Question about string segmentation using a javascript-Regular Expression

To split the string "1, 2, & #039; 3, 4 & #039;, 5", the result is [& #039; 1 & #039 ;, & #039; 2 & #039;, '','', '3, 4', & #039; 5 & #039;] ask me how to write a regular expression that I implemented using regular expressions. php code: {code ...} result :... to split the string ", '3, 4', 5", the result is ['1', '2', '','', '3, 4', '5']
Ask how to write a regular expression

========================================================== ================================
Php code is implemented by myself using regular expressions:

var_dump(preg_split("/[,]?'([^']+)'[,]?|[,]+?/", "1,2,6,7,,'3,4',5,8,9", 0, PREG_SPLIT_DELIM_CAPTURE));

Result:

array(9) {  [0]=>  string(1) "1"  [1]=>  string(1) "2"  [2]=>  string(1) "6"  [3]=>  string(1) "7"  [4]=>  string(0) ""  [5]=>  string(3) "3,4"  [6]=>  string(1) "5"  [7]=>  string(1) "8"  [8]=>  string(1) "9"}

I wonder if there is any problem.

The regular expression is not used, but this problem can be used.split()

var str = "1,2,,,'3,4',5";str.split(",");

  = 0; $i--) {        $result[$i] = trim($result[$i], "'");    }    var_dump($result);

Result:

array(10) {     [0]=> string(1) "1"     [1]=> string(1) "2"     [2]=> string(1) "3"     [3]=> string(1) "4"     [4]=> string(1) "5"     [5]=> string(1) "6"     [6]=> string(0) ""     [7]=> string(0) ""    [8]=> string(0) "3,4"    [9]=> string(4) "2333" }

It can be simplified and modified.

(Not the simplest answer.

Provide an idea:

Var str = ", '3, 4', 5"; // use the regular expression to replace ',' in '3, 4' with other characters, for example, '*', then 'split ', then check' * 'in each element, and change it back to var temp = str. replace (/'(\ w) +, (\ w) +'/, '$1*$2 '). split (','); str = temp. map (function (n) {return n. replace (/\*/,',');});

Hope to help ~ :)
