SwfUpload在IE10上不出现上传按钮的解决方法

在系统测试过程中，发现使用了SwfUpload实现的无刷新上传功能，在IE10上竟然无法使用了，难道SwfUpload不支持吗?还是需要换一种实现方式呢？最后通过了解SwfUplad.JS文件发现，我们是可以修改的，让其支持IE10,具体解决方案如下：

打开SwfUpload.js，在js文件中找到// Private: getFlashHTML generates the object tag needed to embed the flash in to the document”这行和“// Private: getFlashVars builds the parameter string that will be passed”和这行，然后把中间的用如下代码替换就OK了

SWFUpload.prototype.getFlashHTML = function (flashVersion) { 
// Flash Satay object syntax: http://www.alistapart.com/articles/flashsatay 
var classid = ""; 
var Sys = {}; 
var ua = navigator.userAgent.toLowerCase(); 
if (window.ActiveXObject) { 
Sys.ie = ua.match(/msie ([\d.]+)/)[1]; 
if (Sys.ie && Sys.ie.substring(0, 1) == "9" || Sys.ie.substring(0, 2) == "10") { 
classid = ' classid = "clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"'; 
} 
} 
return ['<object', classid, ' id="', this.movieName, '" type="application/x-shockwave-flash" data="', (this.support.imageResize ? this.settings.flash_url : this.settings.flash9_url), '" width="', this.settings.button_width, '" height="', this.settings.button_height, '" class="swfupload">', 
'<param name="wmode" value="', this.settings.button_window_mode, '" />', 
'<param name="movie" value="', (this.support.imageResize ? this.settings.flash_url : this.settings.flash9_url), '" />', 
'<param name="quality" value="high" />', 
'<param name="allowScriptAccess" value="always" />', 
'<param name="flashvars" value="' + this.getFlashVars() + '" />', 
'</object>'].join(""); 
};

保存，运行就可以看到效果了，完美！
