             }],

        }]
    }

}]

我的执行逻辑是：

一个。循环通过availableServices

湾查找每个服务子类型

℃。计算最高服务价格取决于minimumServiceCost，zonalMinimumServiceCost.minimumServiceCost和providerPrice.minimumServiceCost

d。 update providerAtServiceSubTypeLevel.calculatedMinServicePrice取决于上面计算的价格（如果providerPrice存在，那么将在更新期间考虑）

即这将继续用于所有可用的服务子类型

问题陈述

一个。在providerAtServiceSubTypeLevel.calculatedMinServicePrice的循环和更新期间，所有先前的元素都在更新最后一个值

只是为了模仿这里的问题是代码

for(var a=0;    a < zonedetails[0].availableServices.length; a++){

for(var b=0;    b < zonedetails[0].availableServices[a].serviceSubTypes.length; b++){

        for(var c=0;    c < zonedetails[0].availableServices[a].serviceSubTypes[b].providerAtServiceSubTypeLevel.length; c++){

                        console.log(" a  >> " + a + " b  >> " + b + " c  >> " + c);
                        zonedetails[0].availableServices[a].serviceSubTypes[b].providerAtServiceSubTypeLevel[c].calculatedMinServicePrice = a+b+c;
                        console.log("Change in first element >> " + zonedetails[0].availableServices[0].serviceSubTypes[0].providerAtServiceSubTypeLevel[0].calculatedMinServicePrice);

        }
}

}

这是输出

a＆gt;＆gt; 0 b>＆gt; 0 c>＆gt; 0 第一个元素的更改＆gt;＆gt; 0

a＆gt;＆gt; 0 b>＆gt; 0 c>＆gt; 1 第一个元素的更改＆gt;＆gt; 0

a＆gt;＆gt; 0 b>＆gt; 1 c>＆gt; 0 第一个元素的更改＆gt;＆gt; 1

a＆gt;＆gt; 0 b>＆gt; 1 c>＆gt; 1 第一个元素的更改＆gt;＆gt; 1

a＆gt;＆gt; 0 b>＆gt; 2 c>＆gt; 0 第一个元素的更改＆gt;＆gt; 2

a＆gt;＆gt; 0 b>＆gt; 2 c>＆gt; 1 第一个元素的更改＆gt;＆gt; 2

a＆gt;＆gt; 1b>＆gt; 0 c>＆gt; 0 第一个元素的更改＆gt;＆gt; 2

**我真的被困在这里，无法找到解决问题的任何线索或解决方案。请求任何帮助。感谢所有提前**

循环中的JavaScript属性更新，使用上一个值
