  1. POHow do I output Jade content through JSON? (Node.js)
    text
    copied!<p>I wrote a video gallery web app a few months ago in CodeIgniter and I'm trying to move the back end to Node, using Express + Jade to produce the content. The PHP version sends JSON to the front end, often including a substantial chunk of HTML. </p> <p>I'd like to render the HTML bit with Jade (as that's what it's there for), but obviously I want to output it in JSON format and not straight to the browser. It may be painfully obvious how to do this, but I just can't figure it out at the moment... Any help very much appreciated. </p> <p><strong>Original PHP</strong></p> <pre><code>ob_start(); for ($i = $start; $i &lt; $end; $i++) { $v = $videos[$i]; echo '&lt;a id="video-' . $v-&gt;url . (isset($v-&gt;otherid) ? '-' . $v-&gt;otherid : '') . '" href="#!' . Settings::$pretty_link . '/' . $v-&gt;url . (isset($v-&gt;otherid) ? '/' . $v-&gt;otherid : '') . '" class="Box' . ($i == $start ? " Batch" : "") . '" title="Click to view the ' . $v-&gt;name . '"&gt;&lt;img src="' . site_url('images/thumb/' . $v-&gt;image) . '" alt="The ' . $v-&gt;name . '" /&gt;&lt;span&gt;' . $v-&gt;name . '&lt;/span&gt;&lt;/a&gt;'; } $data[$html] = ob_get_clean(); // Add some other things to $data echo json_encode($data); </code></pre> <p><strong>Shiny new Jade</strong></p> <pre><code>- var v - for (var i = view.start; i &lt; view.end; i++) { - v = view.videos[i] a(id="#{v.url + (v.otherid === null ? "" : "-" + v.otherid)}", href="#!#{settings.prettyLink + "/" + v.url + (v.otherid === null ? "" : "/" + v.otherid)}/", class="Box #{i == view.start ? "Batch" : ""}", title="Click to view the #{v.name}" ) img(src="#{settings.siteUrl}images/thumb/#{v.image}", alt="The #{v.name}") span #{v.name} - } </code></pre> <p>How do I do the <code>$data[$html] = ob_get_clean();</code> line? (And possibly also the <code>json_encode</code> one, though I currently have high hopes for <code>JSON.stringify</code>. :)</p> <p><strong>Edit</strong> As @loganfsmyth requested, the code used to render the Jade file (basically just the same as the Express examples). </p> <pre><code>res.render("search", { view: view, settings: vgSettings.app }); </code></pre>
