谷歌 - 如何窥看别人隐藏的 +1


公告 3 Jun 2014: 代码暂时不能使用了， 我懒得去更新 ~
更正 19 Feb 2014: 不适用于中文字当地址名字的目标用户， 我有解决办法，但很懒改... 

我们常常看见网站有 plusone g+1 的按钮:



如果是自己按过 g+1 的话， 你的 Google Plus 帐号图片会出现在旁边， 朋友的话， 也有一定的几率在旁边看见:





 至于那个数目 +3 是推荐在 Google Search 的次数.




分享是另一回事哦， 不影响 g+1 的数目， 不要混淆。你可以分享很多次。




如果是你或你的朋友的话 +1， 会显示在 Google Search 的下面, 不过, 仅限Google Plus 圈子里的朋友。如果是你自己+1，Google Search 会很快更新， 但是朋友的话，更新会花几天不定:




我这篇文章探讨的是 Google Search 的+1， 不是如下图所示的帖子的 +1哦， 不要混淆。




 还有一点，  g+1的按钮不限于别的网站看到的， 因为在 Google Plus 专页也能按 g+1 推荐在 Google Search。 只不过按钮不一样而已。如下图所示， +7047448 按钮。




你的 Google Search +1 过的历史可以在自己专页 的 +1 栏目看见, 当然你也可以看见别人的。




 可是大多数人的隐私设定都是隐藏了 +1  的栏目。




现在我就教你简单的步骤来实现窥看:



步骤 1. 

进入你要窥看的目标专页。比如说如图中的例子，LadyGaga专页。




步骤 2.

 (i) 在那个页面随便一个地方用滑鼠按右键， 选 "Inspect Element"（检查元素）。
(ii) 有些浏览器直接按F12键就可以了。




步骤 3.

 下面会出现新的窗口(你需要用滑鼠把那个窗口拖拉大一点)，你要选 Console。 不同的浏览器(IE, Chrome, Firefox)图形设计都不同， 但都是一样的步骤， 找到 Console 点击就可以了。

Gogole Chrome 浏览器的 Console:




IE 浏览器的Console:



Firefox 浏览器的Console:




步骤 4.

 把下面我写的代码全选，然后copy复制。记得要一字不漏copy, 代码很敏感的,  这个代码很长， 你可能需要scroll。
