[Vuejs]-Example works in js-fiddle but not in self-made page

The Problem is the Version of Vue JS you are using. the one you mentioned here is different and the one you are using in jsfiddle is different.

Please remove the one u mentioned here and add the following.

<script type="text/javascript" src="https://unpkg.com/vue@2.0.3/dist/vue.js"></script>

It will work fine.
