谷歌+1按钮 - 如何添加一个回调？ [英] Google Plus One Button - How to add a callback?

问题描述

我有谷歌+按钮，在我的网站正在呈现如下：

I have the google+ button being rendered on my site as follows:

在JS：

    var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
    po.src = 'https://apis.google.com/js/plusone.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);

在HTML：

<g:plusone size="medium" href="https://site.com"></g:plusone>

我怎么能回调到这个用户点击时检测到？我看到这里的文档：<一href=\"https://developers.google.com/+/plugins/+1button/#jsapi\">https://developers.google.com/+/plugins/+1button/#jsapi没有看到如何与当前的渲染器。谢谢

How can I add a callback to this to detect when the user has clicked? I see the docs here: https://developers.google.com/+/plugins/+1button/#jsapi not seeing how to implement with the current render. Thanks

推荐答案

您可以用回调属性的JavaScript回调添加到您的+1按钮标记。供应驻留在全局命名空间的函数的名称。当用户点击+1按钮它就会被调用。

You can add a JavaScript callback using a callback attribute to your +1 button markup. Supply the name of a function that resides in the global namespace. It will be called when a user clicks on the +1 button.

下面就是你的code可能是这样的：

Here's what your code might look like:

<script>

   function myCallback(jsonParam) {

      alert("URL: " + jsonParam.href + " state: " + jsonParam.state);

   }

</script>

<g:plusone size="medium" href="https://site.com" callback="myCallback"></g:plusone>

您可以了解更多关于在标记这个属性参数的部分文档。

You can learn more about this attribute in the tag parameters section of the documentation.
