Question

我有一個問題，使我的歡迎欄固定，而滾動通過 my blog。我想在滾動過程中將該AddThis條固定在頂部邊緣。這是代碼：

<script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid=ra-510063517c175536"></script> 
<script type='text/javascript'> 
addthis.bar.initialize({'default':{ 
    "backgroundColor": "#EDEDED", 
    "buttonColor": "#3CA8FA", 
    "textColor": "#FFA733", 
    "buttonTextColor": "#FAFAFA" 
},rules:[ 
    { 
     "name": "AnyOther", 
     "message": "If you enjoy this page, do me a favor:", 
     "action": { 
      "type": "button", 
      "text": "Share this page", 
      "verb": "share", 
      "service": "preferred" 
     } 
    }, 
    { 
     "name": "Twitter", 
     "match": { 
      "referringService": "twitter" 
     }, 
     "message": "If you find this page helpful:", 
     "action": { 
      "type": "button", 
      "text": "Tweet it!", 
      "verb": "share", 
      "service": "twitter" 
     } 
    }, 
    { 
     "name": "Facebook", 
     "match": { 
      "referringService": "facebook" 
    }, 
    "message": "Tell your friends about me:", 
    "action": { 
     "type": "button", 
     "text": "Share on Facebook", 
     "verb": "share", 
     "service": "facebook" 
    } 
}, 
{ 
    "name": "Google", 
    "match": { 
     "referrer": "google.com" 
    }, 
    "message": "If you like my blog, let Google know:", 
    "action": { 
     "type": "button", 
     "text": "+1", 
     "verb": "share", 
     "service": "google_plusone_share" 
     } 
    } 
]}); 
</script> 

有一個名爲showOnScrollTo參數（你可以找到關於它here的解釋），但我不知道如何或在哪裏使用它。我試着把CSS放在「位置：固定的」在這個代碼的幾個地方，但它沒有工作。如果有人有想法，請幫忙。在此先感謝

要固定你可以指定參數「固定」，並將其設置爲true頁的頂部欄，所以總是使杆固定的一個例子是：

<script type='text/javascript'> 
    addthis.bar.initialize({'default':{ 
     fixed: true, 
     showOnScrollTo: [element | string | integer | float] 
     }); 
</script> 

並且在「默認」對象內，您也可以指定「showOnScrollTo」參數。
