I need to use the operator ~ in client elements like is used in asp.net server controls.
By example :
1)Writing javascript code: parent.location.href('~/Pages/Test.aspx');
2)body1.Style.Add("background-image",url(~/imagens/back_logo_co.jpg)");

I was using Request.ApplicationPath but not worked.

Thanks for your help.

The tilde only works on the server side. One way I have do it is to make a global javascript variable in the page that gets set with the application root by the server... something like this:

RegisterStartupScript(string.Format("<script language=\"javascript\">var _strAppRoot=\"{0}\";</script>", ResolveUrl("~"));

That should put this on the page:

<script language="javascript">var _strAppRoot="/MyApplicationName";</script>

You can then use that global var anywhere in your script to resolve a page or resource path on the client.

Dear Peter,

The Microsoft documentation sometimes is difficult to find alternatives options.
By example: I was seeking the ~ asp.net operator and doesn’t have any link alternative documentation to find ResolveClientUrl or ResolveUrl.

Thanks a lot!
