我想了两种不同的方法来解决这个问题,但我需要帮助.
I thought of 2 different methods to approaching this, but I need assistance.
我该怎么做?
我目前正在使用 stickyjs.
但我没有看到执行我所要求的功能.
But I don't see a feature for doing what I asked.
demo - http://jsfiddle.net/m6q6j8xL/3/
这是自定义js
在这个演示中,标题变为绿色(fixed
),当你到达蓝色时,div
变回normal
,当你是从蓝色 div 出来,它变回 fixed
in this demo the header changes to green(fixed
) and when you reach to blue div
changes back to normal
and when u are out from the blue div it changes back to fixed
将填充添加到 div 以便在更改为固定时不会影响窗口滚动
padding is added to div so that it doesn't effect window scroll when changed to fixed
var stickyNavTop = $('.header').offset().top;
function scrolling() {
doc = $(document).height()
hidingtop = $('.hiding').offset().top;
hidingbottom = $('.hiding').position().top + $('.hiding').outerHeight(true) // finding the outer height
if ($(window).scrollTop() > hidingtop && $(window).scrollTop() < hidingbottom) {
$('.header').removeClass('sticky');
$('.container').css('padding-top', '0');
}
}
var stickyNav = function () {
var scrollTop = $(window).scrollTop();
if (scrollTop > stickyNavTop) {
$('.header').addClass('sticky');
$('.container').css('padding-top', '100px');
} else {
$('.header').removeClass('sticky');
$('.container').css('padding-top', '0');
}
};
stickyNav();
$(window).scroll(function () {
stickyNav();
scrolling()
});
