Thanks. I saw that it didn't work for me, so I hacked it until it did.
Below is the end result that actually works:
------------
importQtQuick2.3
importQtQml.Models2.1
import "jsonpath.js"as JSONPath
ListModel{
property string source: ""
property string json: ""
property var object:[]
property string query: ""
onSourceChanged:{
var xhr= new XMLHttpRequest;
xhr.open("GET", source);
xhr.onreadystatechange= function(){
if( xhr.readyState== XMLHttpRequest.DONE)
json= JSON.parse(xhr.responseText);
}
xhr.send();
}
onJsonChanged:{
object= JSON.parse(json);
updateJSONModel(true)
}
onObjectChanged: updateJSONModel()
onQueryChanged: updateJSONModel()
function updateJSONModel(){
clear();
var objectArray= objectArray= JSONPath.jsonPath(object, query);
for( var key in objectArray){
var jo= objectArray[key];
append( jo);
console.debug("JSONModel: append", JSON.stringify(jo))
}
}
}

escreveu:I get back from a Ajax a JSON object with a 'table' from a web query:
[
{id: 1, "category":"1", value:"1"},
{id: 2, "category":"1", value:"2"},
{id: 3, "category":"2", value:"3"},
...
]
What is the easiest way to convert the array to ListElements?
Up to this point, I was copying data using ListModel.append() but I was hoping
there was an implicit conversion:
listModel = rows; // where rows = [... the array above... ]
I was also looking for a way to create a model of the distinct values of
category. I realize there are sections within a ListView, but I want an actual
model.
THanks.
