javascript - jquery函数不支持

Question

我有一个 jQuery 插件 tzineClock。但是当我尝试调用它时

$(document).ready(function(){
    /* This code is executed after the DOM has been completely loaded */
    $('#fancyClock').tzineClock();
});

它正在抛出错误，因为“不支持此功能”。谁能告诉我错误可能是什么？这是 tzineClock 代码:

$.fn.tzineClock = function(opts){

        // "this" contains the elements that were selected when calling the plugin: $('elements').tzineClock();
        // If the selector returned more than one element, use the first one:

        var container = this.eq(0);     
        if(!container)
        {
            try{
                console.log("Invalid selector!");
            } catch(e){}

            return false;
        }

        if(!opts) opts = {}; 

        var defaults = {
            /* Additional options will be added in future versions of the plugin. */
        };

        /* Merging the provided options with the default ones (will be used in future versions of the plugin): */
        $.each(defaults,function(k,v){
            opts[k] = opts[k] || defaults[k];
        })

        // Calling the setUp function and passing the container,
        // will be available to the setUp function as "this":
        setUp.call(container);

        return this;
    }

这可能是因为 jQuery 尚未加载 tzineClock 函数，因此它“不受支持”。

检查您引用插件的脚本标签，并确保 tzineClock 脚本标 checkout 现在 jQuery 脚本标签之前。

如果这没有什么区别，您能否向我们提供导致错误的行和文件，并确保脚本文件已使用任何浏览器开发工具实际加载.
