    <p>I am trying to learn HTML5 Canvas, which drawn from javascript codes.</p> <p>It seems that I could not separate Javascript code from the original html. had been looking some solutions:</p> <ul> <li><a href="https://stackoverflow.com/questions/11349613/html5-canvas-not-working-in-external-javascript-file">HTML5 Canvas not working in external JavaScript file</a></li> <li><a href="https://stackoverflow.com/questions/11032138/canvas-html-tag">canvas html tag</a></li> </ul> <p>These has not been a solution for me, as after I implement both solutions what appears to me is blank canvas.</p> <p>Here is my code.</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;Christoper Hans' Paint HTML5 Project&lt;/title&gt; &lt;link rel="stylesheet" type="text/css" href="paint.css"&gt; &lt;script type="text/javascript"&gt;&lt;!-- window.addEventListener('load', function () { var ctx = document.getElementById("paint").getContext("2d"); ctx.canvas.width = window.innerWidth; ctx.canvas.height = window.innerHeight; function drawRect(ctx, x1, y1, x2, y2, fill) { ctx.fillStyle=fill; ctx.fillRect(x1, y1, x2, y2); } drawRect(ctx, 100, 100, 200, 250, "FF0000"); }, false); // --&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;canvas id="paint" width="500" height="500" style="border:1px solid #c3c3c3;"&gt; Your browser does not support the HTML5 canvas tag. &lt;/canvas&gt; &lt;/body&gt; </code></pre> <p></p> <p>I don't know why but only this kind of code <em>which I got from a post from this website</em> works and I could not separate the javascript to external file.</p> <p>TL;DR : Wanted to separate javascript from html to work with canvas.</p> <p>Any help guys?</p>

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).
