的表達式。對於進入for循環和單擊迭代,您有任何建議,而不是讓for循環全部運行14次嗎? – hiswendy

您可以移除您的for循環,該循環將通過點擊數的幫助將相同的數據重新分配給每個變量。

$scope['name' + cityCounting] = data.name; 

$scope['temp'+cityCounting] = data.main.temp; 

$scope['fTemp' + cityCounting] = ($scope['temp' + cityCounting] * (9/5) - 459.67).toFixed(1) + " °F";

我意識到是在for循環我的錯誤。在for循環中,它迭代了14次,因此$ scope.name [0-13]和所有其他變量每次點擊觸發,這就是爲什麼所有面板都是相同的。

但是在Vivz的幫助下,我放棄了for循環並改用我的「cityCounter」變量。
