无法执行GM_xmlhttprequest。 get请求未生成

Question

我已经找到了一个从DOM收集数据的scipt，并且点击按钮应该将数据发送到php脚本。 GM_xmlhttprequest方法在检查firebug时没有生成任何get请求。

我们还可以在greasemonkey中使用jQuery.ajax吗？ （无法使其工作）

以下是代码：

                    // ==UserScript==
                    // @name        anna
                    // @namespace   *
                    // @description Script to send the data to a server during case closure
                    // @include     https://172.22.32.100/yii_entry.php?r=loader/load/url/case_detail.php3?ticket_num*
