我如何使用正则表达式在不是字符的所有内容上拆分字符串

Question

How could I use vanilla javascript and regex to split on every character that is not a string? Example:

var src = "wer%55";

and have it return the array as

"wer","%","55"

Thanks!

Answer 1

You can use /(\\W+)/ for splitting and make sure to group \\W+ (1+ non-word characters) to be able to return it in the resulting array:

 var src = "wer%55"; console.log(src.split(/(\\W+)/)); // add filter(Boolean) to discard empty values from result array src = "wer%55#"; console.log(src.split(/(\\W+)/)); console.log(src.split(/(\\W+)/).filter(Boolean)); 

Answer 2

Split the string by the word boundary \\b :

 var src = "wer%55$$abc33"; console.log(src.split(/\\b/)); 

Or

Use String#match to get sequences of word / non word characters:

 var src = "wer%55$$abc33"; console.log(src.match(/\\w+|\\W+/g));
