javascript - jQuery 虚拟键盘正在保存先前输入的值

Question

我使用虚拟键盘，但遇到了问题。

问题是，在一个用户界面中，我有几个输入字段，对于每个字段，我都有类“输入”，它调用键盘。

当我点击第一个输入并输入数据时，先前输入字段的数据将复制到新的。

$(document).ready(function () {
    $(".numpad").hide();
    $('.input').click(function () {
        $('.numpad').fadeToggle('fast');
    });

    $('.del').click(function () {
        $('.input').val($('.input').val().substring(0, $('.input').val().length - 1));
    });
    $('.faq').click(function () {
        alert("It's virtual keyboard");
    })
    $('.shuffle').click(function () {
        $('.input').val($('.input').val() + $(this).text());
    });

});

$(".input").on("click", function () {
    $('.modal, .cover').removeClass("hidden");
    $('.modal').addClass("zoom");
});

//hide modal
$(".cover, .close").on("click", function () {
    $('.modal').attr('class', 'modal');
    $('.modal, .cover').addClass("hidden");
});

.keyBoardButton {
    margin: 13px;
}

.keyBoardButton {
    display: inline-block;
    border: 1px solid #fff;
    color: #fff;
    border-radius: 30px;
    -webkit-border-radius: 30px;

    height: auto;
    font-size: 22px;
    padding: 20px 27px;

}

    .keyBoardButton:hover, .keyBoardButton:active {
        border: 1px solid #FFFFFF;
        color: #000;
        background-color: #fff;
    }

.cover {
    z-index: 1;
    position: fixed;

    width: 100%;
    background-color: #333;

    .modal .content p {

        color: #fff;
        height: 50px;
        width: 100%;
        position: absolute;
        top: 0;
        bottom: 0;
        left: 0;
        right: 0;
        margin: auto;
    }

.tiltup {
    display: block;
    transform: perspective(300px);
    animation: tiltup 0.7s;

    30% {

    100% {

}

.zoom {
    display: block;
    animation: zoom 0.7s;

}

@keyframes zoom {
    0% {
        opacity: 0;
        transform: scale(0, 0);
    }

    30% {
        opacity: 0;
    }

    100% {
        bottom: 0;
    }
}

.hidden {

正如您所看到的，当点击输入字段时，虚拟键盘将在模式窗口中打开，添加数据后，在其他输入字段中该数据将复制。

因此，对于每个输入，我需要单独的数据。

看看这个片段，你就会得到一些想法。

$(document).ready(function () {

 var selected_inp;
    $(".numpad").hide();
    $('.input').click(function () {
       selected_inp = $(this);
        $('.numpad').fadeToggle('fast');
    });

    $('.del').click(function () {
        $('.input').val($('.input').val().substring(0, $('.input').val().length - 1));
    });
    $('.faq').click(function () {
        alert("It's virtual keyboard");
    })
    $('.shuffle').click(function () {
        //$('.input').val($('.input').val() + $(this).text());
        selected_inp.val($(this).text());
    });
    (function ($) {

        $.fn.shuffle = function () {

            var allElems = this.get(),
                getRandom = function (max) {
                    return Math.floor(Math.random() * max);
                },
                shuffled = $.map(allElems, function () {
                    var random = getRandom(allElems.length),
                        randEl = $(allElems[random]).clone(true)[0];
                    allElems.splice(random, 1);
                    return randEl;
                });

            this.each(function (i) {
                $(this).replaceWith($(shuffled[i]));
            });

            return $(shuffled);

        };

    })(jQuery);

});

$(".input").on("click", function () {
