Javascript shared variables between QML

Djeff

Hello,

I have a first js file that get a list and fill a libraryModel after a Json request.

When the user click on a row in the TableView the js file will send it to another js file that it set as a library (as I saw on internet, this ".pragma library" allow me to shared variable)

But when I try to access to a variable in the library js file, I didnt receive what i wanted.

My library js file :

.pragma library

var index;

function setIndex(r){
    index = r;
    console.log("set row index : "+index)
}

function getIndex(){
    console.log("return index js : "+index)
    return index
}

I got this on the console :
Click on my first QML file = qml: set row index : 1
Access to my next QML file = qml: return index js : undefined

Thank for your help

Hi,

How are you using js inside your second QML file? I think in your case you need something like this:

import "path_to_your_js_file" as SharedLib
//......
Component.onCompleted: {
     console.log(SharedLib.index);
}
//.....

By the way you don't need setter and getter methods because your variable is public.

@shav That's exactly what I have but it doesnt work

Why you use JS for sharing variable between qml files? You can use id of cml items inside your qml files. For example if you have qml file like this:

import QtQuick 2.0

Item {
    id: item1
    property var prop1: ({key1: "value1"})

    SomeAnotherQml {
    }
}

SomeAnotherQml.qml implementation:

import QtQuick 2.0

Item {
    id: secondQmlItem

    property var prop2: null

    Component.onCompleted: {
        console.log("item1: "+JSON.stringyfire(item1.prop1));
        console.log("prop2: "+JSON.stringyfire(prop2));
    }
}

In console you must see the value of prop1 from item1 also you can add property to your second qml file and send it like this:

SomeAnotherQml {
    prop2: item1.prop1
}

About your solution, I tried it before, many times, but I dont really know how to use it in my case and because I have to finish the project quickly, I dont have time to understand how use it.
