Set the canvas size using CSS or the HTML width/height attributes to be, for example, 200 x 400:

使用CSS或HTML width / height属性将画布大小设置为例如200 x 400：

and make sure you also set the width/height properties of the canvas object in the JavaScript, to avoid the text to render blurry, for example:

并确保还设置JavaScript中canvas对象的width / height属性，以避免文本呈现模糊，例如：

canvas.width = 1800canvas.height = 1200

First thing, get a reference to a canvas

首先，获取对画布的引用

const canvas = document.querySelector('canvas')

and create a context object from it:

并从中创建一个上下文对象：

const context = canvas.getContext('2d')

Now we can call the fillText() method of the context object:

现在我们可以调用上下文对象的fillText()方法：

context.fillText('hi!', 100, 100)

Make sure the x and y coordinates of the starting point are included in the canvas size.

确保起点的x和y坐标包含在画布尺寸中。

You can pass additional properties before calling fillText() to customize the appearance, for example:

您可以在调用fillText()来自定义外观之前传递其他属性，例如：

context.font = 'bold 70pt Menlo'context.fillStyle = '#ccc'context.fillText('hi!', 100, 100)
