问题描述

I'd like to add a alert message on the page when a user clicks 'g+' button. how can i achieve this ?
here is code :

<g:plusone href="http://test.com//" annotation="inline" width="300"></g:plusone> 
<script type="text/javascript"> 
 (function() { 
    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);
  })();
</script>

推荐答案

只是在您需要一些代码入门的情况下，以下标记将在+1按钮中启用交互事件:

Just incase you want some code to get you started, the following markup will enable the interaction events in a +1 button:

<div
  class="g-plusone"
  data-expandto="bottom"
  data-onendinteraction="onEnded"
  data-onstartinteraction="onStarted"
  data-recommendations="false"
  data-annotation="inline"
  data-height="25"
  data-autoclose="true"
  data-callback="onCallback" 
  data-width="300"
>

以下代码将处理事件:

function onStarted(args){
  console.log("started");
  console.log(args);
}
function onEnded(args){
  console.log("ended");
  console.log(args);
}
function onCallback(args){
  console.log("callback");
  console.log(args);
}

回调将返回按钮的+1状态，开始/结束交互指示用户状态.您可以在此处看到所有事件的演示.

The callback will return the +1 state of the button, start/end interaction indicates the user state. You can see a demo of all the events here.
