参考:

var acceptValue = makeMap('input,textarea,option,select');var mustUseProp = function (tag, type, attr) {  return (    (attr === 'value' && acceptValue(tag)) && type !== 'button' ||    (attr === 'selected' && tag === 'option') ||    (attr === 'checked' && tag === 'input') ||    (attr === 'muted' && tag === 'video')  )};
