jquery 插件化##
起始插件化：
; (function($, window, undefined) {
$.fn.drag = function(options) {
drag(this)
}
})(jquery, window, undefined);
其他的代碼類(lèi)似前篇拖拽基礎(chǔ)篇http://www.itdecent.cn/p/feca77ec252e。只是需要將一些dom操作改為jquery操作。詳細(xì)代碼：
; (function($, window, undefined) {
//拖拽元素
function DragElement(node) {
this.target = node;
node.onselectstart = function() {
return false;//防止文字選中
}
}
DragElement.prototype = {
constructor: DragElement,
setXY: function(x, y) {
this.x = parseInt(x) || 0;
this.y = parseInt(y) || 0;
return this;
},
setTargetCss: function(css) {
$(this.target).css(css);
return this;
}
}
//鼠標(biāo)
function Mouse() {
this.x = 0;
this.y = 0;
}
Mouse.prototype.setXY = function(x, y) {
this.x = parseInt(x);
this.y = parseInt(y);
}
//拖拽配置
var draggableConfig = {
zIndex:10,
dragElement: null,
mouse: new Mouse()
};
var draggableStyle = {
dragging: {
cursor: 'move'
},
defaults: {
cursor: 'auto'
}
}
var $document = $(document);
function drag($ele) {
var $dragNode = $ele;
$dragNode.on({
'mousedown': function(event) {
var dragElement = draggableConfig.dragElement = new DragElement($ele.get(0));
draggableConfig.mouse.setXY(event.clientX, event.clientY);
draggableConfig.dragElement.setXY(dragElement.target.style.left, dragElement.target.style.top)
.setTargetCss({
'zIndex': draggableConfig.zIndex ++,
'position': 'relative'
});
},
'mouseover': function() {
$(this).css(draggableStyle.dragging);
},
'mouseout':function() {
$(this).css(draggableStyle.defaults);
}
})
}
function move(event) {
if(draggableConfig.dragElement) {
var mouse = draggableConfig.mouse,
dragElement = draggableConfig.dragElement;
dragElement.setTargetCss({
'left': parseInt(event.clientX - mouse.x + dragElement.x) + 'px',
'top': parseInt(event.clientY - mouse.y + dragElement.y) + 'px'
});
$document.off('mousemove', move);
setTimeout(function() {
$document.on('mousemove', move);
}, 25);
}
}
$document.on({
"mousemove": move,
'mouseup': function() {
draggableConfig.dragElement = null;
}
});
$.fn.drag = function(options) {
drag(this)
}
})(jQuery, window, undefined);
拖拽引用：
window.onload = function() {
var dragObj = $("#drag");
dragObj.drag();
}
jQuery拖拽插件 —— sortable##
sortable.js###
sortable.js:是一個(gè)獨(dú)立的JS插件，不需要jquery，Sortable非常輕量，壓縮后只有2KB，采用的是html5拖拽。https://github.com/RubaXa/Sortable
有關(guān)html5拖拽請(qǐng)期待 拖拽三 O(∩_∩)O哈哈~。
簡(jiǎn)單例子：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="NARUTOne">
<title>Sortable拖拽</title>
<script type="text/javascript" src="./lib/Sortable.js"></script>
<style media="screen">
div {
width: 800px;
padding: 50px;
border: 1px solid #ededed;
margin: 100px auto;
}
div::after {
content: '';
display: table;
clear: both;
}
p {
width: 420px;
}
span {
width: 120px;
margin-right: 20px;
margin-bottom: 10px;
float: left;
height:30px;
/*border: 1px solid red;*/
background-color: #26a4fe;
color: #fff;
font-weight: bold;
text-align: center;
line-height: 30px;
}
</style>
</head>
<body>
<div class="">
<p id="sortleft" class='item'>
<span>1</span>
<span>2</span>
<span>3</span>
<span>4</span>
<span>5</span>
<span>6</span>
<span>7</span>
</p>
</div>
</body>
<script type="text/javascript">
var el = document.getElementById('sortleft');
new Sortable(el,{
group: "name"
});
</script>
</html>
當(dāng)然還有許多方法和配置，這就需要大神們自己看看文檔了O(∩_∩)O哈哈,小渣我就不說(shuō)了。/(ㄒoㄒ)/~
jQueryUI——sortable###
sortable.js也可以轉(zhuǎn)換為jquery模式，需要引入一些文件，這里就不說(shuō)了?，F(xiàn)在說(shuō)說(shuō)jqueryUI這款插件，里面也是有類(lèi)似sortable的拖拽插件的。

當(dāng)然，在jqueryUI插件中還有許多有趣強(qiáng)大的功能，有興趣的猿（媛）們可以看看。
這篇文章是在比較忙里偷閑下寫(xiě)的，可能比較賴(lài)，沒(méi)時(shí)間具體分析了，就直接上代碼了。起始本人也是比較討厭直接看代碼的，這樣就沒(méi)有那種分享的意味了。哎，各位就先將就下吧，有問(wèn)題，有bug可以評(píng)論下留言哈。(__) 嘻嘻……。
接下來(lái)拖拽篇還有一篇HTML5下的拖拽，這篇我會(huì)好好的寫(xiě)的，好好分享下學(xué)習(xí)心得，好期待哈O(∩_∩)O哈！
