Hi,
I solved it By myself
my solution is here

javscript

C#

var a = "";
        var temp="";
        function disp(str) {
            if (str.match("{(.*)}")[1].indexOf("}") != -1) {
                a = a + str.match("{(.*?)}")[1] + ";";
                temp = str.match("{(.*)}")[0].toString().replace(str.match("{(.*)}")[1].toString().substr(0, str.match("{(.*)}")[0].toString().indexOf("}")), "");
                disp(temp.substr(1));
            }
            else {
                a = a + temp.substr(1).match("{(.*?)}")[1];
            }
            return a.replace("{","").replace("}","");
        }

calling of function

JavaScript

var result=disp('User name {1234}hf{12}djfh{2212}')
alert(result);

it shows 1234;12;2212

Thank you,
happy Coding:)
