如何爲Cordova應用程序啓用本地存儲

我試圖將值存儲到混合應用程序的本地存儲中。當我在桌面Web瀏覽器中運行應用程序時，但是當我在Android設備上運行相同的應用程序時，我無法看到與Web瀏覽器中相同的輸出。我認爲它沒有保存在本地存儲中。如何爲Cordova應用程序啓用本地存儲

有沒有什麼辦法可以解決這個問題，還是我必須啓用本地存儲？

這裏是我的代碼：

function deductBalance(){ 
    var str; 
    var num_arr = []; 
    var elems = document.querySelectorAll('.cost-block-deduct'); 
    elems.forEach(function(el) { 
     var nums = el.options[el.selectedIndex].value; 
     num_arr.push(nums) 
    }); 
    console.log(num_arr); 
    var alvar1 = (Number.parseInt(num_arr.join(""))); 
    localStorage.setItem("deducted", alvar1); 
    window.location.href = "home.html" 
} 

function todaysExpenses(){ 
    document.getElementById("spent_points_today").innerHTML = localStorage.deducted ; 
    document.getElementById("earned_points_today").innerHTML = localStorage.balance; 
    document.getElementById("balance-remaining").innerHTML = localStorage.balance - localStorage.deducted; 
    document.getElementById("balance-remaining-month").innerHTML = localStorage.balance - localStorage.deducted; 
}

檢查，如果本地存儲由瀏覽器支持還是不支持。 try local2tool.setItem（「mod」，「do」）; alert（localStorage.removeItem（mod））; （e）{ } catch（e）{ alert（「No」）; } – developerCK

你必須使用localStorage.getItem（）功能

，或者的localStorage [ 「扣除」]

function todaysExpenses(){ 
    var deducted = parseFloat(localStorage.getItem("deducted")); 
    var balance = parseFloat(localStorage.getItem("balance")); 
    document.getElementById("spent_points_today").innerHTML = deducted; 
    document.getElementById("earned_points_today").innerHTML = balance; 
    document.getElementById("balance-remaining").innerHTML = (balance - deducted); 
    document.getElementById("balance-remaining-month").innerHTML = (balance - deducted); 
}
