    <p>I'd like to find a better way to output console messages to an HTML page. This method seems to be pretty slow.</p> <pre><code>&lt;html&gt; &lt;title&gt;Logging test&lt;/title&gt; &lt;head&gt; &lt;SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"&gt; &lt;!-- function log(s) { if(!log.start) { var date = new Date(); log.count = 0; _log("0", "log() started at " + date); log.start = date.valueOf(); } _log(new Date().valueOf() - log.start, s); } function _log(header, s) { var logMessages = document.getElementById("logMessages"); if(!logMessages) { alert(logMessages); return; } var message = document.createElement("div"); message.className = "logMessage"; var content = ""; content += "&lt;span class=\"time\"&gt;" + header + "&lt;/span&gt;"; content += "&lt;span class=\"line\"&gt;" + (log.count++) + "&lt;/span&gt;"; content += "&lt;span class=\"level\"&gt;" + "" + "&lt;/span&gt;"; content += "&lt;span class=\"msg\"&gt;" + s.replace(/ /g, "&amp;nbsp;").replace(/\n/g, "&lt;BR /&gt;") + "&lt;/span&gt;"; message.innerHTML = content; logMessages.appendChild(message); setTimeout(function(){message.scrollIntoView(true)},1); } function main(e) { if(window.confirm("Would you like to display logging?")) { for(var i=0;i&lt;5000;i++) { log("Hello World " + i); } } } //--&gt; &lt;/SCRIPT&gt; &lt;style&gt; .logMessage { border-bottom: 1px black solid; font-size: 8pt; font-family: Lucida Console; } .logMessage .line, .logMessage .time { width: 30px; } .logMessage .level { display: none; } .logMessage .msg { } #logMessages { overflow: auto; } &lt;/style&gt; &lt;/head&gt; &lt;body onload="main()"&gt; &lt;div id="logMessages"&gt;&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COSpeed seems fine to me, though the scroll might be causing some issues with lots of logs happening quickly. Only issue I see is that in FF the rendering of log messages dies after about 2300 (just shows blank after that), though IE and chrome render it fine.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
