announce_party.js

announce_party: function(cb_name, info)
    {
    	info = this.parse_flash_args(info);
    	var publishHref = window.location.href.split('?')[0];
    	var chr;
    	if (info.screen != '' && info.screen != undefined)
    	{
    		if (publishHref.indexOf("?")!=-1) {
    			chr = "&";
    		}
    		else {  
    			chr = "?";
    		}	
    		publishHref += chr + "target_screen=" + info.screen + "_" + this.id; 
    	}
    	FacebookJSInterface.stream_publish(cb_name, info.prompt, info.userMessage, info.attachmentName, info.attachmentCaption, info.attachmentDescription, publishHref, info.imageURL);
    },
