移动div块

Question

我需要制作类似滑块的东西。但我有jQuery的问题我不知道如何正确的力量移动我的项目。也许我没有正确的css文件，也许这需要改变？请帮助。

我有html：

<div class="carusel-section">
    <div class="top-indent">
        <div class="carusel-container">
            <div class="arrow-back">
                <img src="img/arrow-back.png" alt="back">
            </div>
            <div class="item item-first"><h4 class="item-text">200x120</h4></div>
            <div class="item"><h4 class="item-text">200x120</h4></div>
            <div class="item"><h4 class="item-text">200x120</h4></div>
            <div class="item"><h4 class="item-text">200x120</h4></div>
            <div class="item"><h4 class="item-text">200x120</h4></div>
            <div class="item"><h4 class="item-text">200x120</h4></div>
            <div class="arrow-forward">
                <img src="img/arrow-forward.png" alt="forward">
            </div>
        </div>
    </div>
</div>

的CSS：

.carusel-container {
    max-width: 742px;
    margin-left: 5px;
}

    .carusel-container:before {
        width: 40px;
        left: 17px;
    }

    .carusel-container .arrow-back {
        top: 43px;
        left: 28px;
    }

    .carusel-container .item-first {
        margin: 0 0 0 57px;
    }

    .carusel-container .arrow-forward {
        top: 43px;
        right: 12px;
    }

jQuery的：

$(".arrow-back").click(function () {
    console.log("BACKKK");
    $(".item").css("margin-left", "-50px");
});

$(".arrow-forward").click(function () {
    console.log("TOWARDDD");
    $(".item").css("margin-right", "-50px");
});

最初，一个元素应该只显示，所有其他元素都应该隐藏

按下下一个按钮，除下一个元素外，所有元素都应该消失，后退按钮也是如此

我建议你使用这个简单的代码：

HTML代码：

<div id="carousel-container">
        <a href="#" class="control_next">>></a>
        <ul>
            <li>200x120</li>
            <li>200x120</li>
            <li>200x120</li>
            <li>200x120</li>
            <li>200x120</li>
            <li>200x120</li>
        </ul>
        <a href="#" class="control_prev"><<</a>
</div>

CSS代码：

#carousel-container {
    position: relative;
    overflow: hidden;
    margin: 20px auto 0 auto;
    border-radius: 4px;
}
#carousel-container ul {
    position: relative;
    margin: 0;
    padding: 0;
    height: 200px;
    list-style: none;
}
#carousel-container ul li {
    position: relative;
    display: block;
    float: left;
    margin: 0;
    padding: 0;
    width: 500px;
    height: 300px;
    background: #ccc;
    text-align: center;
    line-height: 300px;
}
a.control_prev,
a.control_next {
    position: absolute;
    top: 40%;
    z-index: 999;
    display: block;
    padding: 4% 3%;
    width: auto;
    height: auto;
    background: #2a2a2a;
    color: #fff;
    text-decoration: none;
    font-weight: 600;
    font-size: 18px;
    opacity: 0.8;
    cursor: pointer;
}
a.control_prev:hover,
a.control_next:hover {
    opacity: 1;
    -webkit-transition: all 0.2s ease;
}
a.control_prev {
    border-radius: 0 2px 2px 0;
}
a.control_next {
    right: 0;
    border-radius: 2px 0 0 2px;
}

JS代码：

jQuery(document).ready(function ($) {

    var slideCount = $('#carousel-container ul li').length;
    var slideWidth = $('#carousel-container ul li').width();
    var slideHeight = $('#carousel-container ul li').height();
    var sliderUlWidth = slideCount * slideWidth;

    $('#carousel-container').css({ width: slideWidth, height: slideHeight });

    $('#carousel-container ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });

    $('#carousel-container ul li:last-child').prependTo('#carousel-container ul');

    function moveLeft() {
        $('#carousel-container ul').animate({
            left: + slideWidth
        }, 200, function () {
            $('#carousel-container ul li:last-child').prependTo('#carousel-container ul');
            $('#carousel-container ul').css('left', '');
        });
    };

    function moveRight() {
        $('#carousel-container ul').animate({
            left: - slideWidth
        }, 200, function () {
            $('#carousel-container ul li:first-child').appendTo('#carousel-container ul');
            $('#carousel-container ul').css('left', '');
        });
    };

    $('a.control_prev').click(function () {
        moveLeft();
    });

    $('a.control_next').click(function () {
        moveRight();
    });

});
