Hi Debabrata.
Thank you very responding.
Below is moy javascript snippet.
Javascript :
parseString.outputSchema = "dataMap:chararray";
function parseString(str) {
var result = {};
str.split('&').forEach(function(splitString) {
var arr = splitString.split('=');
arr[1] && (result[arr[0]] = arr[1]);
//var oldJSONStringify = JSON.stringify;
//console.log(oldJSONStringify(result));
return result;
//return oldJSONStringify(result);
});
}
