swfupload感觉不是很舒服，不太习惯他的一些操作
测试代码后发现，事件代码必须有，否则无法正常上传图片
<script type="text/javascript">
var swfu;
window.onload = function () {
swfu = new SWFUpload({
// Backend Settings
upload_url: "upload.aspx",
post_params: {
"upload": "images"
},
//启动，用来使用querystring 传递参数，否则无法进行参数传递
use_query_string:true,
// File Upload Settings
//file_size_limit: "2 MB",
//file_types: "*.jpg",
//file_types_description: "JPG Images",
file_upload_limit: "0", // Zero means unlimited
// Event Handler Settings - these functions as defined in Handlers.js
// The handlers are not part of SWFUpload but are part of my website and control how
// my website reacts to the SWFUpload events.
file_queue_error_handler: fileQueueError,
file_dialog_complete_handler: fileDialogComplete,
upload_progress_handler: uploadProgress,
upload_error_handler: uploadError,
upload_success_handler: uploadSuccess,
upload_complete_handler: uploadComplete,
// Button settings
button_image_url: "js/swfupload/images/XPButtonNoText_160x22.png",
button_placeholder_id: "spanButtonPlaceholder",
button_ 160,
button_height: 22,
button_text: '<span class="button">选择文件<span class="buttonSmall">(最大10M)</span></span>',
button_text_style: '.button { font-family: Helvetica, Arial, sans-serif; font-size: 14pt; } .buttonSmall { font-size: 10pt; }',
button_text_top_padding: 1,
button_text_left_padding: 5,
// Flash Settings
flash_url: "js/swfupload/swfupload.swf", // Relative to this file
custom_settings: {

});
}
