How to use JavaScript variables in jQuery selectors?

$(`input[id="${this.name}"]`).hide();

As you're using an ID, this would perform better

$(`#${this.name}`).hide();

---

I highly recommend being more specific with your approach to hiding elements via button clicks. I would opt for using data-attributes instead. For example

<input id="bx" type="text">
<button type="button" data-target="#bx" data-method="hide">Hide some input</button>

Then, in your JavaScript

// using event delegation so no need to wrap it in .ready()
$(document).on('click', 'button[data-target]', function() {
    var $this = $(this),
        target = $($this.data('target')),
        method = $this.data('method') || 'hide';
    target[method]();
});

Now you can completely control which element you're targeting and what happens to it via the HTML. For example, you could use data-target=".some-class" and data-method="fadeOut" to fade-out a collection of elements.

var name = this.name;
$("input[name=" + name + "]").hide();

OR you can do something like this.

var id = this.id;
$('#' + id).hide();

OR you can give some effect also.

$("#" + this.id).slideUp();

If you want to remove the entire element permanently form the page.

$("#" + this.id).remove();

You can also use it in this also.

$("#" + this.id).slideUp('slow', function (){
    $("#" + this.id).remove();
});

$("input").click(function(){
        var name = $(this).attr("name");
        $('input[name="' + name + '"]').hide();    
    });   

Also works with ID:

var id = $(this).attr("id");
$('input[id="' + id + '"]').hide();

when, (sometimes)

$('input#' + id).hide();

does not work, as it should.

You can even do both:

$('input[name="' + name + '"][id="' + id + '"]').hide();
