You can communicate between frames via the message posting API. For example, in your child frame you might call: parent.postMessage(“child frame”, “*”); And in the parent frame, register a message handler: window.addEventListener(“message”, function(event) { console.log(“Hello from ” + event.data); });
There are 3 ways to allow cross domain origin (excluding jsonp): Set the header in the page directly using a templating language like PHP. Keep in mind there can be no HTML before your header or it will fail. Modify the server configuration file (apache.conf) and add this line. Note that “*” represents allow all. … Read more
Update In newer versions of THREE.js cross origin images are handled by default. THREE.ImageUtils.loadTexture is deprecated. It’s common to use TextureLoader const loader = new THREE.TextureLoader(); const mapOverlay = loader.load(‘http://i.imgur.com/3tU4Vig.jpg’); Original Answer This works THREE.ImageUtils.crossOrigin = ”; var mapOverlay = THREE.ImageUtils.loadTexture(‘http://i.imgur.com/3tU4Vig.jpg’); Here’s a sample var canvas = document.getElementById(“c”); var renderer = new THREE.WebGLRenderer({canvas: canvas}); var … Read more
I use gorilla/mux package to build Go RESTful API server, and client use JavaScript Request can work, My Go Server runs at localhost:9091, and the Server code: router := mux.NewRouter() //api route is /people, //Methods(“GET”, “OPTIONS”) means it support GET, OPTIONS router.HandleFunc(“/people”, GetPeopleAPI).Methods(“GET”, “OPTIONS”) log.Fatal(http.ListenAndServe(“:9091”, router)) I find giving OPTIONS here is important, otherwise error … Read more
It is generally bad practice to embed an iframe with content served over HTTPS within a page served over plain HTTP (or mix content). The reason for this is that there’s no good way for the user to check they’re using the HTTPS site they intend (unless the user really wants to check the source … Read more
For two documents to be considered to have the same origin, the protocol (http/https), the domain and the port (the default 80 or :xx) have to be indentical. So no, you cannot use xhr against a different port.
There are a lot of possible issues. Try with one of these solutions: protocols must be the same (so the page that attempts to access the iframe must have the same protocol of the site that deliver the iframe), so if you are testing your app in sandbox mode (http instead of https), disable the … Read more
Try to use JSONP in your Ajax call. It will bypass the Same Origin Policy. http://learn.jquery.com/ajax/working-with-jsonp/ Try example $.ajax({ url: “https://api.dailymotion.com/video/x28j5hv?fields=title”, dataType: “jsonp”, success: function( response ) { console.log( response ); // server response } });
JSONP or “JSON with padding” is a communication technique used in JavaScript programs running in web browsers to request data from a server in a different domain, something prohibited by typical web browsers because of the same-origin policy. JSONP takes advantage of the fact that browsers do not enforce the same-origin policy on script tags. … Read more
Almost everywhere you look, people refer to the about:config and the security.fileuri.strict_origin_policy. Sometimes also the network.http.refere.XOriginPolicy. For me, none of these seem to have any effect. This comment implies there is no built-in way in Firefox to do this (as of 2/8/14).
