Default settings:
Googl

If you want to do "continue" in an .each() loop, you can use below code segment to implement it.$('div').each(function (index, el) { if (index == 0) { return true; } });

Client-side table sorting for flexigrid

----------------------------------------------------------------------------------------
I wrote a function to perform sorting of the table locally instead of
making a trip to the server each time. It uses the ".sorted" class to
determine which column needs sorting, thus only the table selector is
passed along with the sort order. At this stage it supports alphabetic
and (slightly crude) numeric sorting. I hope this

事务的传播性

1.Required：共享型
若1处在一个事务中调用了2，则2直接和1在同一个事务中。若1没有任何事务，则系统会默认给2创建一个新事务。此策略适合大多数情况。
2.RequiredNew：独立型
若1在一个事务中调用了2，则系统先将1的事务挂起，不管、之后为2设置一个新事务，执行完毕后恢复1的事务。若1没有事务，则会为2新开一个事务。
3.Mandatory：强制共享型
若1处在一个事务中调用了2，则2直接和1在同一个事务中。若1没有任何事务，直接抛出异常——Transaction RequiredException。
4.NotSupported：无助独立型
若1在一个事务中调用了2，则系统先将1的事务挂起，不管、之后2不开启任何事务，执行完毕后恢复1的事务。若1没有事务，2也直接执行。
5. Supported：啃老型
若1处在一个事务中调用了2，则2直接和1在同一个事务中。若1没有任何事务，直接执行2。
6.Never：捣乱型
若1处在一个事务中调

org.springframework.security.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext

李涛 — Tue, 24 May 2011 12:50:00 +0800

Reference:
