See my updated loop above for correct usage IMPORTANT: the method wont work in old old browsers - so if you plan to make your website available through some sort of time bending internet connection, this could be a problem! If you really are interested though, here is a support chart (which ticks all my boxes).

So I edited the code as per my requirement. And here are the changes: It will save the id number from the response into the environment variable. var jsonData = (responseBody); for (var i = 0; i <; i++) var counter = [i]; tEnvironmentVariable("schID", );} ElChiniNet 2, 578 2 gold badges 17 silver badges 24 bronze badges answered Jul 25 '18 at 13:21 The answer with the higher vote has a mistake. when I used it I find out it in line 3: I changed it to: var counter = jsonData[i]. counters; and it worked for me.

There are plenty of examples of this, and the JSON reader automatically parses the JSON message into the model you specified. There is no need to use basic Javascript when using ExtJs, everything is different, you should use the ExtJs ways to get everything right.

(unters[counter]. counter_name);} But as counters is an Array, you have to use a normal for-loop: for (var i=0; i<; i++) { answered Apr 3 '12 at 11:00 Bergi Bergi 502k 104 gold badges 804 silver badges 1147 bronze badges "Sencha way" for interacting with server data is setting up an proxied by a (in this case) furnished with a (for JSON-encoded data, there are other readers available as well).
