set name attribute in IE

今天遇到了一個很怪的bug，查到最後是一個動態產生的input沒有name的attribute，不論是用input.name = 'foo'; 或者 input.setAttribute('name', 'foo');都不會work，查了很久才發現這一篇文章，基本上算是個bug:
Setting the “name” attribute in Internet Explorer

The NAME attribute cannot be set at run time on elements dynamically created with the createElement method. To create an element with a name attribute, include the attribute and value when using the createElement method.

function createNamedElement(type, name) {
   var element = null;
   // Try the IE way; this fails on standards-compliant browsers
   try {
      element = document.createElement('<'+type+' name="'+name+'">');
   } catch (e) {
   }
   if (!element || element.nodeName != type.toUpperCase()) {
      // Non-IE browser; use canonical method to create named element
      element = document.createElement(type);
      element.name = name;
   }
   return element;
}
