您不能直接在vb.net代码中编写javascript.但是，您可以从vb.net代码注册并触发javascript.

you can not write javascript directly in vb.net code. However you can register and fire javascript from vb.net code.

尝试一下

Page.RegisterClientScriptBlock("key","<script>alert('Hello World');</script>");

尝试使用此vb代码块:

Try this vb code block:

Dim strScript As String = "<script>"
strScript += "alert('Hello, Pavan');"
strScript += "</script>"
Page.RegisterClientScriptBlock("strScript", strScript)
