Javascript按鈕無法正確加載

我爲我的博客變量定製的Tumblr使用了JS按鈕。該按鈕加載一個彈出式窗口，但不是在每個單獨的帖子下出現，而是全部分組在一起。此外，它的輸出：Javascript按鈕無法正確加載

&quot;

進入Tumblr共享屏幕標題，而不是實際的引號。我怎樣才能點擊彈出窗口的中心？

<script src='http://platform.tumblr.com/v1/share.js'/> 

<span id='tumblr_button_abc123'></span> 
<script type='text/javascript'> 
var strPostUrl = "<data:post.url/>"; 
var strPostTitle = '<data:post.title/>'; 
var tumblr_link_url = strPostUrl.replace("http://",""); 
var tumblr_link_name = strPostTitle.replace(/"/g, '"'); 
</script> 
<script type='text/javascript'> 
var tumblr_button = document.createElement("a"); 
tumblr_button.setAttribute("href", "http://www.tumblr.com/share/link?url=" + encodeURIComponent(tumblr_link_url) + "&name=" + encodeURIComponent(tumblr_link_name)); 
tumblr_button.setAttribute("title", "Share on Tumblr"); 
tumblr_button.setAttribute("style", "display:inline-block; text-indent:-9999px; overflow:hidden; width:81px; height:20px; background:url('http://platform.tumblr.com/v1/share_1.png') top left no-repeat transparent;"); 
tumblr_button.innerHTML = "Share on Tumblr"; 
document.getElementById("tumblr_button_abc123").appendChild(tumblr_button); 
</script>
