Is there any way, using Google Apps Script, to create a link (with arguments) that will open in the same window on a Google Sites page?
I have explored an embedded gadget using UiApp (createAnchor), an embedded gadget using HtmlService, and an embedded gadget where the links were constructed to point at the web-app URL of the application rather than the parent page of the embedded gadget.
Either the link opens in a new window (UiApp, and HtmlService when I included "target=_blank" in the link), or it loads in the iframe of the gadget (HtmlService), or it strips the arguments from the link address (web-app URL).
I'm at a loss. How do people go about creating dynamic content that contains links (for instance: menus) for google sites?
