parse values from javascript object

Question

I see there is a problem to get a String name from JSON object's name. I need to parse this kind on JSON response from server.

var response = {
 hopaopGmailsjIpW: {
 GmailsjIpW_totalEmails_count: 133,
 GmailsjIpW_state: 1
 },
 hopaopGmail4y4yu: {
 Gmail4y4yu_totalEmails_count: 156,
 Gmail4y4yu_state: 1
 }
}

It is not an Array, but the object with inner objects. i need to parse an inner ojects name and add additional values to each object.

i want be able to do something like this:

for(var i =0; i < response.length; i++){
 response[i].username = parseUsernameFromString(response[i]);
 response[i].service = parseServiceFromString(response[i]);
 response[i].id = parseIdString(response[i]);
}

(and also state for each task)

So the question is: What is the best way to make it?

UPDATE this is exactly what i have for now:

for(var key in response){
 if(stringContains(response[key], "Gmail")) { response[key].service = "Gmail";}
 console.log("task name: "+ response[key].service);
}
function stringContains(originalString, searchString){
 if(originalString.indexOf(searchString) > -1){
 return true
 }
 else return false;
}

• Quentin: Your first block of code is not JSON, nor is it JavaScript. You'd need to write a custom parser for it (start reading here). It would be better to fix the server so the response is actually JSON.
• user1935987: The thing is it is a request from some implementation of dataCache on server side, changing server part is too much work, doesn't worth. also i have this situation only in one place in my app.
• user1935987: right, comma is missing, sorry,
• JJJ: Are you asking how to loop through the object, or how to write the parseUsernameFromString etc functions? The question isn't very clear.
• T.J. Crowder: That structure is just truly, truly bizarre. It really needs fixing. The properties of the inner objects should have consistent names, for one. Basic principles, people.

Answer 1

For walking through Objects, you need to use for ... in loop.

The real problem is: There's a , missing in your code. See the fixed working snippet:

Snippet

var response_Parsed = {
 hopaopGmailsjIpW: {
 GmailsjIpW_totalEmails_count: 133,
 GmailsjIpW_state: 1,
 service: 'Gmail',
 username: 'hopaop',
 id: 'sjIpW'
 },
 hopaopGmail4y4yu: {
 Gmail4y4yu_totalEmails_count: 156,
 Gmail4y4yu_state: 1,
 service: 'Gmail',
 username: 'hopaop',
 id: '4y4yu'
 }
};
for (id in response_Parsed) {
 console.log("----");
 if (id.indexOf("Gmail") > -1) {
 console.log("We have Gmail: " + id);
 console.log("UniqueName: " + id.replace("hopaopGmail", ""));
 console.log("Username: " + response_Parsed[id].username);
 console.log("Email Count: " + response_Parsed[id][id.replace("hopaop", "") + "_totalEmails_count"]);
 }
 else
 console.log("We don't have Gmail: " + id);
}

And also the right way to enumerate the through the keys of the objects, is by using Object.keys.

• Praveen Kumar Purushothaman: Is there anything else I should add or correct to make this answer a better one?
• user1935987: i can't know the exact values of hopaopGmail4y4yu for example because it include generic ID. Yes, comma was missing.
• user1935987: sorry, but this is not the answer.
• T.J. Crowder: @user1935987: You just have to apply what Praveen showed you not just to the outermost object (as he has), but then also to the objects its properties refer to. It's just applying the same principle.
• user1935987: the problem was that i was parsing response[key] , but not the key

Answer 2

If the response is a String like you wrote, you should first parse the JSON-String into an Object (if you're using a library like jQuery, it's probably already a JSON, as this conversion is done by jQuery automatically):

var obj = JSON.parse(responseString);

Afterwards you may iterate through it like posted above:

for (var key in obj) {
 console.log("key", key, "value", obj[key]);
}

• Praveen Kumar Purushothaman: Afterwards you may iterate through it like posted above What's your answer good for then? :)
• MattDiMu: @PraveenKumar Yes, my answer was some second later, so i added this sentence. Still it contains the JSON.parse part.
• Praveen Kumar Purushothaman: @MattDiMu I was more interested on you removing that JSON Object. There's nothing like that. How do you say, "JavaScript Object Notation Object"? :D
