    <p>I am trying to make an image appear to the location of the mouse coordinates when I click the canvas.</p> <p>Right now I have it appearing, but I can only figure out how to do it with automatic updating coordinates and the image will follow the mouse after an "onclick". </p> <p>I need to make it so the image will just move to the location I click, not follow the cursor.</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;style&gt; body { margin: 0px; padding: 0px; } &lt;/style&gt; &lt;/head&gt; &lt;title&gt;Click to make a sad face&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;canvas id="myCanvas" width="2000" height="1000", onClick="makeface();"&gt;&lt;/canvas&gt; &lt;script type="text/javascript"&gt; function writeMessage(canvas, message) { var ctx = canvas.getContext('2d'); ctx.clearRect(0, 0, canvas.width, canvas.height); ctx.font = '18pt Calibri'; ctx.fillStyle = 'black'; ctx.fillText(message, 10, 25); } function getMousePos(canvas, evt) { var rect = canvas.getBoundingClientRect(); return { x: evt.clientX - rect.left, y: evt.clientY - rect.top }; } var canvas = document.getElementById('myCanvas'); var ctx = canvas.getContext('2d'); canvas.addEventListener('mousemove', function(evt) { var mousePos = getMousePos(canvas, evt); var message = 'Click to make a face appear at coordinates: ' + mousePos.x + ',' + mousePos.y; writeMessage(canvas, message); }, false); function makeface() { canvas.addEventListener('mousemove', function(evt) { var mousePos2 = getMousePos(canvas, evt); var headx = mousePos2.x; var heady = mousePos2.y; var message = 'You made the face appear, you are currently at coordinates: ' + mousePos2.x + ',' + mousePos2.y; writeMessage(canvas, message); var headrad = 50; var smileoffsetx=0; var frownoffsety = 33; var smilerad=20; var eyeoffsety = -10; var lefteyeoffsetx = -15; var righteyeoffsetx = -lefteyeoffsetx; var eyerad = 8; ctx.strokeStyle="blue"; ctx.lineWidth = 5; ctx.beginPath(); ctx.arc(headx,heady,headrad,0,2*Math.PI,true); ctx.closePath(); ctx.stroke(); ctx.beginPath() ctx.arc(headx+smileoffsetx,heady+frownoffsety,smilerad,-.20*Math.PI,-.80*Math.PI,true); ctx.stroke(); ctx.beginPath() ctx.arc(headx+lefteyeoffsetx,heady+eyeoffsety,eyerad,0,2*Math.PI,true); ctx.fillStyle="blue"; ctx.fill(); ctx.beginPath() ctx.arc(headx+righteyeoffsetx,heady+eyeoffsety,eyerad,0,2*Math.PI,true); ctx.fill(); }, false); } &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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.
