javascript - 如何在for循环中计算单词长度

Question

我有这样的循环数据:

for (var i = 0; i < 11;i++){
console.log(i); 
}

我的问题如何获得字长，所以我想得到这样的结果:

0 <-- this length is 1
1 <-- this length is 1
2 <-- this length is 1
3 <-- this length is 1
4 <-- this length is 1
5 <-- this length is 1
6 <-- this length is 1
7 <-- this length is 1
8 <-- this length is 1
9 <-- this length is 1
10 <-- this length is 2

Answer 1

您可以使用 toString() 将其解析为字符串函数，然后得到 length该字符串

for (var i = 0; i < 11;i++){
  console.log(i + ' <- this length is ' + i.toString().length); 
}
