    Automatically focus on an input field upon page load in Ember

    // myView.handlebars
    {{ input autofocus="true" }}
    {{ autofocus }}
    {# end of file #}


    Setting the keyboard focus on a specific input element is a quite standard UI behaviour but rather tedious to accomplish in Ember.

    Gladly, there’s this very useful recipe on the Ember web site on how you’re supposed to do that; basically, you set the focus after the didInsertElement Ember event fires - done! This, this and this Stackoverflow answer propose similar techniques.

    Unfortunately, the proposed solutions require subclassing into your own Views, which I do not like so much for various reasons.

    Thus, Change!


    ember-autofocus bundles Ember's proposed technique into a neat package and adds a few improvements along the way:

    • Just add water. No coding. Load it, boom, hooray!
    • No more subclassing. Because, subclassing.
    • Works on any element. If you pass it a CSS selector.
    • No configuration. If you don't pass a CSS selector it takes the first text input it finds.
    • HTML5 compatible. Uses the native autofocus attribute if available.
    • HTML<5 fallback. No HTML5, no problem.
    • Tiny. 0.000000670552254 Gigabytes.
    • It’s really elegant. Elegance is a glowing inner peace.

    How it works

    • Installs an autofocus attribute for InputField for HTML5 compatibility
    • Adds an {{autofocus}} View that uses jQuery to set the focus
    • learn from the source, it’s really minimal



    bower install ember-autofocus

    In your index.html:

    <script type="text/javascript" src="bower_components/ember-autofocus/dist/ember-autofocus.min.js)"></script>


    Most compatible (recommended)

    • Sets the focus on the first <input|button|textarea> element with an autofocus attribute.
    • Uses the browser’s native HTML5 functionality if available.
    • Works in pre-HTML5 browsers.
    // myView.handlebars
    {{ input autofocus="autofocus"}}
    {{ autofocus }}
    {# end of file #}


    Autofocus on the first <input> element.

    // myView.handlebars
    {{ input }}
    {{ autofocus }}
    {# end of file #}

    Most Sophisticated

    Use a CSS selector to autofocus on a specific element.

    // myView.handlebars
    {{ autofocus on='#my-special-element .my-unique-class' }}
    {# end of file #}

    Automatic scrolling in HTML5

    Safari, Chrome, Firefox and possibly other HTML5 browsers that support autofocus natively will set the keyboard focus to the specified field and will automatically scroll there. In my use case, that's not wanted because the input field may be below the screen fold and automatically scrolling there is not what users would expect.

    You can choose whether or not you want the scrolling behavior with the scrolling option:

    scrolling = "true|false"

    The default is false, which means that the browser will not scroll to the autofocus element.

    // myView.handlebars
    {{ autofocus scrolling="true" }}
    {# end of file #}


    • Will focus even on hidden/invisible items. Pull Requests welcome.


    I have found some very valuable advice during my research which I have built into ember-autofocus:
