Hide Mouse Cursor when it's within HTML5 Canvas Javascript
提问by Chris
I'm in the process of making a game using Javascript and the html5 canvas element as an alternative to Flash. My question is: is there any bit of code I can use to hide the mouse cursor/pointer as it passes within the canvas? Help is much appreciated!

I don't think you need Javascript for this, you can just use CSS. Assign your canvas a div id/class, and then use this in your CSS template:
我认为您不需要为此使用 Javascript，您可以只使用 CSS。为您的画布分配一个 div id/class，然后在您的 CSS 模板中使用它：
* {cursor: none;}
* {cursor: none;}

You can use javascript to manipulate cursor style. Code:
您可以使用 javascript 来操作光标样式。代码：
<div id="canvas_div_no_cursor">
<!-- canvas here -->
</div>
<script type="text/javascript">
document.getElementById('canvas_div_no_cursor').style.cursor = "none";
</script>

The simplest way (on modern browsers) is to set the cursor to noneon the canvas.
最简单的方法（在现代浏览器上）是将光标设置none在画布上。
If your canvas is created in HTML, do:
如果您的画布是用 HTML 创建的，请执行以下操作：
<canvas id="canvas" style="cursor: none;"></canvas>
I would favour this over a style-sheet because you want to guarantee the cursor value is not over-ridden.
我更喜欢这个而不是样式表，因为你想保证光标值不会被覆盖。
If your canvas is created in JavaScript, do:
如果您的画布是用 JavaScript 创建的，请执行以下操作：
const canvas = document.createElement('canvas');
canvas.style.cursor = 'none';
document.body.appendChild(canvas);
