如何在for循环

Question

算字长我有这样的循环数据：

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

我的问题是如何让字长，所以我希望做的结果是这样的：

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

您可以分析它字符串toString()功能，然后让length是string

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

的

Answer 2

这应该做的伎俩：

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

Answer 3

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