GetElementsByName of solution in IE that is not valid for some elements

document.getElementsByName('someName')  Returns a list of nodes (array) 

Note: some nodes under the IE is no name attribute, is to use the document. The getElementsByName can't get. Only the following tag has the name attribute:
A, APPLET, attribute, BUTTON, EMBED, FORM, IMG, INPUT type= BUTTON, INPUT type=checkbox, INPUT type=file, INPUT type=hidden, INPUT type=image, INPUT type=password, INPUT type=radio, INPUT type=reset, INPUT type=submit, INPUT type=text, LINK, MAP, OBJECT, RT, RUBY, SELECT, TEXTAREA

Nothing else, div, span, etc

Alternative:

Premise: assume that the TagName of the acquired array of nodes is the same. (it is also rare that the nodes in the acquired node array are from different tags.)
