javascript - 如何互相交换所有div

那就是我的画廊的样子:


我需要javascript / jquery函数:“arrow_left()”和“arrow_right”，用于更改带图片的div的位置(所有div的中间都包含所有div)。例如，当我单击“图像2”上的向右箭头时，“图像2”应与“图像3”交换它们的位置。
下面，我介绍如何将“图像2”与“图像3”交换，而将“图像2”留空(“图像3”将被删除)。

<script>
    function arrow_right(id_number) {
        var present_div = $('#' + id_number);
        id_number = id_number + 1;
        var next_div = $('#' + id_number);

        $(present_div).replaceWith(next_div);
        //$(next_div).replaceWith(present_div); <- doesn't work
    }

    function arrow_left(id_number) {
        var present_div = $('#' + id_number);
        id_number = id_number - 1;
        var prev_div = $('#' + id_number);

        $(present_div).replaceWith(prev_div);
        //$(prev_div).replaceWith(present_div); <- doesn't work
    }
</script>

    <div id='ID_1' class='col-lg-4 col-md-6 portfolio-item'>
    <div class='thumbnail'>
        <div onclick='arrow_left(1);'><span class='glyphicon glyphicon-arrow-left' style='color: yellow; left: 78px; top: 5px;'></span></div>
        <div onclick='arrow_right(1);'><span class='glyphicon glyphicon-arrow-right' style='color: yellow; left: 136px; top: 5px;'></span></div>
        <img id='1' class='img-responsive' src='path/to/img'>
    </div>
</div>
<div id='ID_2' class='col-lg-4 col-md-6 portfolio-item'>
    <div class='thumbnail'>
        <div onclick='arrow_left(2);'><span class='glyphicon glyphicon-arrow-left' style='color: yellow; left: 78px; top: 5px;'></span></div>
        <div onclick='arrow_right(2);'><span class='glyphicon glyphicon-arrow-right' style='color: yellow; left: 136px; top: 5px;'></span></div>
        <img id='2' class='img-responsive' src='path/to/img'>
    </div>
</div>

<div class='clearfix visible-md-block'></div>

<div id='ID_3' class='col-lg-4 col-md-6 portfolio-item'>
    <div class='thumbnail'>
        <div onclick='arrow_left(3);'><span class='glyphicon glyphicon-arrow-left' style='color: yellow; left: 78px; top: 5px;'></span></div>
        <div onclick='arrow_right(3);'><span class='glyphicon glyphicon-arrow-right' style='color: yellow; left: 136px; top: 5px;'></span></div>
        <img id='3' class='img-responsive' src='path/to/img'>

        <img id='6' class='img-responsive' src='path/to/img'>
    </div>
</div>
<div class='clearfix visible-lg-block'></div>

<div class='clearfix visible-md-block'></div>

<div id='ID_7' class='col-lg-4 col-md-6 portfolio-item'>
    <div class='thumbnail'>
        <div onclick='arrow_left(7);'><span class='glyphicon glyphicon-arrow-left' style='color: yellow; left: 78px; top: 5px;'></span></div>
        <div onclick='arrow_right(7);'><span class='glyphicon glyphicon-arrow-right' style='color: yellow; left: 136px; top: 5px;'></span></div>
        <img id='7' class='img-responsive' src='path/to/img'>
    </div>
</div>

我不知道这有多大。如果有人可以帮助我吗？ Mabye有人为此知道其他解决方案，但没有拖放-我测试了jQuery UI可排序，并且效果不佳。

我不需要滑块。我需要在页面中显示所有图像并更改它们的顺序(在管理员面板中)。数据库中的每个图像都有一个“Order”字段，该字段会影响页面上图像的显示顺序。我正在寻找解决方案以便对此订单进行更改。

最佳答案

您可以像这样替换元素externalHTML:

 function arrow_change(el, fw) {
    var id = el.parentElement.parentElement.id;
    var id_number = eval(id.substr(3))
    var present_div = $('#ID_' + id_number + " div").get(0);//get(0) returns first DOM Element
    id_number = id_number + fw //fw is either 1 or -1;
    var next_div = $('#ID_' + id_number + " div").get(0);
    var present_html = present_div.outerHTML;
    var next_html = next_div.outerHTML;
    present_div.outerHTML = next_html;
    next_div.outerHTML = present_html;
}

根据参数的右或左，用el指定参数this，用fw或1指定-1
例如:onclick="arrow_change(this, 1)"用于向右移动。
