Regex to split a long expressions string into an array of individual expressions

I have an expression string from Angular [ngClass] directive containing multiple expressions with their corresponding key separated by a comma.

'background_orange':row.columnname.split(',')[4] == 1,'red:color':test==='testname','yellow:color':test==='testname'

When I try to split the above expression string into an array of individual expression with their using the .split(',') function it is splitting the in between the individual expressions.

Code:

var temp = "'background_orange':row.columnname.split(',')[4] == 1,'red:color':test==='testname','yellow:color':test==='testname'";

var result = temp.split(',');
console.log(result);

Output:

["'background_orange':row.columnname.split('", "')[4] == 1", "'red:color':test==='testname'", "'yellow:color':test==='testname'"]

Expected Result:

["'background_orange':row.columnname.split(',')[4] == 1", "'red:color':test==='testname'", "'yellow:color':test==='testname'"]

I tried to build regex to extract the individual expression but able to only extract the expression keys with the below regex

Regex:

'\b(.+?)':

What would be a regex to extract the above mentioned expected pattern

The following regex splits your string at , but ignores all , inside strings between " or ':

var temp = "'background_orange':row.columnname.split(',')[4] == 1,'red:color':test==='testname','yellow:color':test==='testname'";
var r = /(('[^']*')|("[^"]*")|[^,])+/g

var result = temp.match(r)
console.log(result);

Each match is a non-empty sequence of:

1. ('[^']*') letters not being ' between '
2. ("[^"]*") same as above with "
3. [^,] a char not being ,
