How to use my own javascript function in QML?-CodePudding

I'm trying to call my own function to add an image source. The code is similar to this:

function pics(){

        if (ident === "Nabil"){
           var source = "qrc:images/Plane1.png" ;
        }
          return source;
    }

    Image
    {
        id: myIDImage
        source: myIDImage.pics() //here I am calling my function
        x:        0
        y:        0
        width: 30
        height: 30
}

//Can anyone please tell me the way of calling my own function?

CodePudding user response：

You would do something like this:

import QtQuick 2.12

Item {
    function fibonacci(n){
        var arr = [0, 1];
        for (var i = 2; i < n   1; i  )
            arr.push(arr[i - 2]   arr[i -1]);

        return arr;
    }
    TapHandler {
        onTapped: console.log(fibonacci(10))
    }
}

So, you do not need to call pics on myIDImage.

source: pics()

Moreover, in your case, you could just do something like:

source: (ident === "Nabil") ? "qrc:images/Plane1.png" : ""
