The split () method can use the sub-string of the string as the separator to split the string into a string array and return this array.

Note: The substring used as the delimiter does not become part of the elements of the returned array or a member of the array element.

This section only describes how to use common characters as separators. For more information about using regular expressions as separators, see section 1 of the Regular Expression split () function.

Syntax structure:

The Code is as follows:

StringObject. split (separator, limit)

Parameter List:

Parameters	Description
Separator	Required. The substring used to split the string. Note: If this parameter is an empty string "", each character in the stringObject will be split.
Limit	Optional. Sets the number of times the string is split. If this parameter is omitted, the number of splits is not limited.

Note: If this parameter is an empty string "", each character in the stringObject will be split.

Limit is optional. Sets the number of times the string is split. If this parameter is omitted, the number of splits is not limited.

Instance code:

The Code is as follows:

Var a = "a, B, c, d, e ";
Console. log (a. split (","));

Use the substring "," as the separator to separate the string. This separator does not become part of an array element or a member of an array element. Output result: a, B, c, d, e.

The Code is as follows:

Var a = "a, B, c, d, e ";
Console. log (a. split (",", 2 ));

Limit the number of times the string is split, that is, limit the number of dimensions of the returned array. Output result: 2.

The Code is as follows:

Var a = "a, B, c, d, e ";
Console. log (a. split (""));

If an empty string is used as the separator, each character in the string is separated. Output result: a, B, c, d, and e.
