我有一个使用 jQuery UI 可排序的图像查看器/放大器。当有很多图像时,窗口变为可滚动以容纳它们。在这种情况下,将图像从一个地方拖到另一个地方时会出现抖动。出现的滚动条也会跳动。

我曾在除 IE 之外的所有领域工作过的原始 CSS。然后我生成了一些新的 CSS,它现在可以在所有浏览器中使用,但是我必须保持查看器的区域相对较小,如果有很多图像(即有些完全隐藏并且拖动变得困难),这并不理想。它似乎只发生在观看者的实际区域超出窗口边界时。我对通过 CSS 或 jQuery 的解决方案持开放态度。首先尝试了 CSS b/c,这就是我所知道的。谢谢!

首先,这里是 jQuery:

    $(document).ready(function($){
var deviceAgent = navigator.userAgent.toLowerCase();
var agentID = deviceAgent.match(/(iphone|ipod|ipad)/);
if (agentID) {

    $("#gallery, #viewer").sortable({
        connectWith: ".images",
        items: "div",
        forcePlaceholderSize: true,
        forceHelperSize: true,
        receive: function (event, ui) {
            switch (ui.item.parent().attr("id")) {
                case "viewer":
                    ui.item.animate({ height: "250px", width: "250px" });
                    break;
                case "gallery":
                    ui.item.animate({ height: "96px", width: "96px" });
                    break;
            }
        }

    }).disableSelection();

}

else {
    $("#gallery, #viewer").sortable({
        connectWith: ".images",
        items: "div",
        forcePlaceholderSize: true,
        forceHelperSize: true,
        receive: function (event, ui) {
            switch (ui.item.parent().attr("id")) {
                case "viewer":
                    ui.item.css({ height: "525px", width: "auto" });
                    break;
                case "gallery":
                    ui.item.css({ height: "150px", width: "auto" });
                    break;
            }
        }

    }).disableSelection();
}

});

除了 IE 之外的所有内容都不会跳转的 CSS:

        html, body {min-height:100%;}
    .hangingIndent{ padding-left:22px; text-indent:-22px;}
    #gallery {width: 95%; min-height: 100px; overflow:auto; *overflow:inherit; margin-bottom: 10px;}
    *html #gallery {height: 100px; }
    #gallery .image {float: left; width: auto; height: 150px; padding: 0; margin-right: 10px; text-align: center; background-color:#e2e2e2;}
    #gallery .image img { width: auto; height: 148px; border: solid 1px black; cursor: move; }
    #viewer {width: 95%; min-height: 250px; background-color:#A3A3A3; padding: 1%; overflow:auto; *overflow:inherit;}
    * html #viewer {height: 250px;}
    #viewer .image {float: left; height: 325px; width: auto; padding: 0; margin-right: 10px; text-align: center; background-color:#e2e2e2;}
    #viewer .image img {width: auto; height: 525px; border: solid 3px white; cursor: move; }
    #viewer h4 {line-height: 1em; margin: 0 0 0.4em; color:#000;}  

和所有可以工作的 CSS,但放大的图像在可滚动区域内:

        html, body {min-height:100%;}
    .hangingIndent{ padding-left:22px; text-indent:-22px;}
    #gallery
    {
        width: 95%;
        min-height: 100px;
        height: 100px;
        overflow: auto;
        margin-bottom: 10px;
    }
    #gallery {}
    #gallery .image {float: left; width: auto; height: 150px; padding: 0; margin-right: 10px; text-align: center; background-color:#e2e2e2;}
    #gallery .image img { width: auto; height: 148px; border: solid 1px black; cursor: move; }
    #viewer
    {
        width: 95%;
        height: 250px;
        min-height: 250px;
        background-color: #A3A3A3;
        padding: 1%;
        overflow: auto;
    }
        #viewer .image
        {
            float: left;
            height: 325px;
            width: auto;
            padding: 0;
            margin-right: 10px;
            text-align: center;
            background-color: #e2e2e2;
                border:none;
        }
            #viewer .image img
            {
                width: auto;
                height: 525px;
                border: solid 3px white;
                cursor: move;
            }
    #viewer h4 {line-height: 1em; margin: 0 0 0.4em; color:#000;}

和 HTML:

    <div id="gallery" class="images">
<div class="ui-corner-tr image"><img src="../../../../../images/Fig267b.jpg" alt="" title="" /></div>
<div class="ui-corner-tr image"><img src="../../../../../images/Question_9a.jpg" alt="" title="" /></div>
<div class="ui-corner-tr image"><img src="../../../../../images/Question_9b.jpg" alt="" title="" /></div>
<div class="ui-corner-tr image"><img src="../../../../../images/Question_9c.jpg" alt="" title="" /></div>
<div class="ui-corner-tr image"><img src="../../../../../images/xray1.JPG" alt="" title="" /></div>
<div class="ui-corner-tr image"><img src="../../../../../images/xray2.JPG" alt="" title="" /></div>
</div>
<div id="viewer" class="images">
<h4>Drag the images to the area above to remove them from the viewing tool.</h4>
</div>

尝试添加溢出:隐藏;到父元素。我不确定这在这种情况下是否有效,但它通常会消除“闪烁”效果。
