[SOLVED] How to read variables from another function
-
Hi all,
I have 2 javascript functions in 1 file and I call them from QML file.
@
function load() {
var euro = xml.get(0).lastRate;
console.log(euro); // returns 25.4750
}function read() {
console.log(euro); //returns undefined
}
@I call them here:
@
import QtQuick 1.0
import "XML.js" as Xmlhttp...
XmlListModel {
id: xml
source: "http://www.myxmlfile.xml"
query: "/CurrencyList"XmlRole { name: "lastRate"; query: "Currency[1]/Rate/LastRate/string()"} onStatusChanged: { if (xml.status == 1) { Xmlhttp.load(); Xmlhttp.read(); } } }
...
@Is it possible to read in read() function euro variable?

I very much doubt this. I am not a javascript guru but I believe scoping rules limit the euro variable to the scope in which it is declared. In this case that is function load().
You should move the declaration out of the function if you want to access it.

I think the proper way to do this would be like this:
[code]
function load() {
var euro = xml.get(0).lastRate;
console.log(euro); // returns 25.4750
return euro;
}function read(var euro) {
console.log(euro); //returns undefined
}
[/code]And then you can call them like so in the onStatusChanged:
[code]
var euro = Xmlhttp.load();
Xmlhttp.read(euro);
[/code] -
It's working! Thank you very much.
