如何在split（）JavaScript中排除转义字符

Question

I am looking to ignore the characters inside the square brackets because it matches with my split parameters.

The string that i want to split is

var str = "K1.1.[Other] + K1.2A.[tcc + K*-=>]";
var split = str.split(/[+|,|*|/||>|<|=|-]+/);

I want the output as K1.1.[Other], K1.2A.[tcc + K*-=>] .

But this above code is including the characters inside square brackets which i don't want to consider. Any suggestion on how to solve this?

Answer 1

split by both plus and braces as well. then go through chunks and join everything between braces pairs.

But better not to use regexp at all for that.

Answer 2

Split on the following pattern: /\\+(?![^\\[]*\\])/

Explanation:

\\+ - A literal plus sign

(?! ... ) - Negative lookahead (don't match the previous character/group if it is followed by the contents of this block)

[^\\[]* - Any number of non-left-square-brackets

\\] - A literal right square bracket
