製作一個導航欄用戶滾動時粘住

Question

我有兩個導航欄。讓我們說一個頂部的用戶導航欄和用戶導航欄下的主要導航欄。

我想在用戶滾動時有一個粘滯的主導航欄。

究竟即時試圖做的是使導航欄相似，我最喜歡的遊戲網站標題，這裏https://playoverwatch.com/en-us/ 見當您滾動和頂部第二個堅持是如何在第一導航欄很好消失？我真的想要有類似的東西，或者完全像這樣。

#ipsLayout_header header { 
 
    margin-bottom: 15px; 
 
    background-color: rgba(2,25,72,.3); 
 
} 
 
.ipsLayout_container { 
 
    max-width: 1340px; 
 
    padding: 0 15px; 
 
} 
 
.ipsNavBar_primary { 
 
    background: #304d66; 
 
}

<div id="ipsLayout_header"> 
 
    <header> 
 
     <div class="ipsLayout_container"><!-- my first navbar --> 
 
      <ul id="elUserNav"> 
 
       <li id="cCreate"> 
 
\t \t \t \t links 
 
       </li> 
 
      </ul> 
 
     </div> 
 
    </header> \t 
 
    <nav class="ipsLayout_container"><!-- my second navbar --> 
 
     <div class="ipsNavBar_primary"> 
 
      <ul class="ipsResponsive_block"> 
 
       <li id="elNavSecondary_34"> 
 
       links 
 
       </li> \t 
 
      </ul> 
 
     </div> 
 
    </nav> 
 
</div>

Answer 1

這裏是代碼。使標題div固定在頂部並在滾動時給頂部減去上部菜單高度。

CSS -

#ipsLayout_header{ 
    position: fixed; 
    top: 0; 
    left: 0; 
    width: 100%; 
    display: block; 
    z-index: 10; 
    background: #fff; 
    -webkit-transition: .3s all 0s ease; 
    -moz-transition: .3s all 0s ease; 
    transition: .3s all 0s ease; 
} 

js-

$(window).scroll(function() { 
    var scroll = $(window).scrollTop(); 
    var headerHeight = $('header').outerHeight(); 
    if (scroll >= 100) { 
    $("#ipsLayout_header").css('top', -headerHeight); 
    } 
    else { 
    $("#ipsLayout_header").css('top', '0'); 
    } 
});

嘗試......

$(document).ready(function(){ 
 
\t $(window).scroll(function(){ 
 
    \t if ($(document).scrollTop()>$('nav').offset().top) 
 
    \t $('nav').addClass('onTop'); 
 
    else 
 
    \t $('nav').removeClass('onTop'); 
 
    }) 
 
})

#ipsLayout_header{ 
 
    width:100%; 
 
    height:800px; 
 
    background:#feacbe; 
 
    padding:0px; 
 
    margin:0px; 
 
    } 
 
    #ipsLayout_header header { 
 
     margin-bottom: 15px; 
 
     height: 44px; 
 
     background-color: rgba(2,25,72,.3); 
 
    } 
 
    .ipsLayout_container { 
 
     max-width: 1340px; 
 
     padding: 0 15px; 
 
    } 
 
    .ipsNavBar_primary { 
 
     width:100%; 
 
     height:40px; 
 
     background: #304d66; 
 
    } 
 
    .onTop{ 
 
     position:fixed; 
 
     z-index:9999; 
 
     width:92%; 
 
     top:0; 
 
    } 
 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> 
 
<div id="ipsLayout_header"> 
 

 
\t <header> 
 
\t \t <div class="ipsLayout_container"><!-- my first navbar --> 
 
\t   <ul id="elUserNav"> 
 
\t \t \t  <li id="cCreate"> 
 
\t \t \t \t links 
 
\t \t \t  </li> 
 
\t   </ul> 
 
\t  </div> 
 
\t </header> 
 
\t 
 
\t <nav class="ipsLayout_container"><!-- my second navbar --> 
 
\t \t <div class="ipsNavBar_primary"> 
 
\t \t \t <ul class="ipsResponsive_block"> 
 
\t \t   <li id="elNavSecondary_34"> 
 
\t \t \t \t links 
 
\t \t   </li> \t 
 
\t \t \t </ul> 
 
\t \t </div> 
 
\t </nav> 
 

 
</div>

的$（document）.scrollTop（）是用來獲取當前的滾動功能窗口的位置，基於你可以改變CSS類。
