This example introduces two new DOM attributes. First it uses the childNodes attribute to get the list of child nodes of mycel. The childNodes
list includes all child nodes, regardless of what their name or type
is. Like getElementsByTagName(), it returns a list of nodes. The
differences are that (a) getElementsByTagName() only returns elements of
the specified tag name; and (b) getElementsByTagName() returns
descendants at any level, not just immediate children. Once you have the
returned list, use [x] method to retrieve the desired
child item. This example stores in myceltext the text node of the second
cell in the second row of the table. Then, to display the results in
this example, it creates a new text node whose content is the data of
myceltext and appends it as a child of the <body> element.
If your object is a text node, you can use the data attribute and retrieve the text content of the node.
// first item element of the childNodes list of mycel
myceltext=mycel.childNodes[0];
// content of currenttext is the data content of myceltext
currenttext=document.createTextNode(myceltext.data);
mybody.appendChild(currenttext);
Getting an attribute value
At the end of sample1 there is a call to setAttribute on the mytable
object. This call was used to set the border property of the table. To
retrieve the value of the attribute, use the getAttribute method:
The bicycle industry has a long
history of using many different thread standards. Both factional and
metric sizes are in use. Some threads are also used almost exclusively
in the bicycle industry. Below is a table of some of the threads and
their uses. This table is not intended to be complete and exhaustive.
Always measure diameter and pitch when possible to determine threading.
