将谷歌图表添加到 vtiger 时出错

Question

Vtiger 有自己的 js 文件，所以我认为可能存在一些冲突。无论如何，这就是我在浏览器控制台中得到的：

主线程上的同步 XMLHttpRequest 已被弃用，因为 其对最终用户体验的不利影响。如需更多帮助 http://xhr.spec.whatwg.org/

错误：Google Charts loader.js 只能加载一次。

后者可能是因为 vtiger 两次调用 .tpl 文件，但我不知道为什么。

至于第一个警告：如果 jquery 附加外部 js 文件，这显然会发生。我还读到，如果 async 设置为 false，它应该可以工作，但我不知道如何在 vtiger 中做到这一点

如果我刷新页面一切都很好。

.tpl：

尝试在modules/(YOUR_MODULE)/views/Edit.php 中使用getHeaderScripts 添加您的js 文件。

    function getHeaderScripts(VtigerCrm_Request $request) {
            $headerScriptInstances = parent::getHeaderScripts($request);

            $jsFileNames = array(
                'libraries.jquery.multiplefileupload.jquery_MultiFile' 
            );
            // Add your js path like i did for jquery_MultiFile
            $jsScriptInstances = $this->checkAndConvertJsScripts($jsFileNames);
            $headerScriptInstances = array_merge($headerScriptInstances, $jsScriptInstances);
            return $headerScriptInstances;
    }
