    javascript - How to know if raphael object is hidden? - Stack Overflow

    programmeradmin3浏览0评论

    I am creating a diagram application in which I hide and show few elements e.g.

    var c = paper.circle(10, 10, 10);
c.hide()

var c2 = paper.circle(10, 10, 10);
c2.show()

    Now I want to act upon such shapes e.g. calculate bounding box etc but I am not able to find how to get if shape is hidden or not? Is there something like this shape.is_visible() or shape.attr('visible')

    • 1 this really ought to be in the raphael api, can't believe we have to implement it ourselves – chrismarx Commented Jun 4, 2013 at 15:42

    Reset to default 17

    I took a look at the documentation and source code and cooked this up (untested):

    Raphael.el.is_visible = function() {
    return (this.node.style.display !== "none");
}

    Call as follows:

    var c = paper.circle(10, 10, 10);
c.hide();
if (c.is_visible())
    alert("Visible");
else
    alert("Invisible");
