Open a link without popup-blocker

Questions & Answers

Hi.
I want to create a button which opens a link to a new webpage. Currently I use the following inside of a OnMouseDown method:

Application.ExternalEval("window.open('" + url + "','_blank')");

However this gets rightfully blocked by any popup blocker. I’ve done some research and found out, that the blocker only allows this when the funktion was called by a user event like the onclick event.

Outside of unity you could use the events like this (in a form class):

private Button someButton;
private EventHandler buttonEvent;

//inside of the constructor:
buttonEvent = new EventHandler(buttonFunktion);
someButton = new Button();
someButton.Click += newFormEvent;

private void buttonFunktion(object o, eventArgs e){}

My problem is that I have no idea how I could access the events which get fired when I press a mouse button over a collider.

If your WebPlayer knows which page it’s going to be shown on, you can call JavaScript that’s on that page.

The Unity manual offers a pretty simple example, which I’ll quote below.

Example page contains the following JS:

<script type="text/javascript" language="javascript">
<!--
function SayHello( arg )
{
    // show the message
    alert( arg );
}
-->
</script>

Example WebPlayer app calls the following:

Application.ExternalCall( "SayHello", "The game says hello!" );
