Jquery ui 使用CSS3转换设置jQueryUI可排序的动画

我如何使用CSS3转换（或任何其他方式）使动作更像iOS中的列表重新排序，其中列表项在拖动时平滑地动画化，因此在拖动时项目会快速移动

[编辑以将其转化为常见问题解答，并为其他想要了解此问题的人节省时间]

演示如何使用平滑动画来设置拖动动画。拖拽时，物品会快速闪开。它使用的效果正是我想要的。很酷

代码如下：

JSFIDDLE:

<style name="impostor_size">
    .marker + li { border-top-width:0px; }
</style>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
    <li>6</li>
</ul>

body { color:white; font-family:Helvetica, sans-serif;  padding: 10px}
ul { float:left; width:300px; overflow:hidden; border-radius:6px; }
li { display:block; position:relative; padding:12px 6px; z-index:1; margin:5px 20px; }
li:after { background:#18629D; display:block; position:absolute; height:100%; width:100%; top:0px; left:0px; content:' '; border-radius:6px; z-index:-1; }
li { -moz-transition:border-top-width 0.1s ease-in; -webkit-transition:border-top-width 0.1s ease-in; border-top:0px solid rgba(0,0,0,0); }
.marker { opacity:0.0; }

var stylesheet = $('style[name=impostor_size]')[0].sheet;
var rule = stylesheet.rules ? stylesheet.rules[0].style : stylesheet.cssRules[0].style;
var setPadding = function(atHeight) {
    rule.cssText = 'border-top-width: '+atHeight+'px'; 
};
$('ul').sortable({
    'placeholder':'marker',
    'start':function(ev, ui) {
        setPadding(ui.item.height());
    },
    'stop':function(ev, ui) {
        var next = ui.item.next();
        next.css({'-moz-transition':'none', '-webkit-transition':'none', 'transition':'none'});
        setTimeout(next.css.bind(next, {'-moz-transition':'border-top-width 0.1s ease-in', '-webkit-transition':'border-top-width 0.1s ease-in', 'transition':'border-top-width 0.1s ease-in'}));
    }
});

HTML:

<style name="impostor_size">
    .marker + li { border-top-width:0px; }
</style>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
    <li>6</li>
</ul>

body { color:white; font-family:Helvetica, sans-serif;  padding: 10px}
ul { float:left; width:300px; overflow:hidden; border-radius:6px; }
li { display:block; position:relative; padding:12px 6px; z-index:1; margin:5px 20px; }
li:after { background:#18629D; display:block; position:absolute; height:100%; width:100%; top:0px; left:0px; content:' '; border-radius:6px; z-index:-1; }
li { -moz-transition:border-top-width 0.1s ease-in; -webkit-transition:border-top-width 0.1s ease-in; border-top:0px solid rgba(0,0,0,0); }
.marker { opacity:0.0; }

var stylesheet = $('style[name=impostor_size]')[0].sheet;
var rule = stylesheet.rules ? stylesheet.rules[0].style : stylesheet.cssRules[0].style;
var setPadding = function(atHeight) {
    rule.cssText = 'border-top-width: '+atHeight+'px'; 
};
$('ul').sortable({
    'placeholder':'marker',
    'start':function(ev, ui) {
        setPadding(ui.item.height());
    },
    'stop':function(ev, ui) {
        var next = ui.item.next();
        next.css({'-moz-transition':'none', '-webkit-transition':'none', 'transition':'none'});
        setTimeout(next.css.bind(next, {'-moz-transition':'border-top-width 0.1s ease-in', '-webkit-transition':'border-top-width 0.1s ease-in', 'transition':'border-top-width 0.1s ease-in'}));
    }
});

脚本：

<style name="impostor_size">
    .marker + li { border-top-width:0px; }
</style>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
    <li>6</li>
</ul>

body { color:white; font-family:Helvetica, sans-serif;  padding: 10px}
ul { float:left; width:300px; overflow:hidden; border-radius:6px; }
li { display:block; position:relative; padding:12px 6px; z-index:1; margin:5px 20px; }
li:after { background:#18629D; display:block; position:absolute; height:100%; width:100%; top:0px; left:0px; content:' '; border-radius:6px; z-index:-1; }
li { -moz-transition:border-top-width 0.1s ease-in; -webkit-transition:border-top-width 0.1s ease-in; border-top:0px solid rgba(0,0,0,0); }
.marker { opacity:0.0; }

var stylesheet = $('style[name=impostor_size]')[0].sheet;
var rule = stylesheet.rules ? stylesheet.rules[0].style : stylesheet.cssRules[0].style;
var setPadding = function(atHeight) {
    rule.cssText = 'border-top-width: '+atHeight+'px'; 
};
$('ul').sortable({
    'placeholder':'marker',
    'start':function(ev, ui) {
        setPadding(ui.item.height());
    },
    'stop':function(ev, ui) {
        var next = ui.item.next();
        next.css({'-moz-transition':'none', '-webkit-transition':'none', 'transition':'none'});
        setTimeout(next.css.bind(next, {'-moz-transition':'border-top-width 0.1s ease-in', '-webkit-transition':'border-top-width 0.1s ease-in', 'transition':'border-top-width 0.1s ease-in'}));
    }
});

通过利用可排序api中的“change”函数，我改进了上述所有功能。这是代码。查看下面的提琴以查看所需的css

$('ul').sortable({
placeholder:'marker',
distance: 15,
cursor: 'move',
revert: 200,
start:function(ev, ui) {
   $(".marker").css({"height": "0px"});
    console.log("start");
},
change:function(ev, ui) {
    $(".marker").css({"height": "0px"});
    setTimeout(function(){
        $(".marker").css({"height": "40px"});
    },10);
} });

您可以看到完整的代码示例

这里是另一个例子，通过CSS 3转换为列表设置动画可能重复li的需要：在这里之后？这非常有效！但真遗憾，它必须如此刻薄。
