The following method gets the htmlcollection object Document. images // All IMG elements document. links // all elements a and area with the href attribute document. anchors // all elements a with the name attribute document. forms // All form

NodeList subnodelist = Rootnode.getchildnodes ();for (int i = 0; i System.out.println ("Node name of child node:" + Subnodelist.item (i). Getnodename ());SYSTEM.OUT.PRINTLN (node text content of child nodes: + Subnodelist.item (i). Gettextcontent ())

As a result, they always keep the latest and most accurate information. Essentially, all NodeList objects are queries that run in real time when accessing DOM documents. For example, the following code can cause an infinite loop: Copy Code

Remember last year's work encountered old IE and modern browser JS about DOM operation compatibility issues, in Chrome, IE, Firefox test getelementsbytagname return value, the problem arises, Both Chrome and opera return the NodeList object, while

NodeList objects are very similar in some ways and arrays, and it appears that you can directly use methods inherited from Array.prototype. However, in addition to the Foreach method, NodeList does not have these array-like methods.The inheritance

Convert nodelist to Arrays (compatibility)function Arrayofnodes (nodes) { varnull; Try { = Array.prototype.slice.call (nodes,0); } Catch (ex) { new Array (); for (var i=0,len=nodes.length; i ) { arr.push (

Definition: The length of the weighted path of a node is the product of the path length from the node to the root of the node and the permission on the node. The length of a tree's weighted path is the sum of the length of the weighted path of all

Dom Parsing In the DOM interface specification, there are four basic interfaces: Document, node, nodelist, and namednodemap. Among the four basic interfaces, the document interface is the entry for document operations, which is inherited from the
