检测输入中键入的单词和字母，并对具有相同字母的其他元素（div中的文本）进行排序

Question

I want to make an input, in which you type words or letters to sort some kind of elements. For example: there are divs with different words in them, and when you type something in the input immediately sort the divs which have the same letters as in the input...

<input type="text" placeholder="Sort by...">

<div class="sortable-items">
    <div>dogs</div>
    <div>cats</div>
    <div>dogs</div>
    <div>dogs</div>
    <div>cats</div>
    <div>cats</div>
    <div>dogs</div>
</div>

If you listen for the keyup event on the input, the function will call every time you type or remove a letter. You can then check if the input matches any of the divs' value, and hide/show it based on that.

$('#search').keyup(function(){
    var searchTerm = $(this).val();
    $(".sortable-items div").each(function(){
        if($(this).text().match(searchTerm)){
            $(this).show();
        }else{
            $(this).hide();
        }
    });
});
