GetElementsByTagName
This method returns an array of objects (exactly a HTMLCollection collection, which is not an array in the real sense), each of which corresponds to an element in the document with a given tag. Similar to getElementById, this method provides only one parameter, which is the name of the specified tag. The sample code is as follows:
Document.getElementsByTagname ('li') / / li is the name of the tag
It is important to note that this method can be called not only by document objects, but also by ordinary elements. Examples are as follows:
Var demo = document.getElementById ('demo'); var lis = demo.getElementsByTagname (' li')
Similarly, this method is compatible with mainstream browsers, and even IE6+, can be used boldly.
