动态设置文件输入的值
I have an input file HTML form and I want to set the initial value for the file path in an HTML form . I try to change tag "value" but it doesn't work anyway.
<input type="file" name="testcase" value= "C:\test.txt">
我有一个输入文件 HTML 表单，我想在 HTML 表单中设置文件路径的初始值。我尝试更改标签“值”，但无论如何都不起作用。
<input type="file" name="testcase" value= "C:\test.txt">
Please give me some advice for this small problem. Thanks.
请给我一些关于这个小问题的建议。谢谢。

From HTMLHelp.com:
来自HTMLHelp.com：
The file input type creates a field through which users can upload files from their local computer or network. The VALUE attribute specifies the name of the initial file, but it is typically ignored by browsers as a security precaution.
文件输入类型创建一个字段，用户可以通过该字段从本地计算机或网络上传文件。VALUE 属性指定初始文件的名称，但作为安全预防措施，浏览器通常会忽略它。
Therefore, setting an initial value is not supported.
因此，不支持设置初始值。
