Office xp之后的版本支持通过webdav协议(http的扩展)直接编辑服务器上的文件。
IIS(6.0)支持webdav,这在IIS管理器的web服务扩展中可以看到.利用IIS作为webdav的服务器端,可以很容易的实现office(word,excel等)的在线编辑.
可以简单的实验一下:
确保IIS的webdav扩展安装并被启用了,建立一个虚拟目录test,在其中放一个word文档a.doc,然后打开word, 文件->打开->输入word文档的访问url(http://localhost/test/a.doc),
修改一下文档内容,保存一下,发生了什么? 文档被保存到服务器上了.
在IE中,可以通过js创建Word.Application,来打开,修改服务器上的文档.
wApp
=
new
ActiveXObject(
"
Word.Application.11
"
);
wApp.Visible = true ;
wApp.Documents.Open( url );
if ( trackRevisions ){ //可以实现痕迹保留呢
wApp.ActiveDocument.TrackRevisions = true ;
wApp.ActiveDocument.ShowRevisions = false ;
} else
{
wApp.ActiveDocument.TrackRevisions = false ;
wApp.ActiveDocument.ShowRevisions = false ;
}
wApp.ActiveDocument.Application.UserName = Global_CurrentUserName;
wApp.Visible = true ;
wApp.Documents.Open( url );
if ( trackRevisions ){ //可以实现痕迹保留呢
wApp.ActiveDocument.TrackRevisions = true ;
wApp.ActiveDocument.ShowRevisions = false ;
} else
{
wApp.ActiveDocument.TrackRevisions = false ;
wApp.ActiveDocument.ShowRevisions = false ;
}
wApp.ActiveDocument.Application.UserName = Global_CurrentUserName;
另外,安装office时,会同时按装一个ActiveX组件:Sharepoint.OpenDocuments,可么用此组件来激活word,编辑服务器上的文档:
var
__OpenDocuments
=
null
;
function Document_Edit2( url )
{
if ( __OpenDocuments == null )
{
try {
__OpenDocuments = new ActiveXObject( " SharePoint.OpenDocuments.3 " ); //for office 2007
} catch (e){}
if ( __OpenDocuments == null || typeof (__OpenDocuments) == " #ff0000 " )
{
try {
__OpenDocuments = new ActiveXObject( " SharePoint.OpenDocuments.2 " ); //for office 2003
} catch (e){}
}
if ( __OpenDocuments == null || typeof (__OpenDocuments) == " undefined " )
{
alert( " 请安装Word(2003或更高版本) " );
return ;
}
}
// openDocObj.ViewDocument("http://www.abc.com/documents/sample.doc");, "Word.Document"
// openDocObj.CreateNewDocument("http://www.abc.com/documents/sampleTemplate.dot", "http://www.abc.com/documents/");
var result = __OpenDocuments.EditDocument( url , " Word.Document " );
if ( result == false )
{
alert( " 无法打开文档. " );
}
}
function Document_Edit2( url )
{
if ( __OpenDocuments == null )
{
try {
__OpenDocuments = new ActiveXObject( " SharePoint.OpenDocuments.3 " ); //for office 2007
} catch (e){}
if ( __OpenDocuments == null || typeof (__OpenDocuments) == " #ff0000 " )
{
try {
__OpenDocuments = new ActiveXObject( " SharePoint.OpenDocuments.2 " ); //for office 2003
} catch (e){}
}
if ( __OpenDocuments == null || typeof (__OpenDocuments) == " undefined " )
{
alert( " 请安装Word(2003或更高版本) " );
return ;
}
}
// openDocObj.ViewDocument("http://www.abc.com/documents/sample.doc");, "Word.Document"
// openDocObj.CreateNewDocument("http://www.abc.com/documents/sampleTemplate.dot", "http://www.abc.com/documents/");
var result = __OpenDocuments.EditDocument( url , " Word.Document " );
if ( result == false )
{
alert( " 无法打开文档. " );
}
}
可以看到,基于IIS的webdav支持,可以非常简单的实现office文档的在线编辑, 但有一个问题:这样,文档是存放在文件系统上,我们很多系统中,
文档是存放在数据库中的,这样一来,如何实现呢???
I tried a lot and found the solution. It will be in the next article .
