解决uploadify在使用IE内核等浏览器无法使用

有两种方法：

第一种：

SWFUpload Version: 2.2.0 Beta 2
Flash Player Version: current
Operating System:Window 7

SWFUpload.prototype.getFlashHTML = function () {
 // Flash Satay object syntax: http://www.alistapart.com/articles/flashsatay
 return ['classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="', this.movieName, '" type="application/x-shockwave-flash" data="', this.settings.flash_url, '" width="', this.settings.button_width, '" height="', this.settings.button_height, '" class="swfupload">',
    '',
    '',

    ''].join("");
};

SWFUpload.prototype.getFlashHTML = function () {

 var obj = ['
