which are contained in the array returned by the ChildNodes property.However, each node has a NodeType property. The NodeType attribute has a total of 12 desirable values, but only 3 of them have value: The NodeType attribute value of the element node is 1, the property node's NodeType property value is 2, and the NodeType property value of the text node is 3.If you want to change the value of a text node, use the NodeValue property provided by the DOM.Array element Childnodes[0] There is a mor

Why do programmers need to study the art of programming? By sinp.

an array of objects, each corresponding to an element in the document that has the specified label name.This method allows a wildcard character to be * used as its argument, which returns all the label elements in the document as an array.3. GetelmentsbyclassnameThis method is a new method in the HTML5 DOM that accesses the element through the class name in the tag class attribute, which is an array of objects, each corresponding to the element in the document that has the specified class name.

To this day, it should be spent more than one months, and finally finished the DOM programming art (Appendix did not see), the above all the code is generally understood, because the book itself is relatively basic, not as authoritative and high-level programming as much content, covering more knowledge points.Dom This book is still very suitable for JS basic peo

This book is different from other R language Reference books in hand, and mainly interprets the R language from a programmatic perspective, not from a statistical perspective. Because these are not considered in depth, the code is often a collection of commands, not a "program", so hopefully learning this book will improve programming efficiency and make you more like a "programmer".This article corresponds to the "R Language

The art of maintenance Programming Recently, project personnel have changed, and they have been maintaining others' code for half of the time. Some of them are really uncomfortable. The main reason is that they didn't know much about maintenance programming at the beginning, I thought that I could learn something and calculate the workload. I don't know how ot

This is my senior year. Previously, due to stress, I went crazy to learn about software. Although the misunderstanding of blindly pursuing new technologies It does work a lot. Others are not mentioned, but Microsoft's. Net series: ado.net, Asp.net, jquery, LINQ, ajax.net, WCF, Silverlight, WPF ..... I believe many of my friends have learned this because it is almost a few of Microsoft's most popular technologies in recent years. Almost all technologies are used when getting started. "Hello

camel-named method is recommended. In JS, single or double quoted strings are semantically identical in the weakly typed language of JS; data types contain strings, numeric values, Boolean values, arrays (array subscripts starting from 0), objects.If the var keyword is used in a function, that variable is treated as a local variable that exists only in the context of the function, whereas if VAR is not used, that variable is treated as a global variable, and if a global variable with the same n
