Canvas学习-1
简单示例
<!DOCTYPE html> <html> <head> <style> body{ background: #dddddd; } #canvas{ margin:10px; padding:10px; background: #ffffff; } </style> </head> <body> <canvas id='canvas' width='600' height='300'> Canvas not supported </canvas> <script type="text/javascript"> var canvas =document.getElementById('canvas'); context=canvas.getContext('2d'); context.font='38pt Arial'; context.fillStyle='cornflowerblue'; context.strokeStyle='blue'; context.fillText('Hello Valentine',canvas.width/2-150,canvas.height/2+15); context.fillStroke('Hello Valentine',canvas.width/2-150,canvas.height/2+15); </script> </body> <footer></footer> </html>
注意:canvas默认大小为300*150像素
注意:实用width与height而非css设置canvas的大小
