我正在尝试在我拥有的表单上实现 SWFUpload。但是，它没有识别占位符。我的代码在下面，有人可以帮忙吗？如果有帮助，我正在使用 jQuery。

标题：

<script type="text/javascript" src="{{ MEDIA_URL }}/js/SWFUpload-2.5.0/swfupload/swfupload.js"></script>
<script type="text/javascript" src="{{ MEDIA_URL }}/js/SWFUpload-2.5.0/swfupload/swfupload.cookies.js"></script>
<script type="text/javascript" src="{{ MEDIA_URL }}/js/foo.js"></script>
<script type="text/javascript">
    $(swfupload("{% url swfupload %}","{{ MEDIA_URL }}/js/SWFUpload-2.5.0/swfupload/swfupload.swf"));       
</script>

身体：

<div id="upload_btn"></div>

Javascript（foo.js）：

swfupload = function(upload_url, flash_url) {
    var swfupload_real = new SWFUpload({
        debug: false,
        upload_url: upload_url,
        flash_url: flash_url,
        button_placeholder_id: "upload_btn",
        button_width: "40",
        button_height: "16",
        button_cursor: SWFUpload.CURSOR.HAND,
        button_text: "Click",
        file_size_limit: "20 MB",
        file_dialog_complete_handler: function() { this.startUpload(); },
        upload_complete_handler: function() { this.startUpload(); },
    });
};

编辑：我尝试查看 SWFUpload.js 的源代码，发现在它试图找到元素的时候，它会这样做：

targetElement = document.getElementById(this.settings.button_placeholder_id) || this.settings.button_placeholder;

我试着看看发生了什么，令人难以置信的是，在返回对象的document.GetElementByID同时返回 null $('#'+this.settings.button_placeholder_id)！我宁愿不修改库以使用另一个依赖项。有谁知道这可能是为什么？

我的 javascript 是 fubared。解决了以下问题：

<script type="text/javascript">
    upload_url = "{% url edit-story-swfupload %}";
    flash_url = "{{ MEDIA_URL }}/js/SWFUpload-2.5.0/swfupload/swfupload.swf";
    window.onload = swfupload_init;
</script>


swfupload_init = function() {
    var swfupload = new SWFUpload({
            debug: false,
            upload_url: upload_url,
            flash_url: flash_url,
            button_placeholder_id: "upload_btn",
            button_width: "40",
            button_height: "16",
            button_cursor: SWFUpload.CURSOR.HAND,
            button_text: "Click",
            file_size_limit: "20 MB",
            file_dialog_complete_handler: function() { this.startUpload(); },
            upload_complete_handler: function() { this.startUpload(); },
    });
}
