但是，如果我們怎么用javascript怎么打開呢？其實，也不難。
二.在javascript打開word文檔
我們新建一個html文件，并且寫一個FileUpLoad以及button控件。

復制代碼代碼如下:

 
<input id="flUpload" type="file" />flUpload 
<input id="btnOpenFile" type="button" value="button" onclick="OpenFile()" /> 

然后，在寫一個javascript OpenFile方法。

復制代碼代碼如下:

 
function OpenFile() 
{ 
if (document.getElementById("flUpload").value.toUpperCase().indexOf(".XLS") != -1) 
{ 
var objExcel; 
objExcel = new ActiveXObject("Excel.Application"); 
objExcel.Visible = true; 
objExcel.Workbooks.Open(document.getElementById("flUpload").value); 
} 
else if (document.getElementById("flUpload").value.toUpperCase().indexOf(".DOC") != -1) 
{ 
var objDoc; 
objDoc = new ActiveXObject("Word.Application"); 
objDoc.Visible = true; 
objDoc.Documents.Open(document.getElementById("flUpload").value); 
} 
else 
{ 
alert("Please select Word/Excel file only"); 
return false; 
} 
}
