    I have two points, lets say x1,y1 and x2,y2. and i have one more point x3,y3, here is the question, i need to check is x3,y3 coordinate occurs in the line between x1,y1 and x2,y2 or not occurs in javascript.


    This is line over Canvas, so i want to detect that there is a line or not ?



    With the help of Equation of Straight Line, you can detect if a point lies on the line or not. Please take a look at this JSFiddle.

    Also, please refer this stackoverflow thread for more info on achieving the same in JavaScript.
