I've just read all the thread, maybe it's better if I provide more details about what I'm doing. My current task is experimenting the compatibility of Qt5/QML JavaScript engine with the most popular JavaScript libraries (for example: jQuery, BackBoneJs, etc...). All these libraries need browser objects like "window", "document" etc... to work properly. I found the EnvJs library and this useful blog article written by Kent Hansen http://labs.qt.nokia.com/2011/03/10/say-hello-to-envjs-for-qtscript/ the only problem is that he doesn't provide a complete (ready to be built) code example and he probably tested this on Qt4 (while I have to use Qt5), so I wrote a Qt5 example from scratch, trying to follow the article advices, but it's not working. I've tried to use both QtScriptEngine and QJSEngine but it doesn't work. Basically: 1) I load the env.js content and I evaluate it: qse.evaluate(js, "js_errors.txt"); 2) I call the initializeEnvjsNatives(&qse); 3) from my main.qml I import the env.js file (I should not import it since I've already evaluated it with qse.evaluate(....) right? Anyway it doesn't work in both ways... import "env.js" as EnvJs 4) I try to use it in this way: console.log("document:", EnvJs.document); EnvJs.document.write("<p>Hello, JavaScript in QtScript!</p>"); and this is the error I always get: document: undefined file:///home/andrea/Documents/EnvjsTest/qml/EnvjsTest/main.qml:24: TypeError: Cannot call method 'write' of undefined If it can be useful for you to understand better, I think I can provide the complete source code (it's just a basic example, but at least it will save you lot of time if you want to give it a try).
