Tag provides a very compact notation for simple cases of conditionalized content 標(biāo)記為條件化內(nèi)容的一些簡單情形提供了一種非常簡潔的表示法。
Nesting additional scriptlets within the conditionalized content can wreak havoc if a syntax error is inadvertently introduced, and it can be quite a challenge to make sense of the resulting error message when the page is compiled by the jsp container 如果不經(jīng)意間引入了一個語法錯誤,則條件內(nèi)容中的嵌套其它scriptlet可能會造成嚴(yán)重破壞,并且在jsp容器編譯該頁面時,要使所產(chǎn)生的錯誤信息有意義可能會很困難。
