jQuery substring

I have a key value pair something like this. this response comes back from the service in API.

var str = { "key1":"value1",..}

I need to use something lik this

for(var value in str) {

//I need to get only the value here. Eg: value1,value2 etc
}

how to get only value1 from this array using jquery sub string?

var str = { "key1":"value1","key2":"value2","key2":"value2"};

var keyItems,valItems;
for(key in str){
   keyItems.push(key);
   valItems.push(str[key]);
}

// keyItems is array of all keys
// valItems is array of all values.

If the response comes back as a set of (key, value) pairs, then you cannot really select the "first" value, because JSON objects do not have an order to their fields (different parsers may and probably will return the values in different order). You must know which key you want to access.

You can loop through an object (= key/value store) like this:

for (var key in items) {
    var value = items[key];
    // do things with key and value
}
