使用jQuery访问画布上的内容

Question

I have very little experience with canvas but I am attempting to access some code written by someone else. I am used to working with the DOM in HTML so I am finding the canvas very unusual.

Their code modifies the canvas and adds two text values. I need to access these two values in my javascript code and read them.

Is this possible? Searching in Google is giving so few answers that I am worried it is not.

Edit: Before anyone asks, the only part I have understood so far is the following:

$("#canvas")[0].getContext('2d');

I am not sure where to go from here. Many thanks

You can use jquery get() method as follows :

var canvas = $("#canvas").get(0);
var twoDContext = canvas.getContext('2d');
