The example in this article describes how to use js html5 to draw a simple rectangle on canvas. Share it with everyone for your reference. The specific implementation method is as follows:
<!DOCTYPE html> <html> <body> <canvas id="myCanvas" width="200" height="100" style="border:1px solid #c3c3c3;"> Your browser does not support the HTML5 canvas tag. </canvas> <script type="text/javascript"> var c=document.getElementById("myCanvas"); var ctx=c.getContext("2d"); ctx.fillStyle="#FF0000"; ctx.fillRect(0,0,150,75); </script> </body> </html>
I hope this article will be helpful to everyone’s web programming design.
