I have code which shows a button that says: "Import 3d model". There I wish to let the user select a 3ds/max/gsm 3d model to load and seen on the screen.
My problem is that i just don't know how to do that, can some one write a simple example of how to do that? i'm kind of stuck.. thanks for any help :)

You can't load direclty a 3DSMax model, you have to convert it to JSON, but I don't think you can did it directly on the client side. It's possible to send it to a server who did the conversion then client get back the model in JSON and you'll be able to read it (but you'll need a converter on the server).
I already looked for 3dsmax format to JSON directly but didn't found. Here are converters but they have to be installed in the soft, so you can export to fbx then JSON. https://github.com/mrdoob/three.js/tree/master/utils/converters
You can also look here an online converter. http://www.babylonjs.com/converter.html
And here there is some other converters but not sure it'll work with ThreeJS I don't try ^^ https://github.com/BabylonJS/Babylon.js/tree/master/Exporters
