在前端获取上传的excel文件内容

function ReadExcel() {var tempStr = "";//得到文件路径的值var filePath = document.getElementById("upfile").value;//创建操作EXCEL应用程序的实例var oXL = new ActiveXObject("Excel.application");//打开指定路径的excel文件var oWB = oXL.Workbooks.open(filePath);oWB.worksheets(1).select();var oSheet = oWB.ActiveSheet;var nRows = oSheet.usedrange.rows.count;var nColumns = oSheet.usedrange.columns.count;for(var i = 1; i < nRows; i++) {for(var j = 0; j < nColumns; j++) {if(oSheet.Cells(i + 1, j + 1).value == undefined) {console.log(" ");} else {console.log(oSheet.Cells(i + 1, j + 1).value);}}}//退出操作excel的实例对象oXL.Application.Quit();//手动调用垃圾收集器CollectGarbage();}
