Jquery FineUploader：在模板标记中添加上载按钮

使用fineUploader jQuery插件，我试图在fineUploader模板中添加几个上传按钮

但是，在将模板添加到DOM之前，

extraButtons

选项似乎不在模板内查找元素，只在DOM内查找

因此，如果extraButtons元素在模板内，fineUploader将找不到它们

我不想在模板外添加按钮。。。fineUploader能否在模板中定位额外按钮

我的fineUploader实例如下所示：

$("#fine-uploader").fineUploader({
        debug : true,
        extraButtons: [
            {element: $('#upload-pictures-btn1')},
            {element: $('#upload-pictures-btn2')},
            {element: $('#upload-pictures-btn3')}
        ],
        request: {
            endpoint: '/publish/upload'
        }
    });

实例关联处的JS错误：

未捕获类型错误：无法读取未定义的属性“style”

---

如果我将3个额外的按钮移出模板，并将它们直接放在我的HTML标记中，它就会起作用。但是我需要它们在模板中。

一个问题是您的代码。在Fine Uploader初始化之前，您正在从DOM中选择元素。当然，在创建Fine Uploader实例之前，这些元素还不存在，因为您已经在模板中定义了它们

当前，在设置

extraButton

选项时，您必须将

元素

传递给Fine Uploader，但确实存在。同时，一种可能的解决方法是创建自己的

，然后用户选择一个或多个文件。例如：

<input type="file" name="extraButton">
<script>
document.querySelector('input[name="extraButton"]').addEventListener('change', function(event) {
   uploader.addFiles(event.target);
});
</script>

document.querySelector（'input[name=“extraButton”]”）。addEventListener（'change'，函数（事件）{
uploader.addFiles（event.target）；
});

请显示您的代码。添加了代码详细信息和JS错误。我知道fineUploader找不到元素，因为模板尚未添加到DOM中。但我如何“传递每个元素的id并允许Fine Uploader为我选择它们”？这是fineUploader的一个功能吗？Thanx.没有为每个额外的按钮选项提供jquery对象，而是提供每个按钮的id。我尝试了

{element:“upload-pictures-btn1”}

和

{element:#upload-pictures-btn1”}

两种方法，但我出现了以下错误：

未捕获错误：[Fine Uploader 5.3.2]无法将样式应用于节点，因为它不在HtmleElement原型链上听起来像是代码中其他地方的问题。开发工具可能会很好地指出问题所在。请在我提到的GitHub案例中说明您的愿望。
