问题描述
这是HTML和CSS,看起来像这样:
缺少(, )($(window).scrollTop()+ $(window).height()> $(document).height() - 100) at if conditions
$(document).ready(function() {var footer = $('。footer-fix'); $(window).scroll(function(){if(($(window).scrollTop()+ $(window).height()> $ ).height() - 100)&& footer.is(':visible')){footer.stop()。fadeOut(300);} else if(($(window).scrollTop()< $ (document).height() - 100)&& footer.is(':hidden')){footer.stop()。fadeIn(300);}});}); body {height:520px;}。footer-fix {background:rgba(255,255 ,255,0.6);显示:块;位置:固定;底部:0; z-index:999;宽度:100%;填充:12px; border-top:1px solid #fff; box-shadow:0px 0px 10px rgba(0,0,0,.3);}< script src =https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js>< / script>< div类=页脚修复> < p>这是它的内容......< / p>< / div>
I have a contents DIV which is positioned to fixed at bottom of the page.
It's HTML and CSS looks like this:
<div class="footer-fix"> <p>This is its contents......</p> </div> .footer-fix { background: rgba(255,255,255, 0.6); display: block; position: fixed; bottom: 0; z-index: 999; width: 100%; padding: 12px; border-top: 1px solid #fff; box-shadow: 0px 0px 10px rgba(0,0,0,.3); }My question is now I need to hide this fixed bar when page is scrolling down to the bottom or near the bottom of the page.
This is how I tried it in jquery:
$(document).ready(function() { var footer = $('.footer-fix'); $(window).scroll(function() { if($(window).scrollTop() + $(window).height() > $(document).height() - 100) && footer.is(':visible')){ footer.stop().fadeOut(300); } else if($(window).scrollTop() < $(document).height() - 100 && footer.is(':hidden')){ footer.stop().fadeIn(300); } }); });But this is not working for me. Can anybody tell what is the wrong with this.
Hope somebody may help me out. Thank you.
解决方案Missing ( , ) around ($(window).scrollTop() + $(window).height() > $(document).height() - 100) at if conditions
$(document).ready(function() { var footer = $('.footer-fix'); $(window).scroll(function() { if (($(window).scrollTop() + $(window).height() > $(document).height() - 100) && footer.is(':visible')) { footer.stop().fadeOut(300); } else if (($(window).scrollTop() < $(document).height() - 100) && footer.is(':hidden')) { footer.stop().fadeIn(300); } }); });body { height: 520px; } .footer-fix { background: rgba(255, 255, 255, 0.6); display: block; position: fixed; bottom: 0; z-index: 999; width: 100%; padding: 12px; border-top: 1px solid #fff; box-shadow: 0px 0px 10px rgba(0, 0, 0, .3); }<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"> </script> <div class="footer-fix"> <p>This is its contents......</p> </div>这篇关于当页面在jquery中向下滚动时隐藏内容的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
