2, nodename syntax-----It is through the name of the element to determine the operation of the element, such as a div its ID name is called one, then when the judgment is written nodename== "one", and then by the method of obtaining a variable to manipulate the element. Note: The name of the element must be the ID name can be and the name of the element to be capitalized, in time to write the use of lowercase, but the judgment must be capitalized, otherwise it will not perform the effect.
