/**
 * openwrite 脚本基本逻辑：
 * 函数名和属性名储存在一个数组中(搜索“阅读全文”可定位到)，取值时通过对应的索引取出对应的值。
 * 先构造一个对象(搜索“const .* = function”可定位到)，在下方不远处给它的 prototype 上添加 options 和 init。
 * 点击弹窗中的“提交”按钮时，触发回调(搜索“alert”可定位到)，解析后具体代码如下：

 * function () {
 *     const val = $("#btw-modal-input").val();
 *     if (val === "") {
 *         alert("请输入校验码！");
 *         $("#btw-modal-input").focus();
 *         return;
 *     }
 *     const { blogId } = btw.options
 *     const api = "https://my.openwrite.cn/code/check";
 *     const url = "" + api + "?blogId=" + blogId + "&code=" + val + "";
 *     $.get(url, function (res) {
 *         if (res.result === true) {
 *             localStorage.setItem("TOKEN_" + blogId + "", blogId);
 *             $("#btw-modal-wrap, #read-more-wrap").remove();
 *             $("#" + btw.options.id + "").height("");
 *         } else {
 *             alert("校验码有误！");
 *         }
 *     });
 * }
