I created a Regex which allows to capture the parameters of a function.
The parameters are separated by the character ,
You can have the character , inside a parameter like 'lorem, impum'
The regex returns only the last match.
My Regex :
\s*(\'.+\'|\".+\"|[^,]+)?(?:\s*,?\s*(\'.+\'|\".+\"|[^,]+))*
function parametes
111111111111,'222222222',"33333333333333"
LInk to regex exemple : https://regex101.com/r/fdRJ92/2
var rx = /(?:^|,)\s*((('|").*?(?<!\\)(\3))|(\d?\.?\d+))/g;
var str = `"21312\\'\\"3123\\"", 111111111111,'222222\\'222',"333333333,33333", 1234, .123, 0.3, '454'`;
var match;
while (match = rx.exec(str)) console.log(match[1]);
Output
"21312\'\"3123\""
111111111111
'222222\'222'
"333333333,33333"
1234
.123
0.3
'454'
