Question

我刚刚在我的项目中添加了fineuploader CSS和JS文件，并且出现了javascript错误：

JavaScript TypeError: Cannot set property 'innerHTML' of null - ...fine-uploader/fine-uploader.js:7238

编辑：这是fine-uplo.js文件的一部分：

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，就像提供的vanilla模板一样：

<!DOCTYPE html>

    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

Answer 1

您的Fine Uploader配置无效，因为您没有为Fine Uploader指定容器元素来呈现模板。

您需要添加容器元素，然后通过the element option在配置中引用它。

找不到默认模板
