我刚刚将fineuploader CSS和JS文件放入我的项目中，并且遇到了JavaScript错误：
JavaScript TypeError: Cannot set property 'innerHTML' of null - ...fine-uploader/fine-uploader.js:7238
编辑：这是fine-uploader.js文件的这一部分：
qq.extend(this, {
render: function() {
log("Rendering template in DOM.");
generatedThumbnails = 0;
container.innerHTML = templateHtml.template; //<--this line
我的html（php）文件中有qq-template脚本，与提供的原始模板差不多：
<!DOCTYPE html>

最佳答案
您的Fine Uploader配置无效，因为您没有为Fine Uploader指定用于呈现模板的容器元素。
您需要添加一个容器元素，然后通过the element option在配置中引用它。
