I'm trying a demo on vuejs. Now I want the html title to bind a vm field.

The below is what I tried:

index.html

<!DOCTYPE html>
<html id="html">
<head>
    <title>{{ hello }}</title>
    <script src="lib/requirejs/require.min.js" data-main="app"></script>
</head>
<body>
{{ hello }}
<input v-model="hello" title="hello" />
</body>
</html>

app.js

define([
    'jquery', 'vue'
], function ($, Vue) {
    var vm = new Vue({
        el: 'html',
        data: {
            hello: 'Hello world'
        }
    });
});

But the title seemed not bounded, how to make it work?

You can do it with 1 line in the App.vue file, like this:

<script>
    export default {
        name: 'app',
        created () {
            document.title = "Look Ma!";
        }
    }
</script>

Or change the <title> tag content in public/index.html

<!DOCTYPE html>
<html>
  <head>
    <title>Look Ma!</title> <!- ------ Here ->
  </head>
...

As I prefer to set the <title> from the view part, there are essentially two ways to solve it.

Use an existing Component

For example, vue-headful:

Install

npm i vue-headful

import Vue from 'vue';
import vueHeadful from 'vue-headful';

Vue.component('vue-headful', vueHeadful);

new Vue({
    // your configuration
});

And then use the vue-headful component in every of your views:

<template>
    <div>
        <vue-headful
            title="Title from vue-headful"
            description="Description from vue-headful"
        />
    </div>
</template>

Note that vue-headful not only supports the title, but also several meta tags and the document language.

Create your own Component

Create a vue file containing:

<script>
    export default {
        name: 'vue-title',
        props: ['title'],
        created () {
            document.title = this.title;
        },
        watch: {
            title () {
                // only used when the title changes after page load
                document.title = this.title;
            }
        },
        render () {
        },
    }
</script>

import titleComponent from './title.component.vue';
Vue.component('vue-title', titleComponent);

Then you can use it in your views, e.g.

<vue-title title="Static Title"></vue-title>
<vue-title :title="dynamic.something + ' - Static'"></vue-title>

Title and meta tags can be edited and updated asynchronously.

You can use state management, create a store for SEO using vuex and update each part accordingly.

Or you can update the element by yourself easily

created: function() {  

  ajax().then(function(data){
     document.title = data.title  
     document.head.querySelector('meta[name=description]').content = data.description
  })

}

This answer is for vue 1.x

using requirejs.

define([
  'https://cdn.jsdelivr.net/vue/latest/vue.js'
], function(Vue) {
  var vm = new Vue({
    el: 'html',
    data: {
      hello: 'Hello world'
    }
  });
});

<!DOCTYPE html>
<html id="html">

<head>
  <title>{{ hello }}</title>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.2.0/require.js" data-main="app"></script>
</head>

<body>
  {{ hello }}
  <input v-model="hello" title="hello" />
</body>

</html>

you can do it like this using the ready function to set the initial value and watch to update when the data changes.

<html>
<head>
<title>Replace Me</title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/vue/latest/vue.js"></script>

<div id="app">
  <input v-model="title">
</div>


<script>
new Vue({
    el: '#app',
    ready: function () {
        document.title = this.title
    },
    data: {
        title: 'My Title'
    },
    watch: {
        title: function (val, old) {
            document.title = val
        }
    }
})
</script>

</body>
</html>

also i tried this based on your original code and it works

<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/vue/latest/vue.js"></script>

<div id="app">
  <input v-model="title">
</div>

<script>
new Vue({
    el: 'html',
    data: {
        title: 'My Title'
    }
})
</script>

</body>
</html>
