I have a result of type of:

EMailLabel: "Mailing address"
LogLabel: "User login"
LoginButton: "Enter the program"

And in order to manipulate this result by splinting it into pairs, I need to convert it into string using the following:

 function parse(str, separator) 
 var parsed = ;
 var pairs = 
 str.toString().split(separator);
 for (var i = 0, len = pairs.length, keyVal; i < len; ++i) 
 keyVal = pairs[i].split("=");
 if (keyVal[0]) 
 parsed[keyVal[0]] = keyVal[1];
 

return parsed;

But in the instruction:

str.toString().split(separator);

returns me the value of:

[object Object]: undefined

And of nothing is turned into string.

If I use the same instruction like that:

str.split(separator);

Threw me the error of:

Uncaught TypeError: str.split is not a function

And from what I've searched on the web I saw that I have to convert the str which is a Hashtable result into string.

I did that but unfortunately without any success

Is someone to help me on this issue?

  Could you clarify your "input" data and what you expect to get as "output" because now your function parse expects a string as input and returns a hash table(map, object). But in the title, you say that you want to convert from a hash table into a string.

Looks like you need something like this:

function parse(map, separator) 
 return Object.keys(map).reduce((data, key) => 
 data.push(`$key$separator "$map[key]"`);
 return data;
 , []).join('n');
