You can use ClientScriptManager.RegisterStartupScript method.

Registers the startup script with the Page object using a type, a key, a script literal.

Code

 protected void btnsubmit_Click(object sender, EventArgs e)
 {
      string abc="xyz";       

      //If the string can contain apostrophes or backslashes, you would need to escape them
      string value = abc.Replace("\\", "\\\\").Replace("'", "\\'");
      Page.ClientScript.RegisterStartupScript(this.GetType(),"CallMyFunction","myfunction('" +value + "')",true);
 }
