图片上传按钮不显示

解决方法：

打开swfupload.js文件找到307行开始的如下代码：

// Private: getFlashHTML generates the object tag needed to embed the flash in to the document
SWFUpload.prototype.getFlashHTML = function (flashVersion) {
    // Flash Satay object syntax: http://www.alistapart.com/articles/flashsatay
    return ['<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">',
                '<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("");
};



将其替换为：


// Private: getFlashHTML generates the object tag needed to embed the flash in to the document
SWFUpload.prototype.getFlashHTML = function (flashVersion) {
    // Flash Satay object syntax: http://www.alistapart.com/articles/flashsatay

    //处理IE9中不显示上传按钮的情况
    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") {
        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("");
};
