Why is the JSON Object returning as undefined?

This particular array.

var theObject = [{"id":"412","thn_akademik":"20152","id_prodi":"15301","kode_mk":"20038","tanggal":"23\/8\/2016","jam_1":"17:00\t","jam_2":"19:00\t","npm":"07150100190","flag1":"0","flag2":"0"},{"id":"558","thn_akademik":"20152","id_prodi":"15301","kode_mk":"20053","tanggal":"25\/8\/2016","jam_1":"17:00\t","jam_2":"19:00\t","npm":"07150100190","flag1":"0","flag2":"0"},{"id":"704","thn_akademik":"20152","id_prodi":"15301","kode_mk":"20052","tanggal":"30\/8\/2016","jam_1":"17:00\t","jam_2":"19:00\t","npm":"07150100190","flag1":"0","flag2":"0"},{"id":"850","thn_akademik":"20152","id_pro...
    
for (var i = 0; i < theObject.length; i++) { 
    alert(theObject[i].kode_mk);
}

It functions properly when tested on this fiddle link.

However, upon integration into my application, it returns undefined.

Does anyone have insight into why this may be happening?

Answer №1

Here we have a unique javascript object, not to be confused with a JSON object. It seems unclear what you mean by "But when i try in on my apps in return undefined.". Which specific app are you referring to?

If your application is fetching JSON data, remember to parse it before trying to iterate through it. For example:

var json = JSON.parse(JSON_HERE);

You can then proceed to iterate through the JSON object and access the value of kode_mk.

If you could provide some code snippets from your "app", that would be helpful. Please explain the functionality of your app and how it retrieves the JSON data.
