Qt 4.8 qml; javascript method does not work

[Dante Leoncini]

Hi. I 'm trying to use javascript methods but many do not work and found me a list of methods that do work in qt 4.8. Probe with simple standard codes and so do not understand that failure

I 'm trying to create a function that returns a string trimmed

the chain is for example: "file///E:/texto.txt"

I want it to be: "E:/texto.txt"

the function to use is:

property string texto = "file///E:/texto.txt"

function ubicacion(x) {
    var re = x;
    var ext = re.substring(7);
   return ext
}

ubicacion(texto)

this does not work. probe write a thousand different ways and with other similar methods. I also tried javascript basic methods but do not work .

use "substring", "substr", "slice", "length"

in the same code and use this code if it works:

function extension(x) {
    var re = /(?:\.([^.]+))?$/;
    var ext = re.exec(x)[1];
    return ext
}

and not know what else to try

He added : Accomplish make it work with a normal string . but when I use another string it does not work. try using " toString(x)" but gives nullo value

x = filePath
(filePath from Qt.labs.folderlistmodel 1.0)

achieve make it work like this:

property string archivo: null

function ubicacion(x) {
   archivo = x;
   return archivo.substr(8);
}
