[JavaScript] Getelementsbyclassname with classname and getattribute!

The problem is not supported for getelementsbyclassname in JavaScript in IE 6/7/8.

Then the need to simulate the getelementsbyclassname needs to take the classname attribute, which involves the getattribute problem in JavaScript.

In IE 6/7, there is a bug for getattribute

Need to use ClassName to get the following:

var node = document.getElementById ("test"); var name = Node.classname;

For standard browsers, you can use classname directly or you can use Getattritbute, as a result:

Node.getattritbute ("class");

However, if it is IE 6/7, there is a problem with getattribute ().

So getelementsbyclassname can use the following methods:

Getelementsbyclazzname = Document.getelementsclassname? function (name) {return document.getelementsclassname (name);}:function (name) {var nodes = document.getElementsByTagName ("*"), result = [];for (var node in nodes) {if (Node.classname && Node.className.indexOf (name)) {Result.push (node);}} return result;}

The implementation here is relatively simple.

1: General properties recommended: Node.xxx.
2: Custom Attribute recommended: Node.getattribute ("xxxx").
3: It is recommended to use Node.getattribute ("xxx"), such as for in the label, when getting the target is a keyword in JavaScript.
4: When acquiring the target is reserved word, such as: class, please use ClassName instead.
