我不是一个真正的 javascript 程序员,但我已经为这个问题苦苦挣扎了很长时间 - 任何帮助将不胜感激。

在下面的 jsfiddle - 如果从框架和扩展选项卡中选择 Jquery,highcharts 图表可以正常工作。但代码的重点是我需要动态加载不同的 jquery 版本 - 将图表用作各种小部件。但是将其更改为无库(纯 JS)图表不会加载。

我从这里得到的大部分代码:http: //alexmarandon.com/articles/web_widget_jquery/

非常感谢

尽管 alexmarandon.com 网络小部件教程提到了其他库,但您的情况可能更适合全动态“链式加载”方法。一旦 jquery 动态加载完成,不要直接转到 main(),而是继续并动态链接加载 Highcharts。再添加一个函数,删除对 Highcharts.js 的静态外部引用,然后用调用此 chainLoadHighchharts() 函数替换对 scriptLoadHandler() 的调用,然后该函数本身将传递给原始 scriptLoadHandler()。

    function chainLoadHighCharts() {
    var Highcharts;
    /********  Ok, /now/ dynamically load up highchart too... *********/
    if (window.Highcharts === undefined) {
        var script_tag = document.createElement('script');
        script_tag.setAttribute("type", "text/javascript");
        script_tag.setAttribute("src",
            "http://code.highcharts.com/highcharts.js");
        if (script_tag.readyState) {
            script_tag.onreadystatechange = function () { // For old versions of IE
                if (this.readyState == 'complete' || this.readyState == 'loaded') {
                    scriptLoadHandler(); //here is the call that was orginally called directly from the jquery dynamic load.
                }
            };
        } else {
            script_tag.onload = scriptLoadHandler;
        }
        // Try to find the head, otherwise default to the documentElement
        (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
    } else {
        scriptLoadHandler();

        //  script_tag.setAttribute("src","http://code.highcharts.com/modules/exporting.js");
    }
}

仍然需要一点点收紧,但它在 jsfiddle 上运行对我来说没有错误。
