Allowing offset to defined as a function about jquery.scrollto HOT 7 CLOSED

Will check this out asap.

from jquery.scrollto.

One question, are you using "vainilla" scrollTo or serialScroll/localScroll on top?
Considering you call the plugin each time you need to scroll, you can basically define what's the offset before each call by customizing the options object.
If you are using those plugins, you can change the value within the onBefore callback.
Wouldn't that be enough?

@flesler dynamic offset would be very useful for responsive layouts, for example in twitter bootstrap Hero template, the fixed navbar has 47px. So I need to offset all my localscrolls by 47. But if the viewport is smaller than 980px then responsive bootstrap styles change navbars position from "fixed" to "static"... and then the offset is no longer needed.

In this case it would be great if we could do:

$('.navbar').localScroll({
    duration: 800,
    offset:   { 
        top: function(){ return ($('.navbar').css('position') == 'static') ? 0 : -47 }
    }
});

from jquery.scrollto.

For future reference:

• following @flesler 's post this code did the trick:

$('.navbar').localScroll({
    duration: 800,
    onBefore: function(){
        this.offset = {
            top: ($('.navbar').css('position') == 'static') ? 0 : -47
        };
    }
});

from jquery.scrollto.

I think that's good enough. That's the reason I passed the settings to the
onBefore. What do you think.

@flesler i think onBefore is enough, you might just want to emphersize it in docs - it took me a long while to find out that onBefore is what I needed
