Javascript Functions limit the calling code. For more information, see. Function:
The Code is as follows:
Function throttle (fn, MS ){Var last = (new Date (). getTime ();Return (function (){Var now = (new Date (). getTime ();If (now-last> MS ){Last = now;Fn. apply (this, arguments );}});}

run after each item is processed, which may avoid long-running script errors.function throttlingThe idea of a function throttle is that some code cannot be repeated continuously without interruption. The first time the function is called, a timer is created to run the code after the specified interval. When the function is called the second time, the previous timer is cleared and the other one is set. The code ideas are as follows:Function
number of concurrent writes during backup is large, the xtrabackup_logfile may be large (5 GB +) and may be full of your/tmp directory, you can solve this problem by specifying the directory with the -- tmpdir parameter.
-- Tmpdir = DIRECTORY
When -- remote-host or -- stream is specified, the temporary directory of transaction logs is stored. the tmpdir directory specified in the MySQL configuration file is used by default.

8. Drying Filter
The water vapor in the absorption refrigeration system may be filled with silica gel). There are two reasons for the moisture. One is that the drying is not strict, second, the use of unqualified refrigerant will produce ice blocking, And the refrigerant reflects the production of hydrochloric acid and other hazards. It is also necessary to filter out possible metal impurities in the coolin

layouts and responses.Common parallax scrolling effects sites and similar complex layout sites often use JavaScript to calculate size and location. If the user resizes the browser, the size and position do not change as the changes occur. Listen for the event on the window, and invoke a function that calculates the size and position when triggered, and can be recalculated based on the size of the browser.However, it is important to note that when any change in the browser will trigger the resiz
