web中,如何读取客户端Word内容并且显示在页面中?
我发现有2种方法,一种是直接在客户端操作,一种是把客户端的word上传到服务器端操作,这2种各有优缺点。
我现就举出客户端操作的例子
首先在.aspx中添加如下js代码
<script language='javascript'>
//默认word转化文件放于C:\\下 var os__localPath = "C:\\"; //保存的文件名 var os__localFile = "defaultFileWord.htm"; var os__xmlDom = new ActiveXObject("MSXML2.DOMDocument"); var os__xmlFSO ;
//保存数据到当前客户端(可以传入一个要保存的文件名). function os_SaveToLocal() { var _saveAs = ""; if(arguments.length > 0) _saveAs = arguments[0] + ""; else _saveAs = os__localFile; try { if(os__xmlFSO == null) os__xmlFSO = new ActiveXObject("Scripting.FileSystemObject"); } catch(e){window.alert(e);} } //Word转化为Html文件 function WorcChangeHtml() { var os_xmlFSO; //获得上传控件对象 var objUpFile = window.document.Form1.updFile; //获得客户端Word文件路径和文件 var UpFileValue = window.document.Form1.updFile.value; if(os__xmlFSO == null) os__xmlFSO = new ActiveXObject("Scripting.FileSystemObject"); try { if(window.document.Form1.updFile.value == "") { alert('请选择对应的Word文件'); objUpFile.focus(); } else if(UpFileValue.indexOf(".doc") == -1) { alert('您选择的不是Word文件 \r\n请选择正确的Word文件'); objUpFile.focus(); } else if(!os__xmlFSO.FileExists(objUpFile.value)) { alert('对应的Word文件不存在'); objUpFile.focus(); } else { var wdFormatHTML = 8; var objWord = new ActiveXObject("Word.Application"); objWord.Application.Visible = false; var objDoc = objWord.Documents.Open(UpFileValue); objDoc.SaveAs(os__localPath+os__localFile, wdFormatHTML); window.document.Form1.updFile.value = ""; objDoc.Close(); objWord.Quit(); var GetHtml = GetLine(); var iBeginIndex = GetHtml.indexOf("<body"); var iEndIndex = GetHtml.lastIndexOf("</body>");
GetHtml = GetHtml.substring(iBeginIndex,iEndIndex+7).replace("<body","<div"); GetHtml = GetHtml.replace("</body>","</div>"); //将转化后的值赋给页面控件txtIdea的值,我为了将Word值保存进数据库所以用<input type = "hidden" ..... 如果将Word内容显示可以考虑 window.document.Form1."你的显示控件ID".innerText = GetHtml; window.document.Form1.txtIdea.value = GetHtml; } } catch(e){window.alert(e);} } //读取文本文件 function GetLine() { var fso, txtfile, strValue; var ForReading = 1, ForWriting = 2; fso = new ActiveXObject("Scripting.FileSystemObject"); txtfile = fso.OpenTextFile(os__localPath+os__localFile, ForReading); while(!txtfile.AtEndOfStream) { strValue = strValue + txtfile.ReadLine(); } txtfile.Close(); return(strValue); }
</script>
注意页面上需要添加以下2个控件和对应的客户端事件
<input id="updFile" type="file" style="BORDER-RIGHT: 1px solid; BORDER-TOP: 1px solid; BORDER-LEFT: 1px solid; WIDTH: 77.46%; BORDER-BOTTOM: 1px solid; HEIGHT: 26px" size="71"> <input style="BORDER-RIGHT: #999999 1px solid; BORDER-TOP: #999999 1px solid; FONT-SIZE: 15pt; BORDER-LEFT: #999999 1px solid; WIDTH: 103px; BORDER-BOTTOM: #999999 1px solid; HEIGHT: 28px" onclick="WorcChangeHtml()" runat="server" id="btnUpLoad" type="submit" value="导入" name="btnUpLoad"> <textarea style="WIDTH: 15.25%; HEIGHT: 23px" rows="50" cols="16" id="txtIdea" runat="server">
其中txtIdea中的值就是客户端Word中的内容了,注意:需要调整IE的安全性设置,否则将无效.
