Building upon the answers by LyphTEC and Akrikos, another work-around is to create an </code> within a blank popup window, which avoids the need for a separate proxy page, since the blank popup has the same origin as its opener.</p> <p><strong>Launcher page at <code>http://example.com/launcher.htm</code></strong></p> <pre><code><html> <head> <title>postMessage launcher</title> <script> function openWnd() { var w = window.open("", "theWnd", "resizeable,status,width=400,height=300"), i = w.document.createElement("iframe"); i.src = "http://example.net/remote.htm"; w.document.body.appendChild(i); w.addEventListener("message", function (e) { console.log("message from " + e.origin + ": " + e.data); // Send a message back to the source e.source.postMessage("reply", e.origin); }); } </script> </head> <body> <h2>postMessage launcher</h2> <p><a href="javascript:openWnd();">click me</a></p> </body> </html> </code></pre> <p><strong>Remote page at <code>http://example.net/remote.htm</code></strong></p> <pre><code><html> <head> <title>postMessage remote</title> <script> window.addEventListener("message", function (e) { alert("message from " + e.origin + ": " + e.data); }); // Send a message to the parent window every 5 seconds setInterval(function () { window.parent.postMessage("hello", "*"); }, 5000); </script> </head> <body> <h2>postMessage remote</h2> </body> </html> </code></pre> <p>I'm not sure how fragile this is, but it is working in IE 11 and Firefox 40.0.3.</p> </p> <div class="appendcontent"> </div> </div> <div class="jieda-reply"> <span class="jieda-zan button_agree" type="zan" data-id='438725'> <i class="iconfont icon-zan"></i> <em>0</em> </span> <span type="reply" class="showpinglun" data-id="438725"> <i class="iconfont icon-svgmoban53"></i> 讨论(0) </span> <div class="jieda-admin"> </div> <div class="noreplaytext bb"> <center><div> <a href="https://www.e-learn.cn/qa/q-107512.html"> 查看其它8个回答 </a> </div></center> </div> </div> <div class="comments-mod " style="display: none;
