js讀取本地excel文檔資料的代碼_javascript技巧

複製代碼 代碼如下:

<script>
function readThis(){
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){
//alert(e);
document.all.txtArea.value = tempStr;
}
document.all.txtArea.value = tempStr;
oXL.Quit();
CollectGarbage();
}
</script>
<html>
<input type="file" id="upfile" /><input type="button" onclick="readThis();" value="讀取">
<br>
<textarea id="txtArea" cols=50 rows=10></textarea>
</html>

以上代碼在需要設定IE安全層級低才能正常運行，貼出來主要是可以學習這方面的技術
