Use JavaScript to draw <canvas id = "MyCanvas" width= "height=" style= "brorder:1px" Solid #3c3c3; " ></canvas >

<.script> var C=document.getelement.byid ("MyCanvas"); var Ctx=c.getcontext ("2d");

Ctx.filstyle= "#FF0000"; Ctx.fillrect (0,0,150,75);</script>

10. Use canvas canvas to draw a line <canvas id= "MyCanvas" width= "height=" "style=" border:1px solid #d3dd3d3; ></canvas>

<script> var C=document.getelementbyid ("MyCanvas");

var Ctx=c.getcontext ("2d");

Ctx.moveto (0,0);

Ctx.lineto (500,400);

Ctx.stroke ();</script>

11. Use canvas to draw a circle <canvas id-"" MyCanvas "width=" "height=" "style=" border:1px solid 3d3d3d3; ></canvas>

<script> var C=document.getelementbyid ("MyCanvas");

var Ctx=c.getcontext ("2d");

Ctx.beginpath ();

Ctx.arc (95,50,40,0,2*MATH.PI);

Ctx.stroke ();</script>

12, the use of canvas to draw a solid font <canvas id= "MyCanvas" width= "a" height= "" style= "" broder:1px solid #d3d3d3 "; ></canvas& Gt

The canvas is all the same here no more, draw directly on the canvas as follows:

<scrippt>

var C=document.getelementbyid ("MyCanvas");

var Ctx=c.getcontext ("2d");

var grd=ctx.createlineargradient (0,0,200,0);

Grd.addcolordtorp (0, "red");

Grd.addcolorstop (1, "Black");

CTX.FILSTYLE=GRD; Ctx.fillrect (10,10,150,80);</script> "! --here if the radial gradient only needs to modify the function Ctx.createradialgradienti (0,0,200,1) "

14. Place the image on the canvas

<canvas id= "MyCanvas" width= "" height= "style=" "border:1px solid 3d3d3d3;" ></canvas>

<script> var C=document.getelementbyid ("Mucanvas");
