用户点击facebook Like按钮后，我需要运行一个html表单。

 </form>

Answer 1

使用jquery。

$(function () {
    $('.facebookbutton').on('click', function (e) {
        $('.formbuttonclass').click();
    });
});

表单按钮可以隐藏。您也可以使用ID。 ''之间的#id。

https://developers.facebook.com/docs/reference/javascript/FB.Event.subscribe/v2.1

FB.Event.subscribe('edge.create', function (url, html_element) {
    //will get called whenever a user likes or unlikes a like button
    console.log(url);
});
