Set the variable scope to limit variables to live only within a " session " 。還要設(shè)置變量作用域,以限制變量只在某個“會話”中活動。
Variables have limited scope and are not part of the persistent database , they are not affected by transaction rollbacks 變量作用域有限,并且不是持久數(shù)據(jù)庫的一部分,因而不受事務(wù)回滾的影響。
For example , the explanation of stacks and register frames in chapter 6 connected with chapter 4 s explanation of variable scope 例如,在第6章中對棧和寄存器結(jié)構(gòu)的解釋要聯(lián)系到第4章中對變量作用域的解釋。
Page is the default scope given to all data within your jsp page , and it allows you to use this data within the boundaries specified for local variables class method local variable scope Jsp頁面內(nèi)所有數(shù)據(jù)的默認作用域都是page ,它允許您在為局部變量指定的范圍內(nèi)(類/方法/局部變量作用域)使用這種數(shù)據(jù)。
