问题
Trying to load remote images into a flash sideshow local files work even if I use absolute path. I am updating existing gallery to dynamically pull images from Picasa.
The php works fine and pulls the images from the API. http://domaineseattle.com/gallery/FlashPhotoStack_SRC/gallery.php
But when I pass the XML to flash it wont load remote images.
I added
System.security.loadPolicyFile("http://photos.googleapis.com/data/crossdomain.xml");
to ActionScript but it still wont work.
The scrip for the sideshow is:
1
System.security.loadPolicyFile("http://photos.googleapis.com/data/crossdomain.xml");
System.security.allowDomain("*");
MovieClip.prototype.addProperty("onLoad", function () {
return __onLoadHandler__[this];
}, function (f) {
if (__onLoadHandler__ == undefined) {
_global.__onLoadHandler__ = {};
}
__onLoadHandler__[this] = f;
});
Math.easeInQuad = function(t, b, c, d) {
return c*(t /= d)*t+b;
};
Math.easeOutQuad = function(t, b, c, d) {
return -c*(t /= d)*(t-2)+b;
};
Stage.scaleMode = "noScale";
myXML = new XML();
myXML.ignoreWhite = true;
myXML.onLoad = function() {
nodes = myXML.childNodes;
// ----------------------
// find first image
// ----------------------
if (topimage.length) {
for (var i = 0; i<nodes.length; i++) {
if (nodes[i].attributes.src == topimage) {
var insert = nodes.slice(0, i);
nodes.splice(0, i);
nodes = nodes.concat(insert);
}
}
}
_root.gotoAndStop(2);
};
//if (_url.indexOf("http")>-1) {
myXML.load("gallery.php");
//} else {
// myXML.load("gallery.xml");
//}
stop();

System.security.loadPolicyFile("http://photos.googleapis.com/data/crossdomain.xml");
System.security.allowDomain("*");

this._y = Math.easeOutQuad(this.t, goy, -goy, 6);
if (this.t == 6) {

}
};
}
};
// Rotate the next image into view
stack[1]._x = stack[1]._y=0;
stack[1].t = 0;
stack[1].rot = stack[1]._rotation;
stack[1].onEnterFrame = function() {

if (this.t == 6) {
delete this.onEnterFrame;
}
};
// Move top image to the back of the stack array
var addback = stack.shift();
stack.push(addback);
};
Any help would be greatly appreciated.
Thanks!
回答1:
Does it work when you run it directly from the flash ide? In that case you are almost sure it is a permission/security issue, flash flat out refusing to load the images. If it also does not work directly from the flash ide I'd recommend putting some trace statements to print out the urls of the images that it it loading so you can check that they are actually getting parsed correctly (or use the debugger to achieve the same).

Ok so I decided to move on from the old AS 1.1 script I was having trouble with and ended up just purchasing http://flash-gallery.com/stack-photo-gallery/. It has everything I needed to get the project done. Thanks for your answers I really appreciate it.
