The HTMLCanvasElement.height
property is a positive integer
reflecting the height
HTML attribute of the <canvas>
element interpreted in CSS pixels. When the attribute is not specified, or if it is set to an invalid value, like a negative, the default value of 150
is used.
This is one of the two properties, the other being HTMLCanvasElement.width
, that controls the size of the canvas.
Syntax
var pxl = canvas.height; canvas.height = pxl;
Examples
Given this <canvas>
element:
<canvas id="canvas" width="300" height="300"></canvas>
You can get the height of the canvas with the following code:
var canvas = document.getElementById('canvas'); console.log(canvas.height); // 300
