单击按钮时JavaScript不起作用

Question

我刚为我的电子邮件检查程序编写了一些JavaScript。单击按钮时将检查textarea的每一行，但当我将邮件列表放在textarea中时，它不起作用。

单击该按钮时，它会将邮件列表的每一行发送到sys_api.php?email=，但没有PHP错误。

有人可以帮助我吗？

        function sys_brain(list, mlist) {
        list = $('#mailist').val();
        list = list.split('\n');

            ajaxCall = $.ajax ({
                type:"Get",
                email: mlist,
                url: "sys_api.php?email=" + mlist,
                async: true,
                beforeSend: function(sys_loading) {
