SWFUpload flash文件上传使用集锦

1）、重写事件：

$.fn.imgbox = function(v) {
var s = {
key: '',
url: '',
source: [],
max: 0,
type: 'default',
button: 'swfUploadImageHolder',
hdkey: ''，
imgurl :'/images/upload.gif'
};
$.extend(s, v);

var swfu = new SWFUpload({
flash_url: '/swf/swfupload.swf',
flash9_url: '/swf/swfupload_fp9.swf',
upload_url: s.host + '/UploadImage.aspx?Key=' + s.key + '|' + s.type,
file_types: '*.jpg;*.png;*.gif',
file_types_description: 'Image Files',
file_upload_limit: s.max,//此处重写
file_queue_limit: 0,
custom_settings: { target: c },
debug: false,

button_placeholder_id: s.button,//此处重写

button_width: 39,
button_height: 24,
button_image_url: s.imgurl,//此处重写
button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,
button_cursor: SWFUpload.CURSOR.HAND,

file_queued_handler: imageQueued,
file_queue_error_handler: fileQueueError,
file_dialog_complete_handler: imgDialogComplete,
upload_start_handler: uploadStart,
upload_error_handler: uploadError,
upload_success_handler: imageSuccess
});

return c;
};

2、button_height：指定Flash按钮的高度，应该为button_image_url所指定的按钮背景图片高度的1/4。

所以更换按钮背景的的图标需要是button_height设置高度的4倍。比如图片高度是80(px)的，那么初始显示的高度是background-postion:0 0;那么当鼠标移到按钮上时(onmouseover)：显示图片的位置为：background-postion:0 -20px;参数参考：http://www.cnblogs.com/2050/archive/2012/08/29/2662932.html
