A port of underscore.js to Qt/QML. The original Underscore. js will attach _ object to this object , but in QML we cannot add global object. Please refer to: http://doc.qt.io/qt-5/qtqml-javascript-hostenvironment.html#javascript-environment-restrictions

In this port, we attach _ object to the global object Qt, and then you could use all the underscore.js function in your QML.

import "underscore.js" as Underscore
Item
{
...
enabled: Qt._.every([inptBoxIP, inptBoxUser, inptBoxPassword],
                                      function f(e) {
                                        return e.text !== ""
                                      })
...
}
