js如何读取客户端Excel文件
详细见 http://www.oejia.net/blog/2012/08/07/Js_read_xls.html
原理是利用了IE关于Excel的ActiveX插件,所以此功能只支持IE系列浏览器
var tempStr = ""; var filePath= document.all.upfile.value; var oXL = new ActiveXObject("Excel.application"); var oWB = oXL.Workbooks.open(filePath); oWB.worksheets(1).select(); var oSheet = oWB.ActiveSheet; try{ for(var i=2;i<46;i++){ if(oSheet.Cells(i,2).value =="null" || oSheet.Cells(i,3).value =="null" ) break; var a = oSheet.Cells(i,2).value.toString()=="undefined"?"":oSheet.Cells(i,2).value; tempStr+=(" "+oSheet.Cells(i,2).value+ " "+oSheet.Cells(i,3).value+ " "+oSheet.Cells(i,4).value+ " "+oSheet.Cells(i,5).value+ " "+oSheet.Cells(i,6).value+"\n"); } }catch(e){ document.all.txtArea.value = tempStr; } document.all.txtArea.value = tempStr; oXL.Quit(); CollectGarbage();
