我正在使用此测试页：http://www.comehike.com/test_fb_connect.php
当用户使用facebook登录时，系统应该调用ajax脚本。它发生在使用Chrome时，而不是Firefox。
以下是该页面的代码：

您正在尝试调用跨域ajax请求。但由于same origin policy，它被多个浏览器阻止了。为了解决这个问题，您可以关注these steps。
答案 1 :(得分：0)
我找到了答案。
我以前有这个：
request.open("GET", url , true);
但是firefox喜欢这样：
request.open("GET", url , false);
我想知道整个网站的含义是什么。有人知道吗？
