解决SwfUpload在IE10上不出现上传按钮

????????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="','<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！
