I know this is old but to anyone interested, just add onclick and it will work fine. The extra attribute (even though it doesn't show up on intellisense) will pass through to the rendered markup.
我知道这很旧，但对于任何感兴趣的人，只需添加 onclick 即可正常工作。额外的属性（即使它没有出现在智能感知上）将传递到呈现的标记。
<asp:HyperLink ID="HyperLink4" runat="server" onclick="logDownload();" NavigateUrl="~/download/Sample-Icons.zip">Download Icons</asp:HyperLink>

If you use a LinkButtoninstead, you can use the OnClientClickproperty to execute a JavaScript function. Using the HyperLinkcontrol, you can use the NavigateUrlproperty like this:
如果使用 aLinkButton代替，则可以使用该OnClientClick属性来执行 JavaScript 函数。使用HyperLink控件，您可以NavigateUrl像这样使用属性：
<asp:HyperLink ID="Link1" runat="server"
Text="Click Me!"
NavigateUrl="javascript:OpenImage('App_Themes/White/Images/thmb_screenshot_1.png');">
</asp:HyperLink>

I know this is old, but for anyone looking to do this on the server side and not through the markup, you can do.
我知道这很旧，但是对于希望在服务器端而不是通过标记执行此操作的任何人，您都可以做到。
var hyperLink = new HyperLink { Text = "Display text", ID = "hyperlinkId"};
hyperLink.Attributes.Add("onclick", "javascriptMethod()");

It looks like you are basically there, what's wrong with this?
看起来你基本上就在那里，这有什么问题？
<asp:HyperLink ID="Hyperlink" runat="server" OnClientClick="OpenImage(this.src)" />
