从画布中删除可点击事件

Question

有人可以帮我删除可点击的事件并使此脚本成为默认行吗？我的意思是每当我访问该页面时，该行应该已经绘制。我只是想摆脱点击。

$(function(){
    $('body').on('click', '#stage .cell', function(e){
   if(!$(this).is('.clicked'))
        {
            $(this).addClass('clicked');

            var last_clicked = $($('.cell.last_clicked').get(0));
            if($('#stage .clicked').length > 1){

                add_line(
                        $(this).position().left + ($(this).outerWidth(true)/2),
                        $(this).position().top + ($(this).outerHeight(true)/2),
                        last_clicked.position().left + (last_clicked.outerWidth(true)/2), 
                        last_clicked.position().top + (last_clicked.outerHeight(true)/2)
                        );
            }

            $('#stage .cell').removeClass('last_clicked');

            $(this).addClass('last_clicked');
        }                
    });

    var ctx = document.getElementById("background").getContext("2d");
    var lines = [];

    function draw_loop()

        ctx.fillStyle="#fff";
        //Clear the background
        ctx.fillRect(0,0,7000,7000);

        for(var i in lines)

            ctx.beginPath();
            ctx.lineWidth = Math.floor((1+Math.random() * 10));
            ctx.strokeStyle = lines[i].color;
            ctx.moveTo(lines[i].start.x, lines[i].start.y);

            ctx.stroke();
        }        
        setTimeout(draw_loop, 25/1000);
         console.log(lines);
    }
    //Run the draw_loop for the first time. It will call itself 25 times per second after that    
    draw_loop();

    //Adds a line in the drawing loop of the background canvas
    function add_line(start_x, start_y, end_x, end_y, color)
    {
        lines.push({
            start:{
                x: start_x,
                y: start_y

            end:{
                x: end_x,

            'color': color?color:"#"+("000"+(Math.random()*(1<<24)|0).toString(16)).substr(-6)
        });
    }
