call of 10 news, At this point, if the number of pages is greater than 1, you will also need to display the next Page button for page loading, and, if there is a previous page, you need to display the previous page button to load the page. Name the next page button NEXTP, the previous page button is Previousp, and the state of both buttons is not visible by default.
Suppose that the XML file for the external file news is news.xml, the specific procedure is as follows:
var news_xml:xml = new XM

The parameterized log method supports multiple parameters. Compared with the preceding two methods, the overhead of constructing an Object [] is increased. Example:
Logger.info ("the value of the configuration item [{}] Read in the configuration file [{}] is [{}]", "/somePath/config. properties "," maxSize ", 5 );

First trip: A: I = 0, B: j = 1, 5 num = 2;
Second trip: A: I = 3, B: J = 5 num = 1;
Third trip: A: I = 4, B: J = 5 num = 1
Total: 2 + 1 + 1 = 4.
