在後退按鈕後導航視圖煎茶觸摸顯示

Question

我建立在煎茶觸摸的應用的舊值2.0

使用導航視圖

即時創建以升序數學測驗的號碼的排列IM

我的問題是，當我運行應用程序它工作正常，第一次，但是當我點擊後退按鈕和老化在同一視圖進入它顯示我的老字號

strenge的事情是，在按鈕上的文本新NU mbers出現，但是當我點擊按鈕，並獲取文本它顯示我的老字號

我的代碼

最有可能的，你可以使用顯示監聽器，在容器顯示時調用它。編寫你的邏輯來動態創建組件。或者，作爲另一種替代方案，您可以重置其中的標籤或其他組件數據。

listeners: { 
    show: function(list, opts){ 
     // code to reset your comp 
    } 
}
