Hi,

how does it work for you? can you please help?

Hello KKrish,

I guess you dont need to have dependencies with help of javascript eval method, json parsing is readily supported in the box.

so you can try something like:

var jsonObject = eval('(' + testToparse + ')');

which will return a list or a dict and than you can iterate over that to get what you want.

Let me know if you need a working example. :-)

Will it work on emulator?

getting error on on qtSDK 1.2 emulator "Result of expression 'jsonObject.flux' [undefined] is not an object"

[gaba88]

can you show the code you are trying its working good on my side and you dont need to import anything new.

xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState === 4) {
if (xmlhttp.status === 200) {
var jsonObject = eval('(' + xmlhttp.responseText + ')');
for ( var index in jsonObject.flux.all )
{
console.log(jsonObject.flux.all[index].data["title"]);
console.log(jsonObject.flux.all[index].data["content"]);
}
} else {
console.log("responseText", xmlhttp.responseText);
}
}
}

it is done. just going through with the json document and how we can access the element from json object.

QML includes a "JSON" parser. Instead of using eval use JSON.parse.... No need to include or import anything...
