Getelementsbyname () is invalid for some elements (such as span)

Document. getelementsbyname ('somename') returns a node list (array)

Note: Some nodes in IE do not have the name attribute, but they cannot be obtained using document. getelementsbyname. Only the following tags have 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

None of them, such as Div and span.
