Html5 canvas Problems
The reason is that your browser card and image are not read. Wait a while, or use the code I wrote.
<! Doctype html>
<Html>
<Body>
<Head>
<Canvas id = "myCanvas" width = "200" height = "100" style = "border: 1px solid # c3c3c3;">
Your browser does not support the canvas element.
</Canvas>
<Script type = "text/javascript">
Window. onload = function (){
Var c = document. getElementById ("myCanvas ");
Var cxt = c. getContext ("2d ");
Var img = new Image ();
Img. src = "www.w3school.com.cn/ I /eg_flower.png ";
Cxt. drawImage (img, 0, 0 );
