快速喜欢Tumblr上的按钮

Question

任何人都可以解释一下这个page中的按钮是如何工作的吗？

正如你所看到的，一旦整个页面加载完成，悬停在文章或图片上会显示一些按钮，包括一个像按钮（心脏形状在左下角）。

任何人都可以解释它是如何工作的？我一直试图找出一段时间，尝试在源代码上的脚本，但无济于事。

Answer 1

这是我在源代码中发现的，这意味着div的链接像按钮和reblog按钮只是硬编码和隐藏与CSS。正如你所看到的，当你将鼠标悬停在元素上时，会有一个css块。所以它只是CSS。

编辑： 我加了一个帖子的HTML代码，你可以看到有一对夫妇的div与类永久

CSS代码

/* CLAW */ 
    .claw .permalink {height: 60px; width: 60px; margin-bottom: -60px; position:  relative; background-repeat: no-repeat; background-position: -31px -31px; 
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=60)"; 
filter: alpha(opacity=60); 
-moz-opacity: 0.6; 
-khtml-opacity: 0.6; 
opacity: 0.6; 
} 
.claw .permalink:hover { 
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=85)"; 
filter: alpha(opacity=85); 
-moz-opacity: 0.85; 
-khtml-opacity: 0.85; 
opacity: 0.85; 
} 
.claw.permalink {display: none;} 
.claw .claw.permalink {display: block!important;} 
    .post-shell.claw:hover .perma-link {background-position: 0px 0px;} 
    .post-shell.claw:hover .perma-source {background-position: -62px 0px;} 
    .post-shell.claw:hover .perma-like {background-position: 0px -62px;} 
    .post-shell.claw:hover .perma-reblog {background-position: -62px -62px;} 
    .claw .perma-link {margin-left: 12px;} 
    .claw .perma-source {margin-right: 12px; float: right;} 
    .claw .perma-reblog {margin: -60px 0 0 0; float: right;} 
    .claw .perma-like {margin: -60px 0 0 0;} 

HTML代码一个职位的：

<div class="post-shell claw"> 
    <a href="http://cicerontheme.tumblr.com/post/7703094650" title="posted 5 months ago with 178 notes"><div class="permalink claw perma-link"></div></a> 
    <a href="http://amarisha.tumblr.com/post/5376110038" title="reblogged from amarisha"><div class="permalink claw perma-source"></div></a> 

    <div class="post photo" id="7703094650" rel="http://www.tumblr.com/reblog/7703094650/vNQMTLwX"> 
     <a href="http://www.tumblr.com/photo/1280/7703094650/1/tumblr_ll09emcfFn1qaywzm"><img src="http://27.media.tumblr.com/tumblr_ll09emcfFn1qaywzmo1_400.jpg" alt="" width="400" border="0" /></a> 
     <a href="http://cicerontheme.tumblr.com/post/7703094650" class="like-link" title="like this post"><div class="permalink perma-like"></div></a> 
     <a href="http://www.tumblr.com/reblog/7703094650/vNQMTLwX" title="reblog this post"> 
    <div class="permalink perma-reblog"></div></a> 
    </div>  
</div> 

Answer 2

我写这个的tumblr教程：http://like-button.tumblr.com

一个就好保存到服务器，可以使用下面的URL，并将其设置为src属性的无形的：

http://www.tumblr.com/<command>/<oauthId>?id=<postId> 

• 命令：like或unlike
• oauthId：最后八个字{ReblogURL}
• 帖子ID：{PostID}

示例：

http://www.tumblr.com/like/23err8u4?id=844392923 

在</head>之前立即将以下代码块剪切并粘贴到您的主题中。这会在每个帖子上给你一个类似于默认Tumblr灰色心脏的按钮。当你将鼠标悬停在它上面并点击它时，它会变成红色。如果再次点击它，它会再次变成灰色并删除Like。

<style> 
.my-like { 
    background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABMAAAARCAYAAAA/mJfHAAABH0lEQVQ4y62T30vCUBiGv/9YuhBLkCA08FdogRFFYFEUhhZNCCQoSESiIOii68pl5qV6s8Eb7+SMHXNs6S7ejZ3zvA+ccT4BICofvS88dJ7w8vqG8WQC754K17lPjrx3z3l8D4YoVaqIrWbcJNbzaHefNZjfXPdy5b0jsO/IRqMxUpmSBnhz2bx1QL79GPbpEePmzhdSyW8fBDL0SK68HwiGCT2S3NiKREaPzP7QRRNPZSHpwm4kMnqkYbQikdEjZv8HK2ubS4nY75mD6WU8qzeXkrHvToBlWSjuHC4kYo99V8bwBnM0/iMiz542myq2bSPskcmR/zPos7lvP8Lv/nGd+/N6c2Xq2KcXhiY6qV1rxwotU3n/NHF8fgW+g9hfsHJlJUYljcgAAAAASUVORK5CYII=) !important; 
    height:17px; 
    width:19px; 
    cursor:pointer; 
    display:inline-block; 
    vertical-align:top; 
} 
.my-liked, .my-like:hover { 
    background-image: url(data:image/png;base64,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) !important; 
    height:17px; 
    width:19px; 
    cursor:pointer; 
    display:inline-block; 
    vertical-align:top; 
} 
</style> 
<script> 
window.onload = function() { 
document.body.insertAdjacentHTML('beforeEnd', '<iframe id="my-like-frame" style="display:none;"></iframe>'); 
document.addEventListener('click', function (event) { 
    var myLikeLink = event.target; 
    if(myLikeLink.className.indexOf('my-like') > -1) { 
     var myLikeFrame = document.getElementById('my-like-frame'), 
      liked = (myLikeLink.className == 'my-liked'), 
      command = liked ? 'unlike' : 'like', 
      reblog = myLikeLink.getAttribute('data-reblog'), 
      postId = myLikeLink.getAttribute('data-id'), 
      oauth = reblog.slice(-8), 
      likeUrl = 'http://www.tumblr.com/' + command + '/' + oauth + '?id=' + postId; 
     myLikeFrame.src = likeUrl; 
     liked ? myLikeLink.className = 'my-like' 
      : myLikeLink.className = 'my-liked'; 
    }; 
}, false); 
}; 
</script> 

然后剪切并粘贴以下按钮代码到你的主题，你希望你的喜欢按钮是（这一定是你的{block:Posts}块内）。

代码：

<div class="my-like" data-reblog="{ReblogURL}" data-id="{PostID}"></div>
