单击类似按钮时显示消息？ [英] show message when like button is clicked?

问题描述

我使用以下代码在用户点击facebook like按钮时提醒用户。它仅在Opera浏览器上提醒用户。如何解决此问题并使其适用于所有浏览器？

I am using the following code to alert the user when he click the facebook like button. It is alerting the user only on Opera browser. How do I fix this problem and make it work with all browsers ?

<script>
FB.Event.subscribe('edge.create',
    function(response) {
        alert("You liked the URL");
    }
);
</script>

我也可以使用Jquery。

推荐答案

你把这段代码放在哪里了？

Where did you put this code ?

对我来说，你必须把它放在init中，如下所示： / p>

For me you have to put this in the init like this :

window.fbAsyncInit = function() {
    FB.init({
      appId  : APP_ID,
      status : true, 
      cookie : true, 
      xfbml  : true 
    });

    FB.Event.subscribe('edge.create',
        function(response) {
            alert("You liked the URL");
        }
    );    
};

如果你已经调用了FB.init，你必须使用这样的技巧：

If you have already call the FB.init, you have to use a trick like this :

<script type="text/javascript">
    function hasFBLoad(){
        if(FB != 'undefined'){
            FB.Event.subscribe('edge.create',
                function(response) {
                    alert("You liked the URL");
                }
            );
        }else{
            setTimeout('hasFBLoad()', 200);
        }
    }
    hasFBLoad();
</script>
