斯人..而已..
刚出炉的 大家需要的拿去用吧
var DragAndDrop = function() { var _clientWidth; var _clientHeight; var _controlObj; var _dragObj; var _flag = false; var _dragObjCurrentLocation; var _mouseLastLocation; var getElementDocument = function(element) { //返回某元素的根元素 return element.ownerDocument || element.document }; var dragMouseDownHandler = function(evt) { if (_dragObj) { evt = evt || window.event; //获取浏览器宽 _clientWidth = document.body.clientWidth; //获取浏览器高 _clientHeight = document.documentElement.scrollHeight; _flag = true; //定义结构体 保存当前left和TOP的值 _dragObjCurrentLocation = { x: $(_dragObj).offset().left, y: $(_dragObj).offset().top }; //定义结构体 保存点击鼠标时的位置坐标 _mouseLastLocation = { x: evt.screenX, y: evt.screenY }; //绑定事件 $(document).bind("mousemove", dragMouseMoveHandler); $(document).bind("mouseup", dragMouseUpHandler); //组织默认动作 if (evt.preventDefault) { evt.preventDefault() } else { evt.returnValue = false } } }; var dragMouseMoveHandler = function(evt) { if (_flag) { evt = evt || window.event; var _mouseCurrentLocation = { x: evt.screenX, y: evt.screenY }; _dragObjCurrentLocation.x = _dragObjCurrentLocation.x + (_mouseCurrentLocation.x - _mouseLastLocation.x); _dragObjCurrentLocation.y = _dragObjCurrentLocation.y + (_mouseCurrentLocation.y - _mouseLastLocation.y); _mouseLastLocation = _mouseCurrentLocation; $(_dragObj).css("left", _dragObjCurrentLocation.x + "px"); $(_dragObj).css("top", _dragObjCurrentLocation.y + "px"); //组织默认动作 if (evt.preventDefault) { evt.preventDefault() } else { evt.returnValue = false } } }; var dragMouseUpHandler = function(evt) { if (_flag) { evt = evt || window.event; cleanMouseHandlers(); _flag = false } }; var cleanMouseHandlers = function() { if (_controlObj) { $(_controlObj.document).unbind("mousemove"); $(_controlObj.document).unbind("mouseup") } }; return { //注册事件 Register: function(dragObj, controlObj) { _dragObj = dragObj; _controlObj = controlObj; $(_controlObj).bind("mousedown", dragMouseDownHandler) } } } ();
使用方法
<mce:style><!-- .div{width:200px; height:150px; border:1px solid #ccc; margin:10px;position:absolute} .cursor{cursor:move} --></mce:style><style mce_bogus="1">.div{width:200px; height:150px; border:1px solid #ccc; margin:10px;position:absolute} .cursor{cursor:move}</style> <body> <div class="div" id="msg1"> <div class="cursor" id="title">DIV层二</div> <div id="biger" style="top: 130px; position:absolute; border:1px solid #e7e7e7; width:100%; cursor:nw-resize">123</div> </div> <mce:script type="text/javascript"><!-- var title=document.getElementById('title'); var msg1=document.getElementById('msg1'); DragAndDrop.Register(msg1,biger) // --></mce:script> </body>
