SWFupload在IE9中无法点击bug解决方法

用swfupload是出现了再IE9下那选择文件的按钮无法点击的情况，在其他浏览器，例如Firefox、chrome都不会出现

出现这种情况，需要在swfupload.js中的getFlahHTML方法修改一下

SWFUpload.prototype.getFlashHTML = function (flashVersion) {
	// Flash Satay object syntax: http://www.alistapart.com/articles/flashsatay
    var obj = ['<object 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">'].join(""),params = [
		'<param name="wmode" value="',this.settings.button_window_mode,'" />','<param name="movie" value="','<param name="quality" value="high" />','<param name="menu" value="false" />','<param name="allowScriptAccess" value="always" />','<param name="flashvars" value="',this.getFlashVars(),'" />'
	].join("");
	if (navigator.userAgent.search(/MSIE/) > -1){
		obj = ['<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="','" class="swfupload">'].join("");
		params += '<param name="src" value="' + (this.support.imageResize ? this.settings.flash_url : this.settings.flash9_url) + '" />';
	}
	return [obj,params,'</object>'].join("");
};
