在每组字符后分割一个字符串

Question

In Javascript, I want to split a string into several segments based on the content.

Each segment is a random set of character, and ends with a unicode superscript character.

An example string would be:

this⁵²is¹an³⁶⁻³⁵example²⁴string³¹

And the result would be:

this⁵²
is¹
an³⁶⁻³⁵
example²⁴
string³¹

Each group containing ¹²³⁴⁵⁶⁻ marks the end of each segment.

Answer 1

Use String#match() , like this:

var string = 'this⁵²is¹an³⁶⁻³⁵example²⁴string³¹';

// regex that looks for groups of characters
// containing first a sequence of characters not among '¹²³⁴⁵⁶⁻',
// then a sequence of character among '¹²³⁴⁵⁶⁻'
var regex = /([^¹²³⁴⁵⁶⁻]+[¹²³⁴⁵⁶⁻]+)/g;
var groups = string.match(regex);

console.log(groups);
// prints:
// [ 'this⁵²', 'is¹', 'an³⁶⁻³⁵', 'example²⁴', 'string³¹' ]
