How do I hide a button from external javascript

Hello together

I have a javascript which should show a button. Only when user ist set the button should be shown.

  var url = document.URL;
  var user = url.split("&user=");
  if(user != "") {
  user = user[1].split("&");
  }

  if(user[0] != "NOUSER" && user[0] != "") {
  // Show Button
  }[/code:20409sjf]

So now my question is how can I add this function to Construct 2, so that a button is set to invisible.

GREETS

Using the "Button set invisible" action?

Actually if you want the button invisible on start you could choose to set it invisible in it's properties and only set it visible when needed, or create the button object when needed using a system create action.

I'm not sure why you would want to use an external script for that..

Ok and how can I check if the user variable is set in Construct2?

System compare variable User is not ""

You might want to look at some tutorials and read the manual..

But I don't have the variable in Construct 2. it's only a browser url parameter

Through the browser object you can get all the info you want..

Browser.Title

The current HTML document's title.

Browser.Domain

The current domain, e.g. scirra.com.

Browser.Hash

The string after the hash at the end of the URL, including the hash. For example, if the current URL is http://scirra.com/mygame/index.html#teapot, this returns #teapot.

Browser.PathName

The path relative to the domain in the URL. For example the path name of http://scirra.com/mygame/index.html#teapot is /mygame/index.html.

Browser.Protocol

The current protocol, usually either http: or https:.

Browser.QueryParam

Return a query string parameter by name. For example, if the URL ends with index.html?foo=bar&baz=wan, QueryParam("foo") returns bar and QueryParam("baz") returns wan.

Browser.QueryString

Return the full URL query string including the question mark. For example, if the URL ends with index.html?foo=bar&baz=wan, this returns ?foo=bar&baz=wan.

Browser.Referrer

Get the previous page that linked to this page, if any.

Browser.URL

Get the complete current URL in the browser address bar, including the protocol.
