jQuery將變量推入數組

我有2個獨立的代碼，需要將它們組合在一起工作，一個是3個滑塊，您可以選擇不同的值並根據所選值獲取價格。其他代碼需要將這些值添加到數組中。目前，ram，diskspace和cpu值被硬編碼填充，但我需要它來獲取滑塊的值並使用它。滑塊值被保存到自己的值，但我不知道如何使它們一起工作。這是我目前所面對的購物車，其中值插入到了：jQuery將變量推入數組

$(".add-to-cart").click(function(event){ 
    event.preventDefault(); // prevents the links from doing their default behaviour 
    var name = $(this).attr("data-name"); 
    var price = Number($(this).attr("data-price")); //so this needs to be the totalPrice from the sliders fiddle 
    var ram = Number($(this).attr("data-ram"));// this needs to be the ram from the sliders fiddle 
    var diskSpace =Number($(this).attr("data-diskSpace"));// this needs to be the diskSpace from the sliders fiddle 
    var cpu = Number($(this).attr("data-cpu"));// this needs to be the cpu from the sliders fiddle 
    addItemToCart(name,price,1,ram,diskSpace,cpu); 
    displayCart(); 
}); 



var cart = []; 
var Item = function (name,price,quantity,ram,diskSpace,cpu){ 
    this.name = name; 
    this.price = price; 
    this.quantity = quantity; 
    this.ram = ram; 
    this.diskSpace = diskSpace; 
    this.cpu = cpu; 
}; 

//addItemToCart(name,price,quantity) 

function addItemToCart(name,price,quantity,ram,diskSpace,cpu){ 
for (var i in cart){ 
    if(cart[i].name === name){ 
     cart[i].quantity +=quantity; 
     saveCart(); 
     return; 
    } 

} 
    var item = new Item(name,price,quantity,ram,diskSpace,cpu); 
    cart.push(item); 

}

和滑塊功能：

<div class="wrapper"> 
    <input class="slider" id="ram" data-slider-id='ex1Slider' type="text" data-slider-min="0" data-slider-max="10" data-slider-step="1" /> 
     <hr /> 

    <input class="slider" id="diskSpace" data-slider-id='ex1Slider2' type="text" data-slider-min="0" data-slider-max="100" data-slider-step="10" /> 
     <hr /> 
     <input class="slider" id="cpu" data-slider-id='ex1Slider3' type="text" data-slider-min="0" data-slider-max="4" data-slider-step="1" /> 

     <hr /> 



    </div> 
    Prijs: 
<div id = "prijs"> 
</div> 


var minSliderValue = $("#ram").data("slider-min"); 
var maxSliderValue = $("#ram").data("slider-max"); 

$('#ram').slider({ 
    value : 0, 
    formatter: function(value) { 
     return 'RAM: ' + value + 'GB'; 
    } 
}); 

$('#diskSpace').slider({ 
    value : 0, 
    formatter: function(value) { 
     return 'Disk Space: ' + value + 'GB'; 
    } 
}); 

$('#cpu').slider({ 
    value : 0, 
    formatter: function(value) { 
     return 'CPU : ' + value + ' Cores'; 
    } 
}); 

// If You want to change input text using slider handler 
$('.slider').on('slide', function(slider){ 

    var ram = $("#ram").val(); 
    var diskSpace = $("#diskSpace").val(); 
    var cpu = $("#cpu").val(); 
var totalPrice=(parseFloat(ram)*3.5 + parseFloat(diskSpace)*0.15+ parseFloat(cpu)*6.5).toFixed(2); 
    $("#prijs").html(totalPrice); 

});

如果這2碼中相同的文件，你可以很容易地得到的值：

$("#ram").val(); 
$("#cpu").val();

如果上述鱈魚e包含在與html相同的頁面中，我提到的代碼也可以工作。
