推荐答案

我实际上用一个有趣的技巧解决了这个问题.这就是...

I actually solved this problem with an interesting trick. Here's how...

创建一个名为vbshelper.inc的外部vbscript include file，其中包含以下代码:

Create an external vbscript include file called vbshelper.inc which contains the following code:

function stuffKeys(x)
     Set wshShell = CreateObject("WScript.Shell")
    wshShell.Sendkeys(x)
end function

在您的HTML代码标题中，将以下行作为您的第一个>元素...

---

Inside your HTML code header, place the following line as your first < Script> element...

< Script type="text/VBScript src="vbshelper.inc">

稍后，在您的HTML代码中，像这样创建按钮...

later, in your HTML code, create the button like this...

< input type="File" id="srcFile" onchange="go_do_something()" onclick="stuffkeys(' C:\Temp\*.txt~')">

请注意' C:\Temp*.txt~'中C之前的空格和.txt之后的波浪号~.

Note the space before the C in ' C:\Temp*.txt~' and the tilde ~ after the .txt.
