The CanvasRenderingContext2D.lineTo() method of the Canvas 2D API connects the last point in the sub-path to the x, y coordinates with a straight line (but does not actually draw it).

Syntax

void ctx.lineTo(x, y);

Parameters

x
The x axis of the coordinate for the end of the line.
y
The y axis of the coordinate for the end of the line.

Examples

Using the lineTo method

This is just a simple code snippet which uses the lineTo method. Use the beginPath() to begin a path to draw a line on, move the pen with moveTo() and use the stroke() method to actually draw the line.

HTML

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

JavaScript

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.moveTo(50, 50);
ctx.lineTo(100, 100);
ctx.stroke();

Edit the code below and see your changes update live in the canvas:

Playable code
<canvas id="canvas" width="400" height="200" class="playable-canvas"></canvas>
<div class="playable-buttons">
  <input id="edit" type="button" value="Edit" />
  <input id="reset" type="button" value="Reset" />
</div>
<textarea id="code" class="playable-code">
ctx.beginPath();
ctx.moveTo(50,50);
ctx.lineTo(100, 100);
ctx.stroke();</textarea>
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;

function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);
  eval(textarea.value);
}

reset.addEventListener("click", function() {
  textarea.value = code;
  drawCanvas();
});

edit.addEventListener("click", function() {
  textarea.focus();
})

textarea.addEventListener("input", drawCanvas);
window.addEventListener("load", drawCanvas);
