我对这段代码有疑问我对编程很新，不知道我做错了什么。当从web浏览器运行该函数时，它说对象是预期的，但是在我添加一些代码之前它已经工作了addveh并删除了
很抱歉，如果这是错误的发布地点

下次您使用js代码时，请使用类似jsbeautifier的格式进行格式化，这是我的两分钱：
var addveh - 重复声明
var删除 - 应该删除吗？ // Nabeel Sheikh看到了它
var决定 - 重复声明
var addloading - 重复声明
vehend - 未声明的全局变量？
vehandipt - 未声明的全局变量？
addandipt - 未声明的全局变量？
} - 未闭合的大括号
可疑： veh = + veh + + document.getElementById（'romcarval'+ i）.value;

答案 1 :(得分：0)
您有几个问题：
如上所述，您要两次声明（使用var）addveh。
您为addveh分配值0，您的下一个操作是：
addveh = addveh / 1000 * 5;
此时（一旦删除第二个错误的var），addveh将始终为零，因此结果总是为零，我想这不是你需要的？
