    IE 10 is so nice.

    But I can't understand Microsoft for IE10.

    Let's see below.

    Use this sample source.

    <!DOCTYPE html>
    <html>
    <body>
    <canvas id="myCanvas" width="300" height="150" style="border:1px solid #d3d3d3;">
    Your browser does not support the HTML5 canvas tag.</canvas>
    <script>
    var c=document.getElementById("myCanvas");
    var ctx=c.getContext("2d");
    ctx.fillStyle = 'rgba(0,0,0,0.4)';
    ctx.fillRect(0,0,998,998);
    ctx.beginPath();
    ctx.arc(100,75,50,0,2*Math.PI);
    ctx.closePath();
    ctx.clip();
    ctx.clearRect(0,0,998,998);
    </script> 
    </body>
    </html>

     

    It doesn't work only on IE 10.

    How about IE 9 ?

    It works great on IE 9.

    What is Microsoft doing about IE 10 ?

    I can't understand.

    Is there anyone knows the solution about this ?

    You can test this at w3schools.com.

    I can't post any url yet.

    Hi,

    use a validator to detect markup errors in your page. validator.w3.org or f12>Validate>HTML

    your page lacks a <head> tag.

    Line 3,        Column 6:     Element head is missing a required instance of child element title.     
    <body>
    see MSDN - arc method for an example of using the canvas arc method.

    This source is from w3schools.com.  Not from me.

    This source works on Firefox, Chrome, Safari, Opera, Ie9.

    Only IE 10 doesn't work.

    Anyway thanks for your answer.

    I'll try to fix it as you said. :)

    Anyway....The problem is not the thing you said.

    Though I fixed 'head' tag error it still doesn't work too.


    IE10 has a problem certainly.

    Thanks. but...

    My problem is not concerned with Markup such as 'title', 'head' but just 'canvas'.

    I'm looking forward to see the patch about this.
