如何将JavaScript添加到ASP.NET超链接控件

Question

How can I enter this URL into a HyperLink ASP.NET Control ?

<a href="https://plus.google.com/share?url={URL}" 
   onclick="javascript:window.open(this.href,'','menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');return false;">
    <img src="https://www.gstatic.com/images/icons/gplus-64.png" alt="Share on Google+"/>
</a>

Answer 1

Just use onclick . Any properties that are not recognized by ASP.Net are passed as-is.

<asp:HyperLink ID="HyperLink1" runat="Server"
    NavigateUrl="https://plus.google.com/share?url={URL}"
    onclick="javascript:window.open(this.href, '',
      'menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');
      return false;">
  ...
</asp:HyperLink>

In general, if you don't need server-side access to a control, I wouldn't recommend converting them to server-side because it adds extra unnecessary processing to the server.

Answer 2

To add it in the declarative syntax just add it ie

<asp:HyperLink 
    runat="server" 
    ID="theLink" 
    onclick="javascript:window.open(this.href, '','menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');
  return false;">
</asp:HyperLink>

You must note that OnClick (which is event binding for ASP.NET and the lowercase version onclick are NOT the same)

If you want to do it in code behind then you can do it via the WebControl.Attributes array ;)
