vue.js getting started not working
Question
I'm trying out vue.js for the first time, and a beginner javascript programmer. I'm going through the vue.js getting started page
My html code is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>React Tutorial</title>
<script src="bower_components/vue/dist/vue.js"></script>
<script src="js/myVue.js"></script>
</head>
<body>
<div id="demo">
<h1>{{title | uppercase}}</h1>
<ul>
<li
v-for="todos"
v-on="click: done = !done"
class="{{done ? 'done' : ''}}">
{{content}}
</li>
</ul>
</div>
</body>
</html>
and myVue.js file is
window.onload = function () {
var demo = new Vue({
el: '#demo',
data: {
title: 'todos',
todos: [
{
done: true,
content: 'Learn JavaScript'
},
{
done: false,
content: 'Learn Vue.js'
}
]
}
});
}
The Getting started code is old because v-repeat has beeen depreciated and replaced with v-for. When I use v-for I get the warning "alias is required in v-for". I also get an uncaught typeError "cannot read property "create" of undefined.
The JSFiddle code does not work either.

v-for requires alias means you have to name the variable in your for loop, like so:
<li
v-for="todo in todos"
@click="todo.done = !todo.done"
v-bind:class="{'done' : todo.done}">
{{todo.content}}
</li>
