在JAVASCRIPT中查找拆分字符串的长度

Question

I have split a string into an array in JAVASCRIPT using the split() method and now I want to find the length of that array. But I couldn't. Each time that I ask for the length, the answer is always 1.

 var name = "AlanTuring"; var splitName =[]; splitName.push(name.split("")); var length =splitName.length; console.log(length); 

Answer 1

You need to remove push. it will works.

const name = "AlanTuring";
const splitName = name.split("");
const length = splitName.length;
console.log(length);

Answer 2

The line

splitName.push(name.split(""));

is splitting your string, then push ing the entire split array as a single element into another array.

The result is that splitName will be an array of arrays, like this:

[
  ["A", "l", "a", "n", "T", "u", "r", "i", "n", "g"]
]

Try

var name = "AlanTuring";
var splitName = name.split("");
var length = splitName.length;
console.log(length);

Answer 3

Use this instead

 var name = "AlanTuring"; var splitName = name.split(""); var length =splitName.length; console.log(length); 

Answer 4

string.split(""); returns an array that you need. You need not store the result and then push it in another array. This will suffice -:

  var name = "AlanTuring"; var splitArr = name.split(""); console.log(splitArr.length); 

Answer 5

Dont need to push. Because push push entire split array as a single element into the array. So it displays count 1.

 var name = "AlanTuring"; var splitName =[]; splitName =name.split(""); var length =splitName.length; console.log(length); 

Answer 6

如果您唯一的目的是获取字符串中的字符数，则只需使用String.prototype.length

 console.log("AlanTuring".length) 

Answer 7

Why don't you use String constructor function.

var splitName = new String(name);

Output like this
