Improved autofocus with pre-existent text.

{% include "footer.html" %}

<script>

$(document).ready(function() {

    var search_text_input = $("#search_text");

    var len = search_text_input.val().length;

    search_text_input[0].focus();

    search_text_input[0].setSelectionRange(len, len);

});

</script>
