Internet Explorer 8 and later can set the NAME attribute at run time on elements dynamically created with the createElement method. To create an element with a NAME attribute in earlier versions of Internet Explorer, include the attribute and its value when using the createElement method.

var element = null;
try {
// IE6/IE7 構(gòu)建方式
element = document.createElement('<input name="radio-button">');
} catch (e) {
// W3C 構(gòu)建方式
element = document.createElement('input');
element.name = 'radio-button';
}
// 定義其他屬性
element.id = 'radio-1'
element.type = 'radio';
