我创建了函数来发送带有指向我的网站的反向链接的电子邮件，我正在使用代码点火器框架
用户单击电子邮件上的特定链接（反向链接）后，用户将重定向到具有iframe的"我的页面"。
我使用该iframe提交带有文件输入的表单，而无需刷新页面。
当用户在IE9浏览器中使用gmail通过该链接时，form.submit()功能失败，在其他浏览器中它可以正常工作，其他电子邮件（gmail除外）也是如此。
请帮助我找到解决方案
谢谢。

实际上我正在使用 ajaxupload jquery 库，它在上述情况下form.submit();行失败
/* Creates form, that will be submitted to iframe
* @param {Element} iframe Where to submit
* @return {Element} form
*/
_createForm: function(iframe){
var settings = this._settings;
// We can't use the following code in IE6
// var form = document.createElement('form');
// form.setAttribute('method', 'post');
// form.setAttribute('enctype', 'multipart/form-data');
// Because in this case file won't be attached to request
var form = toElement('<form method="post" enctype="multipart/form-data"></form>');
form.setAttribute('action', settings.action);
form.setAttribute('target', iframe.name);
form.style.display = 'none';
document.body.appendChild(form);
// Create hidden input element for each data key
for (var prop in settings.data) {
if (settings.data.hasOwnProperty(prop)){
var el = document.createElement("input");
el.setAttribute('type', 'hidden');
el.setAttribute('name', prop);
el.setAttribute('value', settings.data[prop]);
form.appendChild(el);
}
}
return form;
},

检查代码是否在 iframe 中，如果没有在 form.submit() 中指定 iframe，即
document.iframename.form.submit();
