ASP.NET页面中预览图片和flash附加关闭功能

由于本项目运用了母版页技术，所以document.getElementById()括号中的元素id号有变化，具体参考http://blog.youkuaiyun.com/sytWeibo/archive/2009/07/10/4338880.aspx

function LoadImgDiv() { var imgDiv = document.getElementById("ctl00_ContentPlaceHolder1_divImage"); imgDiv.innerHTML = '<img src="' + document.getElementById(" mce_src="' + document.getElementById("ctl00_ContentPlaceHolder1_txtFileName").value + '" />' + '<input type="button" value="关闭" onclick="HideImgDiv()" />'; imgDiv.style.display="block"; } function HideImgDiv() { var imgDiv = document.getElementById("ctl00_ContentPlaceHolder1_divImage"); imgDiv.style.display="none"; } function LoadFlashDiv() { var flashDiv = document.getElementById("ctl00_ContentPlaceHolder1_divFlash"); flashDiv.innerHTML = '<object id="objclose" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" height="160" width="584" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">' + '<param name="Movie" value=">' + document.getElementById("ctl00_ContentPlaceHolder1_txtFileName").value + '">' + '<param name="Src" value="' + document.getElementById("ctl00_ContentPlaceHolder1_txtFileName").value + '">' + '<embed src="' + document.getElementById(" mce_src="' + document.getElementById("ctl00_ContentPlaceHolder1_txtFileName").value + '"' + 'quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" ' + ' type="application/x-shockwave-flash" width="584" height="160">' + '</embed>' + '</object>' + '<input type="button" value="关闭" onclick="HideFlashDiv()" />'; flashDiv.style.display="block"; } function HideFlashDiv() { var objclose=document.getElementById("objclose"); var flashDiv = document.getElementById("ctl00_ContentPlaceHolder1_divFlash"); flashDiv.style.display="none"; objclose.outerHTML=""; }  

对应的HTML代码:

<%--该div用于弹出预览图片--%> <div id="divImage" style="position: absolute; display: none;" mce_style="position: absolute; display: none;" runat="server"> </div> <%--该div用于弹出预览Flash--%> <div id="divFlash" style="position: absolute; display: none;" mce_style="position: absolute; display: none;" runat="server">
