可以读取EXCEL文件的js代码

阅读更多
js读取 EXCEL 文件 的实现代码,比较全了大家可以自行测试了。
首页给个有中文说明的例子,下面的例子很多大家可以多测试。
复制代码 代码如下:
<script language="javascript" type="text/javascript"><!--
function readExcel() {
var excelApp;
var excelWorkBook;
var excelSheet;
try{
excelApp = new ActiveXObject("Excel.Application");
excelWorkBook = excelApp.Workbooks.open("C:\\XXX.xls");
excelSheet = oWB.ActiveSheet; //WorkSheets("sheet1")
excelSheet.Cells(6,2).value;//cell的值
excelSheet.usedrange.rows.count;//使用的行数
excelWorkBook.Worksheets.count;//得到sheet的个数
excelSheet=null;
excelWorkBook.close();
excelApp.Application.Quit();
excelApp=null;
}catch(e){
if(excelSheet !=null || excelSheet!=undefined){
excelSheet =nul;
}
if(excelWorkBook != null || excelWorkBook!=undefined){
excelWorkBook.close();
}
if(excelApp != null || excelApp!=undefined){
excelApp.Application.Quit();
excelApp=null;
}
}
// --></script>

复制代码 代码如下:
如果是在网页上打开EXCEL 文件,那么在关闭的时候,进程里还有EXCEL.EXE,所以必须关闭后,刷新本页面!
<script>
function ReadExcel()
{
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();
}
</script>
<html>
<input type="file" id="upfile" /><input type="button" onclick="ReadExcel();" value="read">
<br>
<textarea id="txtArea" cols=50 rows=10></textarea>
</html>

二、
js读取excel文件
复制代码 代码如下:
<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="读取"><br>
<textarea id="txtArea" cols=50 rows=10></textarea>
</html>

三、
我在vs2005平台上要实现这么一个功能,点击一个按钮一次将大量的excel文件数据导入到sqlserver2005中
我用的是ajax技术,在前台用javascript操做excel文件,循环读取所有的excel文件,每读取一行就放进一个数组里通过web服务传到后台用c#语言将一行数据插入到数据库。思路大概就是这样。
现在功能已经实现了,具体代码如下
用javascript定义一个函数,循环读取excel文件数据
复制代码 代码如下:
function readExcel()
{
try
{
var ExcelNum=new Array();
//重复导入之前,删除上次导入的同期数据
WebServiceExcel.deleteOldNumber();
var oXL = new ActiveXObject( "Excel.Application ");
\\r_c_num[5]的值为excel文件的名字
var path=document.all.excelpath.value+ "\\ "+r_c_num[5]
var oWB = oXL.Workbooks.open(path);
\\如果excel文件有多个sheet的话从第一个sheet循环读取
for(var x=1;x <=oWB.worksheets.count;x++)
{
oWB.worksheets(x).select();
var oSheet =oWB.ActiveSheet;
\\按指定开始行和开始列读取excel文件的数据
for(var i=parseInt(r_c_num[6]);i <=parseInt(r_c_num[7]);i++)
{
for(var j=parseInt(r_c_num[8]);j <=parseInt(r_c_num[9]);j++)
{
if(typeof(oSheet.Cells(i,j).value)== "undefined ")
{
ExcelNum[j-parseInt(r_c_num[8])+6]= " ";
}
else
{
switch_letter(j);
ExcelNum[j-parseInt(r_c_num[8])+6]=oSheet.Cells(i,j).value;
}
}
//将读取的一行数据传到后台插入到数据库
WebServiceExcel.insert_From_Excel(ExcelNum);
}
}
}
}
catch(err)
{
alert( "出错了, "+err.message);
}
}

这只是前台的关键代码。
现在的问题是,如果excel文件数据太多的话,导入过程要等好长时间,性能太差了,不知道该怎么改进???如果导几千行数据就不行了,时间让我无法忍受。请高手赐教,很着急用,谢谢了!!!

var oXL=null;
try{
oXL = new ActiveXObject("Excel.Application");
}catch(e){
alert(e.message);
return ;
}
if (oXL == null){
alert("创建Excel文件失败,可能是您的计算机上没有正确安装Microsoft Office Excel软件或浏览器的安全级别设置过高!");
return;
}
try{
// Get a new workbook.
oWB = oXL.Workbooks.Open(excelFileName);
for (i = 1; i <= oWB.Sheets.Count; i++){
if (oWB.Sheets(i).name.lastIndexOf("月") != -1){
showSheet(i);
}
}
}
catch (e){
alert(e.message);
}
oWB.Close();   //不close工作簿的话,后果还是挺严重的。
oWB = null;
oXL = null;
}
function showSheet(sheetNO){
var oSheet = oWB.Sheets(sheetNO);
document.write("<table border=1>");
for (i = 1; i < oSheet.UsedRange.Rows.Count; i++){
document.write("<tr>");
for (j = 1; j < oSheet.UsedRange.Columns.Count; j++){
value = oSheet.Cells(i, j).Value;
if (value == undefined){
value = " ";
}
document.write(i == 1 ? "<th nowrap=true><b>" : "<td>");

flash的听说不太完美,
pdf的我找到一个。。。此时还是个测试版,

如果有完美的js可操纵office全套和pdf就好了,可以把flash踢掉。



# PDF.JS


pdf.js is an HTML5 technology experiment that explores building a faithful
and efficient Portable Document Format (PDF) renderer without native code
assistance.

pdf.js is community-driven and supported by Mozilla Labs. Our goal is to
create a general-purpose, web standards-based platform for parsing and
rendering PDFs, and eventually release a PDF reader extension powered by
pdf.js. Integration with Firefox is a possibility if the experiment proves
successful.



# Getting started

### Online demo

For an online demo, visit:

+ http://mozilla.github.com/pdf.js/web/viewer.html

This demo provides an interactive interface for displaying and browsing PDFs
using the pdf.js API.

### Extension

A Firefox extension is availble in two places:

+ Stable Version: https://addons.mozilla.org/firefox/addon/pdfjs
+ Development Version: http://mozilla.github.com/pdf.js/extensions/firefox/pdf.js.xpi

The development extension should be quite stable but still might break from time to time.
Also, note that the development extension is updated on every merge and by default Firefox will
auto-update extensions on a daily basis (you can change this through the
`extensions.update.interval` option in `about:config`).

For an experimental Chrome extension, get the code as explained below and issue `node make extension`.
Then open Chrome, go to `Tools > Extension` and load the (unpackaged) extension
from the directory `build/chrome`.

### Getting the code

To get a local copy of the current code, clone it using git:

    $ git clone git://github.com/mozilla/pdf.js.git pdfjs
    $ cd pdfjs

Next, you need to start a local web server as some browsers don't allow opening
PDF files for a file:// url:

    $ node make server

You can install Node via [nvm](https://github.com/creationix/nvm) or the
[official package](http://nodejs.org). If everything worked out, you can now serve

+ http://localhost:8888/web/viewer.html

You can also view all the test pdf files on the right side serving

+ http://localhost:8888/test/pdfs/?frame

### Building pdf.js.

In order to bundle all `src/` files into a final `pdf.js` and build the generic viewer, issue:

    $ node make generic

This will generate the file `build/generic/build/pdf.js` that can be included in your final project. The pdf.js file is large and should be minified for production. Also, if you would like to support more browsers than firefox you'll also need to include `compatibility.js` from `build/generic/web/`.


# Learning

You can play with the PDF.js API directly from your browser through the live demos below:

+ Hello world: http://jsbin.com/pdfjs-helloworld-v2/edit#html,live
+ Simple reader with prev/next page controls: http://jsbin.com/pdfjs-prevnext-v2/edit#html,live

The repo contains a hello world example that you can run locally:

+ [examples/helloworld/](https://github.com/mozilla/pdf.js/blob/master/examples/helloworld/)

For an introduction to the PDF.js code, check out the presentation by our contributor Julian Viereck:

+ http://www.youtube.com/watch?v=Iv15UY-4Fg8

Additional learning resources can be found at:

+ https://github.com/mozilla/pdf.js/wiki/Additional-Learning-Resources


# Contributing

pdf.js is a community-driven project, so contributors are always welcome.
Simply fork our repo and contribute away. Good starting places for picking
a bug are the top error messages and TODOs in our corpus report:

+ http://people.mozilla.com/~bdahl/corpusreport/test/ref/

and of course our open Github issues:

+ https://github.com/mozilla/pdf.js/issues

For better consistency and long-term stability, please do look around the
code and try to follow our conventions.
More information about the contributor process can be found on the
[contributor wiki page](https://github.com/mozilla/pdf.js/wiki/Contributing).

If you don't want to hack on the project or have little spare time, __you still
can help!__ Just open PDFs in the
[online demo](http://mozilla.github.com/pdf.js/web/viewer.html) and report
any breakage in rendering.

Our Github contributors so far:

+ https://github.com/mozilla/pdf.js/contributors
+ https://github.com/mozilla/pdf.js/blob/master/LICENSE

You can add your name to it!


# Running the tests

pdf.js comes with browser-level regression tests that allow one to probe
whether it's able to successfully parse PDFs, as well as compare its output
against reference images, pixel-by-pixel.

More information about running the tests can be found on the
[contributor wiki page](https://github.com/mozilla/pdf.js/wiki/Contributing).
