    copied!<p>I am sending a message like this:</p> <pre><code>self.port.emit("nodes_grubed", textNodesValues); </code></pre> <p>And want to react to it:</p> <pre><code>worker.port.on("nodes_grubed", requestRenderedtext); </code></pre> <p>But it doesn't work. What should I change? You can try my add-on <a href="https://builder.addons.mozilla.org/addon/1051796/latest/" rel="nofollow">here</a>.</p> <p><code>main.js</code>:</p> <pre><code>var widgets = require("widget"); var tabs = require("tabs"); var self = require("self"); function requestRenderedtext(textNodesText) { console.log('text nodes requesting'); } var widget = widgets.Widget({ id: "mozilla-link", label: "Mozilla website", contentURL: "http://www.mozilla.org/favicon.ico", onClick: function(worker) { tabs.activeTab.attach({ contentScriptFile: self.data.url("process.js") }); worker.on("nodes_grubed",requestRenderedtext); worker.port.on("nodes_grubed",requestRenderedtext); }, onAttach: function(worker) { worker.on("nodes_grubed",requestRenderedtext); worker.port.on("nodes_grubed",requestRenderedtext); } }); widget.on("nodes_grubed",requestRenderedtext); widget.port.on("nodes_grubed",requestRenderedtext); </code></pre> <p><code>process.js</code>:</p> <pre><code>function getTextNodes() { var walker = document.createTreeWalker( document.body, NodeFilter.SHOW_TEXT, null, false ); var node; textNodes = []; var textNodesValues=[]; while(node = walker.nextNode()) { if (node.parentNode.tagName!='SCRIPT') { textNodesValues.push(node.nodeValue); textNodes.push(node) } } if (textNodesValues.length!=0) { console.log('emmiting nodes'); self.port.emit("nodes_grubed", textNodesValues); } } getTextNodes(); </code></pre>
