CanvasRenderingContext2D .moveTo() method of the Canvas 2D API begins a new sub-path at the point specified by the given (x, y) 坐标。

句法

void ctx.moveTo(x, y);
					

参数

x

The x-axis (horizontal) coordinate of the point.

y

The y-axis (vertical) coordinate of the point.

范例

Creating multiple sub-paths

此范例使用 moveTo() to create two sub-paths within a single path. Both sub-paths are then rendered with a single stroke() 调用。

HTML

<canvas id="canvas"></canvas>
					

JavaScript

The first line begins at (50, 50) and ends at (200, 50). The second line begins at (50, 90) and ends at (280, 120).

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.moveTo(50, 50);   // Begin first sub-path
ctx.lineTo(200, 50);
ctx.moveTo(50, 90);   // Begin second sub-path
ctx.lineTo(280, 120);
ctx.stroke();
