<script> <br /> var c=document.getElementById("myCanvas"); <br /> var cxt=c.getContext("2d"); <br /> cxt.moveTo(20,20); <br /> cxt.lineTo(150,50); <br /> cxt.lineTo(2o,50); <br /> cxt.stroke(); <br /> </script>
代码如上,但是运行时只有一个矩形框,框内没有画的这两条线,怎么回事?
回复讨论(解决方案)
1. <script>写错了 javascript 是i不是o <br /> <br />2. cxt.lineTo(2o,50); 是0不是“O” </script>
仔细检查下你敲的代码
