Moment timezone data js error: "has no data for <!DOCTYPE html>"

Question

我正在使用设置了 hmvc 功能的 CodeIgniter 3.*。我一直在测试我的应用程序以设置一个使用时区的时钟，该时区使用用户选择的默认时区。这个时钟用的是moment js.

奇怪的是，当我正确设置时钟后，此错误消息会出现在任何未创建 moment 实例的页面上。我不知道为什么会这样。我正在使用 Chrome 来显示我的输出。

我正在使用moment js和moment data cdns:

  <!----moment CDNs ---->

<!----moment timezone CDNs ---->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.13/moment-timezone-with-data-2012-2022.js"></script>

当我不调用 moment 进行初始化时弹出此错误：

我无法弄清楚为什么它只出现在不调用 moment 的页面上。

这是我从你建议的调试中得到的，Adrian Grzywaczewski：

正在调用 get_timezone，因为我在所有页面上都调用了时钟，但此时时区未定义，因此提供了默认时区。获取时区的调用失败这一事实是否改变了什么？

-- 已修改 -- 问题是我的 get_timezone 函数由于某种原因正在返回页面。这是函数的代码：

/**
     * default_time_zone function gets the default time zone to use for the modules.
     * @author Peter Kaufman
     */
    public function default_time_zone() {
        $sql = "SELECT `value` FROM `config` WHERE `name` = 'timezone';";
        $results = $this->db->query($sql)->result();

        if (is_array($results)) {
            $results = (array)array_shift($results);
            $_SESSION['timezone'] = $results['value'];
        } else {
            $_SESSION['timezone'] = 'America/New_York';
        }
    }

    /**
     * get_time_zone gets the timezone to use.
     * @author Peter Kaufman
     */
    public function get_timezone() {
        exit($_SESSION['timezone']);
    }

有些地方还有另一个名为 get_timezone 的函数，因为即使 get_timezone 函数的 link 不正确，也能找到它。

Answer 2

答案是添加一个 if 语句以确保仅当页面标题没有注册或登录时才调用获取默认时区。

"use strict";
$(document).ready(function() {
    var title = document.getElementsByTagName("title")[0].innerHTML;
    title = title.replace('Project X - ', '');
    if (title != 'Register' && title != 'Login') {
        $.ajax({
            url: location + '/get_timezone',
            success: function(resp) {
                new Clock(1000, resp);
            },
        });
    }
});
