使用正则表达式“ [element1] [element2]”将字符串拆分为数组

Question

I have the following string:

var search = "[title|Asc][description|Desc]";

I'd like an array of:

[
    "title|Asc",
    "description|Desc"
]

I've tried various reg ex, but i just don't understand it enough.

var matches = search.split(/[^a-zA-Z0-9|]/);

Any chance i can have some help?

Answer 1

Use split and filter

var output = search.split(/[\[\]]+/).filter( s => s.length > 0 );

Demo

 var search = "[title|Asc][description|Desc]"; var output = search.split(/[\\[\\]]+/).filter( s => s.length > 0 ); console.log(output); 

Explanation

• split by /[\\[\\]]+/ , which is a one or more occurrence of character class of []

• filter out empty items.

Answer 2

Remove the first and last [ , ] and then split by ][

search.substring(1,search.length-1).split('][')

 var search = "[title|Asc][description|Desc]"; console.log(search.substring(1,search.length-1).split('][')) 

Answer 3

It is better to use a match instead of split to make sure we match string between [ and ] :

 const regex = /\\[([^\\]]*)\\]/g; const str = `[title|Asc][description|Desc]`; let m; while ((m = regex.exec(str)) !== null) { console.log(m[1]); }
