I have a string like this
var str = "n,m,'klj,klp',ml,io"; // not the quotes arround klj,klp
I use javascripts .split() but it returns like this
n
m
klj
klp
ml
io
But I need it as below,not getting any idea
n
m
klj,klp
ml
io

Ugly, simple:
"n,m,'klj,klp',ml,io,'test,test,a,b','test',test".
match( /'[^']+'|[^,]+/g ).
map( function( x ) { return x.replace( /^'|'$/g, '' ) } );
Result:
["n", "m", "klj,klp", "ml", "io", "test,test,a,b", "test", "test"]
If this sample is from a CSV file, you have to look out for more gotchas.

Another solution:
var splitStrings = (function () {
var regex = /'.*?'/g;
return function (str) {
var results = [], matches;
matches = str.match(regex);
if (matches) {
results = matches.map(function (match) {
return match.substring(1, match.length-1);
});
}
return results.concat(str.replace(regex, '').split(',').filter(function (s) {
return s !== '';
}));
};
})();
It is a function wrapped inside a closure to keep the regex private.
console.log(splitStrings("n,m,'klj,klp',ml,io"));
// prints ["klj,klp", "n", "m", "ml", "io"]
The example from Zsolt's answer:
console.log(splitStrings("n,m,'klj,klp',ml,io,'test,test,a,b','test',test"));
// prints ["klj,klp", "test,test,a,b", "test", "n", "m", "ml", "io", "test"]
Note that the function doesn't preserve the order of strings.

If anyone wants to not hardcode values AS I have done,there is another way then only above match....map function work
add this incase you are refering from selectbox,textbox etc...
var newValue = $(".client option:selected").text();
if (/,/i.test(newValue)) {
newValue = "'" + newValue + "'";
}
newValue.match( /'[^']+'|[^,]+/g ).
map( function( x ) { return x.replace( /^'|'$/g, '' ) } );

C-like solution
function em_split(str) {
var ret = [], p0 = 0, p1 = 0, p2 = 0, pe = 0;
while ((p1 = str.indexOf(",",pe)) != -1) {
if ((p2 = str.indexOf("'",pe)) != -1 ) {
if (p2 < p1) {
if (p2==pe) {
pe = ((p2 = str.indexOf("'",p1)) == -1) ? p1 : p2;
} else pe = p1;
} else pe = p1;
} else { pe = p1; }
ret.push(str.substr(p0,pe-p0));
pe = (pe == p2) ? pe+2 : pe+1;
p0 = pe;
}
ret.push(str.substr(p0,str.length));
return ret;
}
example use:
console.log(em_split("n,m,'klj,klp',ml,io"));
console.log(em_split("n,m,'klj,klp,ml,io"));
console.log(em_split("n,m,klj,klp',ml,io"));
will return:
Array [ "n", "m", "'klj,klp", "ml", "io" ]
Array [ "n", "m", "'klj", "klp", "ml", "io" ]
Array [ "n", "m", "klj", "klp'", "ml", "io" ]

You can use Array.prototype.split() method with regex for this.
var str = "n,m,'klj,klp',nl,'klj,x,y,klp','klj,klp',ml,io";
var splits = str.split(/'([^']+)'|([^,]+)/);
var results = splits.filter(function(v){
if (v && v!== ",")
return true;
return false;
});
document.write("<br>Output: " + JSON.stringify(results));
.split()function.
