JS实现一览画面中动态弹出悬浮窗口的实例

JSP页面弹出层结构

<!-- 物流详情弹出页面 start --> 
<s:iterator value="lrVo" var="lrVo" id="lrVo" status="st"> 
<div class="logisticscenter_xq" style="display: none;" id='<s:property value="#lrVo.logisticNO"/>'> 
<dl> 
<dt><strong><s:text name="struts.webui.logistics.label.logisticsDetails"/>：</strong></dt> 
<dd><strong class="close_wind">X</strong></dd> 
</dl> 
<div class="information logistics_win"> 
<table width="" border="0" cellspacing="0" cellpadding="0"> 
<tr> 
<td class="r_text"><span class="icon9">*</span><s:text name="struts.webui.logistics.label.logisticsNumber"/>：</td> 
<td></td> 
<td colspan="3" id="logisticNo"><s:property value="#lrVo.logisticNO"/></td> 
</tr> 
<tr> 
<td valign="top" class="r_text"><span class="icon9">*</span><s:text name="struts.webui.logistics.label.distribution"/>：</td> 
<td></td> 
<td colspan="3" style="text-align:left" id="content"><s:property value="#lrVo.content" escape="false"/></td> 
</tr> 
</table> 
</div> 
</div> 
</s:iterator> 
<!--物流详情弹出窗口 end--> 

弹出层CSS样式定义

.logisticscenter_xq{ 
position: absolute; 
width:710px; 
border:solid 2px #787878; 
background: #edfcfe; 
z-index: 2; 
} 

JS动态定位逻辑

// 计算对象居中需要设置的left和top值 
// 参数： 
// _w - 对象的宽度 
// _h - 对象的高度 
function getLT(_w,_h) 
{ 
var de = document.documentElement; 
// 获取当前浏览器窗口的宽度和高度 
// 兼容写法，可兼容ie,ff 
var w = self.innerWidth || (de&&de.clientWidth) || document.body.clientWidth; 
var h = (de&&de.clientHeight) || document.body.clientHeight; 
// 获取当前滚动条的位置 
// 兼容写法，可兼容ie,ff 
var st= (de&&de.scrollTop) || document.body.scrollTop; 
var topp=0; 
if(h>_h) 
topp=(st+(h - _h)/2); 
else 
topp=st; 
var leftp = 0; 
if(w>_w) 
leftp = ((w - _w)/2); 
// 左侧距，顶部距 
return [leftp,topp]; 
} 
//获取鼠标位置GetPostion 
function GetPostion(e) { 
var x = getX(e); 
var y = getY(e); 
} 
function getX(e) { 
e = e || window.event; 
return e.pageX || e.clientX + document.body.scrollLeft - document.body.clientLeft 
} 
function getY(e) { 
e = e|| window.event; 
return e.pageY || e.clientY + document.body.scrollTop - document.body.clientTop 
} 
//判断浏览器类型 
function getOs() 
{ 
var OsObject = ""; 
if(navigator.userAgent.indexOf("MSIE")>0) { 
return "MSIE"; 
} 
if(isFirefox=navigator.userAgent.indexOf("Firefox")>0){ 
return "Firefox"; 
} 
if(isSafari=navigator.userAgent.indexOf("Safari")>0) { 
return "Safari"; 
} 
if(isCamino=navigator.userAgent.indexOf("Camino")>0){ 
return "Camino"; 
} 
if(isMozilla=navigator.userAgent.indexOf("Gecko/")>0){ 
return "Gecko"; 
} 
} 

<script language="javascript" type="text/javascript" src="<s:url value="/js/aligncenter.js"/>"></script> 

<a class="view_button" onclick="viewLogistics(event,'<s:property value="#lrVo.logisticNO"/>')" href="####"><s:text name="struts.webui.logistics.label.view"/></a> 

列表页调用方法实现

function viewLogistics(event,logisticNO){ 
var os = getOs(); 
var y = getY(event); 
if(os=='MSIE'){ 
y=window.event.y+405; 
} 
$(".logisticscenter_xq").hide(); 
$("#"+logisticNO).show(); 
$("#"+logisticNO).css("top",y+15); 
}
