我在我的网站上使用粘性。它在 CSS 上完美配置,但是当我开始滚动时,它会转到左侧。我希望它粘在它所在的右侧。我怎样才能做到这一点?
我确定它是 JS 文件的一部分
(function($){
$.fn.extend({
//plugin name - jsticky
jsticky: function(options) {
//Settings list and the default values
var defaults = {
marginTop: 0
};
var options = $.extend(defaults, options);
return this.each(function() {
var o = options;
//Assign current element to variable, in this case is UL element
var obj = $(this);
var offset = obj.offset();
var topOffset = offset.top;
var marginTop = obj.css("marginTop");
var marginTopNum = parseInt(marginTop);
var diff = topOffset - marginTopNum;
var offset = obj.offset();
var topOffset = offset.top;
var leftOffset = offset.left;
var marginTop = obj.css("marginTop");
var marginLeft = obj.css("marginLeft");
$(window).scroll(function() {
var WindowScrollTop = $(window).scrollTop();
var scrollTop = WindowScrollTop + o.marginTop;
if (scrollTop >= topOffset){
obj.css({
marginTop: o.marginTop,
marginLeft: leftOffset,
position: 'fixed'
});
}
if (scrollTop < topOffset){
obj.css({
marginTop: marginTop,
marginLeft: marginLeft,
position: 'fixed'
});
}
});
});
}
});
})(jQuery);
