Tinys is a tiny selector for DOM

It is actually homework of Labmu.

The usage is quite simple.

Function $(sel) is a selector which can return the nodes that match the parameters you feed to it.

sel is a string pattern you use to specify the limitations. So far, there have been three types.

• #id-name specifies the id of the node
• .class-name specifies the class name of the nodes
• tag-name specifies the tag name of the nodes

At present, you can only use exactly one such pattern of any type out of the three available ones listed above. You cannot use combinations of these patterns.

• If there is no matched node, the selector returns null
• If there is exactly one matched node, the selector returns that node packed in a window.TNode instance
• Otherwise, the selector returns an array containing all the nodes each of which is packed in a window.TNode instance.

The method attr(attrName, val) will set the attribute named attrName of the node to val. Both attrName and val should be strings.

The method attr(attrName) will return the value of the attribute named attrName of the node to val. If there is no such attribute, undefined is returned instead.
