Length of Quadratic Curve

Question

I have a Bezier Curve on an HTML5 Canvas and need to figure out the length of the curve. How can I do this easy?

Lets say :

var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
context.beginPath();
context.moveTo(188, 130);
context.bezierCurveTo(140, 10, 388, 10, 388, 170);
context.lineWidth = 10;

How can I figure out the length of the curve I have created?

You make what "easier"? There is absolutely no code in your question that shows "not-so-easy" way of achieving whatever you want. — Alexei Levenkov, Apr 09 '13 at 04:43

You'll have to find it mathematically, using the parameters you pushed in.

Use this reference: Calculate the length of a segment of a quadratic bezier
