Question

好的，所以我有一个javascript函数设置来添加一个ID为up的div并将其总计，并将值显示在顶部。嗯它的工作正常，但是由于它是多重身份，我对如何获得总数感到困惑！

function GetCost(ID) {
    var cost = $('#Cost'+ID).val();
    var income = $('#Income'+ID).val();
    var owned = $('#Own'+ID).val();
    var new_cost = number_format(cost * owned / 10 + 1000);
    $('#PropCost'+ID).html('Cost: $'+new_cost);
    $('#TotalIncome').html(number_format(income * owned));
}

你可以看到它带有Div加ID。那么这里有多个div的HTML。他们与不同的ID分开如：own1然后例如拥有2。

这里是收入部门。

<div id="Basic" align="center">Basic Properties: (Income: $<span id="TotalIncome">0</span>)</div>

那么，当我更改property1的表单时，它是如何成为onkeyup函数的。它将显示数学总计。但是，如果我更改了property2的表单，它将显示属性2的总数学数据。如何将它添加2并显示两者的总数？我将会有大约15种不同的价值，当你改变价值的时候，我对于该做什么感到困惑，请帮助!!谢谢！！要了解我正在谈论的内容，请访问以下网站：http://psychowars.net/addtrain/property_cost

我不确定你想要什么。假设您希望得到总数（所有收入*的总和）并将其放在#TotalIncome上，在这里（通过所有这些替换您的GetCost）：

//Just calculates. Doesn't affect UI
function getCostsById(ID) {
    var cost = $('#Cost'+ID).val();
    var income = $('#Income'+ID).val();
    var owned = $('#Own'+ID).val();
    var new_cost = cost * owned / 10 + 1000;        
    return {
       cost: cost,
       income: income,
       owned: owned,
       new_cost: new_cost
    };
}

//I assume total is sum of every income*owned
function getTotalCost(){
    var total = 0;
    for(var id=1; id<=10; id++){
        var costs = getCostsById(id)
        total += costs.income * costs.owned;
    }
    return total;
}

//This affects UI
function GetCost(ID){
    var costs = getCostsById(ID);    
    $('#PropCost'+ID).html('Cost: $'+number_format(costs.new_cost) );
    $('#TotalIncome').html(number_format(getTotalCost()));
}

#TotalIncome仅使用最近编辑过的财产的收入进行修订。在计算总数时，它还需要包括所有其他财产位置。只需修改计算的功能。

$('#TotalIncome').html((income * owned));

对此：

var sum = 0;
$('[id^="Own"]').each(function(){
    var id = $(this).attr('id');
    id = id.replace("Own","");
    sum += (( $('#Income'+id).val())*$('#Own'+id).val())
});
$('#TotalIncome').html(sum);
