我有一个问题要问, 希望能得到答案 。 我正制作一个有四个 < codeanchor points " pages. divs 有100%的高度, 以填满整个浏览器的高度 。 我的头( logo 和 导航) 有固定的位置 。 当用户点击链接或滚动到第三和第四个 < codeanchor 点时, 我想改变我的头的风格( 我的标识和链接颜色 ) 。 有人能帮助我解决这个问题吗?
< a href=> "http://imakewebthings.com/jquery-waypoints" rel="no follow" >jQuery Waypoints 可能是一个容易实现这一点的方法。它允许您在用户滚动超过页面上某些点时触发任何动作 。
这将检查页面上的 div 相对于您在滚动中瞄准的 div 的高度位置。 我相信这就是您正在寻找的 。
$(function(){
$(window).scroll(function(){
if($( #targetDiv ).offset().top >= window.scrollX ){
}
})
})
