这是我的代码,用于重置用户的密码,以防用户忘记密码.数据通过AJAX请求发送到PHP代码,PHP代码根据输入的有效性简单地回显“Y”或“N”.
问题是,AJAX调用在Firefox 19和IE 9中不起作用.我没有在其他版本的IE中尝试过. AJAX调用在chrome和safari中完美运行.有没有人遇到同样的问题？有人可以帮忙吗？

解决方法
您必须为事件处理程序的参数使用事件对象,chrome和safari在触发事件但firefox没有时会有一个名为event的全局事件对象.所以event.preventDefault();会导致错误.
例如.
$('#email_send').click(function(event) {
