Backwards compatible window. Message()January 1. Simple cross- domain messaging. This blog post explains how to implement a backwards compatible version of window. Message() to handle all your cross- domain messaging needs. If you’re in a hurry, you can skip directly to the demo or just grab the following files: Background. One of the trickiest things you will ever run into on the web is the same origin policy. I am calling the javascript window.open() function to load another url in a pop up. Once the users is finished it takes them to the last page that has a link that. A powerful Javascript/DHTML menu with a many of features, parameters. [Free for non-profit sites]. ![]() The same origin policy basically limits how scripts and frames on different domains can talk to each other. The same origin policy is an important part of your security on the web. For example, it prevents someone from being able to steal your password from another frame on the page. The annoying thing is there are sometimes perfectly valid reasons for frames on different domains to need to talk to one another. ![]() Is there an easy way to set a "callback" function to a new window that is opened in javascript? I'd like to run a function of the parent from the new window, but I. Code to cut and paste for a Demonstration page with Advanced Popup with Title, Image Size and Background Colour parameters <HTML> <HEAD> <TITLE>Java Popup Window. One good example of this would be the Facebook Connect library where facebook. Over the years we’ve developed a series of hacks to work around this browser limitation. Some developers have used flash while others have relied on a window. Facebook worked around it by getting people to install a cross domain communication channel. It got pretty ridiculous until the browser makers finally decided to give us a way to do cross- domain messaging without all the nonsense. The result was window. Message() which is supported by the latest browsers like Firefox 3, Safari 4, Chrome and IE 8. Unfortunately, as usual we’re going to need a backwards compatible version before we can take advantage of this new functionality. I found a couple great examples of people who have tackled this already. Luke Shepard wrote xd. Facebook Connect code. I also found Ben Alman’s j. Query plugin which does a really nice job. Both of these scripts are great, but neither fits quite right with my needs. For one, I wanted the smallest possible script written in pure Java. Script. I’m a fan of j. Query, but since I’ll be installing this code on other people’s domains I can’t assume that j. Query will be available and while I could load it up it’s important to keep the file size small. So what I did was start with Ben’s code and took out all of the j. Query dependencies. Here is the result: The code// everything is wrapped in the XD function to reduce namespace collisionsvar XD =function(){var interval_id,last_hash,cache_bust =1,attached_callback,window =this; return{post. Message : function(message, target_url, target){if(! Message']){// the browser supports window. Message, so call it with a target. Origin// set appropriately, based on the target_url parameter. Message'](message, target_url. Message, so use the window. Date)+(cache_bust++)+'& '+ message; }},receive. Message : function(callback, source_origin){// browser supports window. Messageif(window['post. Message']){// bind the callback to the actual event associated with window. Messageif(callback){attached_callback =function(e){if((typeof source_origin ==='string'& & e.Object. Boats And Birds Gregory And The Hawk Download Adobe here. String. call(source_origin)==="[object Function]"& & source_origin(e.Event.Listener']){window[callback ?'add.Event.Listener': 'remove.Mcafee Antivirus Sql Server Exclusions List here. Event': 'detach. Event']('onmessage', attached_callback); }}else{// a polling loop is started & callback is called whenever the location. Interval(interval_id); interval_id =null; if(callback){interval_id = set. Interval(function(){var hash = document. Usage: There are two parts to using this code: posting and listening. Both are relatively simple. To post a message we call XD. Message with a message, a URL and the frame that we want to talk to. Notice that we start off by passing the URL of the parent page to the child frame. This is important so the child knows how to talk back to the parent.// pass the URL of the current parent page to the iframe using location. URIComponent(document. Element. By. Id("xd_frame"). XD. post. Message(msg, src, frames[0]); returnfalse; }Setting up the listener on the child is also easy to do: var parent_url = decode. URIComponent(document. XD. receive. Message(function(message){window. I recommend taking a look at this barebones example to understand better how the various pieces fit together. This is still a work in progress and I’d love any feedback you have on it. I’m particularly interested in adding Flash as an alternative method before falling back to fragments. This is what the Facebook code does and I like it because it eliminates the nasty polling every 1. Got other thoughts on how to make this better? Let me know in the comments.
