每次调用“for {}”语句时添加数字

Question

我在这样的函数中有一个for语句：

for(i=0;i<=nc;i++){
var nd = //how many times this for statement has run+1
//if the for statement runs for the first time nd would be 1, second time nd would be 2, the for statement will run a total of "nc" times
this.id=nd }

我将如何实现这一目标？

Answer 1

你是说那个意思吗？

for(i=0;i<=nc;i++){
   var nd = i+1;
   this.id=nd;
}

Answer 2

我不知道你想要用什么来实现

for(i=0;i<=nc;i++)
{
   this.id = i+1; 
}

Answer 3

在函数

之外声明nd

var nd = 0;
function...
    nd++;
    this.id = nd;
