Question

有人可以解释一下page中的“按钮”按钮是如何工作的吗？

正如您所看到的，一旦整个页面完成加载，将鼠标悬停在帖子或图片上会显示几个按钮，包括一个类似按钮（左下角的心形状）。

任何人都可以解释一下它的工作原理吗？我一直试图弄清楚它一段时间，在源代码上尝试脚本，但无济于事。

Answer 1

我写了一篇Tumblr教程：http://like-button.tumblr.com

要将Like保存到服务器，请使用以下网址并将其设置为不可见src的{{1}}属性：

<iframe>

命令：http://www.tumblr.com/<command>/<oauthId>?id=<postId>或like
oauthId：unlike
postId：{ReblogURL}

示例：

{PostID}

在http://www.tumblr.com/like/23err8u4?id=844392923之前，将以下代码块剪切并粘贴到您的主题中。这将在每个帖子上给你一个类似按钮，看起来像默认的Tumblr灰色心脏。当您将鼠标悬停在它上面并单击它时，它将变为红色。如果再次单击它，它将再次变为灰色并删除Like。

然后将以下按钮代码剪切并粘贴到主题中您希望类似按钮的位置（这必须位于<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 ?

{block:Posts}

Answer 2

这是我在源代码中找到的，这意味着带有类似按钮和reblog按钮的链接的div只是硬编码并用css隐藏。正如您所看到的，当您将鼠标悬停在元素上时会有一个css块。所以这只是CSS。

编辑：我添加了帖子的HTML代码，你可以看到有几个div与类永久链接

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;}
