Question

all anchor in my page have different offset value and position tip: I user masonry effect but does not work correctly

function scrollToAnchor(aid) {
    var aTag = $("a[id='" + aid + "']");
    $('html,body').animate({ scrollTop: aTag.position().top  }, 'slow');
}

Answer 1

You should use offset instead of position().

But I know by experience that Masonry by default doesn't use position absolute & top, left but it uses a css3-transform instead. And this means that .left and .top will output 0 instead of the css3-transform-value.
