Question

I\'m trying to build a jQuery plugin that allows you to drag and draw a rectangle (or a div with a border) but I\'m not sure how to do it. I don\'t know of any that currently ha

$("#YOUR_ELEMENT_ID").on("mousedown", function (e) {
    var click_x = e.pageX;
    var click_y = e.pageY;

    /* Posição do objeto */
    var x = parseFloat($(this).css("left").replace("px", "")),
        y = parseFloat($(this).css("top").replace("px", ""));
    /* Calcula distância no eixo x */
    var distanc_x = Math.abs(x - click_x);
    var distanc_y = Math.abs(y - click_y);

    $("#YOUR_ELEMENT_ID")
        .on("mousemove", function (e) {

            var new_x = e.pageX - distanc_x;
            var new_y = e.pageY - distanc_y;

            $(this).css({
                top: new_y,
                left: new_x,
            });

        }).on("mouseup", function (e) {
        $(this).off("mousemove");
    });

});
