|
|
|
* Splits a string into an array of strings using a regex or string
|

* separator. Matches of the separator are not included in the result array.
|
|
|
* However, if `separator` is a regex that contains capturing groups,
|
|
|
* backreferences are spliced into the result each time `separator` is
|
|
|
* matched. Fixes browser bugs compared to the native
|
|
|
* `String.prototype.split` and can be used reliably cross-browser.
|
|
|
* @param {String} str String to split.
|
|
|
* @param {RegExp|String} separator Regex or string to use for separating
|
|
|
* the string.
|
|
|
* @param {Number} [limit] Maximum number of items to include in the result
|
|
|
* array.
|
|
|
* @returns {Array} Array of substrings.
|
|
|
* @example
|
|
|
*
|
|
|
* // Basic use
|
|
|
* regex_split('a b c d', ' ');
|
|
|
* // -> ['a', 'b', 'c', 'd']
|
|
|
*
|
|
|
* // With limit
|
|
|
* regex_split('a b c d', ' ', 2);
|
|
|
* // -> ['a', 'b']
|
|
|
*
|
|
|
* // Backreferences in result array
|
|
|
* regex_split('..word1 word2..', /([a-z]+)(\d+)/i);
|
