Application.ExternalEval - variable for links to reuse for multiple objects

Question

hi,

I would to reuse this script

 function OnMouseDown():void {
     Application.ExternalEval("window.open('http://www.google.com')");
 }

for multiple objects with different links ... I'm trying to pass the web link from the variable but it doesn't work!

 var setURL = '';
 
 function OnMouseDown():void {
     Application.ExternalEval("window.open(setURL)");
 }

suggestions? thanks!

Don't mix up different contexts. Unity's scripting environmant is completely seperated from the website the player runs in. You can't use a variable defined in Unity in webpage javascript, but you can pass the content of that variable like this:

var setURL = '';

function OnMouseDown():void {
    Application.ExternalEval("window.open('" + setURL + "')");
}

still doesn't work...

 var setURL : String = "http://www.google.it";
 
 function OnMouseDown():void {
     Application.ExternalEval("window.open(" + setURL + ")");
 }

Well, it looks to me like you're missing some quotes:

 Application.ExternalEval("window.open('" + setURL + "')");

Doh! :D My bad... forgot it's a string. I will fix it (but it may take a while until it's visible...)
