We check whether either the start page or the end page number was greater than the total number of pages found and, if so, give an appropriate message. 我们检查起始页号和结束页(EP)号是否大于总页数,若是,则给出适当的消息。
When that condition is false, that is, the page counter is either less than the start page or greater than the end page, it does not write any output. 当那个条件为假(也就是说,页计数器的值小于起始页或大于结束页(EP))时,则selpg不再写任何输出。
The only extra thing is that we check that the end page given is not less than the start page. 唯一的额外工作是检查所给的结束页(EP)不小于起始页。
Use the HTML language on the front end page and the div + css format on page layout. Use the JavaScript language on the special efficiency and the interactive programme. 前端页面采用HTML语言,利用div+css的形式进行页面布局,使用JavaScript语言进行网站特效及页面信息交互的编程。
The save method is automatically called at the end of page execution if the automaticsaveenabled property is true. 如果automaticsaveenabled属性为true,则会在页面执行结束时自动调用save方法。
