Question

我是新手，我怎么能添加到我的代码scrollTop margin + 100px？在页面上有一些从顶部的边缘，但我找不到他。我无法理解在javascript文件中键入margin-top的位置。

/*************
* = Parallax *
*************/
jQuery(document).ready(function ($) {
    //Cache some variables
    var links = $('.nav').find('li');
    slide = $('.slide');
    button = $('.button');
    mywindow = $(window);
    htmlbody = $('html,body');

    //Create a function that will be passed a slide number and then will scroll to that slide using jquerys animate. The Jquery
    //easing plugin is also used, so we passed in the easing method of 'easeInOutQuint' which is available throught the plugin.
    function goToByScroll(dataslide) {
        var offset_top = ( dataslide == 1 ) ? '0px' : $('.slide[data-slide="' + dataslide + '"]').offset().top;

        htmlbody.stop(false, false).animate({
            scrollTop: offset_top
        }, 1500, 'easeInOutQuart');


    }

    //When the user clicks on the navigation links, get the data-slide attribute value of the link and pass that variable to the goToByScroll function
    links.click(function (e) {
        e.preventDefault();
        dataslide = $(this).attr('data-slide');
        goToByScroll(dataslide);
        $(".nav-collapse").collapse('hide');
    });

    //When the user clicks on the navigation links, get the data-slide attribute value of the link and pass that variable to the goToByScroll function
    $('.navigation-slide').click(function (e) {
        e.preventDefault();
        dataslide = $(this).attr('data-slide');
        goToByScroll(dataslide);
        $(".nav-collapse").collapse('hide');
    });
});

将此内容放入点击事件中，以“滚动到顶部”按钮/链接/其他..

$("body").scrollTop( 100);
