这段代码是用于实现一个表单跳转到指定页数的功能。它首先获取了表单中的总页数,然后检查输入的跳转页数是否是数字,如果不是则弹出提示框并返回 false。如果输入的页数大于总页数,则跳转到最后一页。最后,根据跳转的页数设置表单的 action 属性并提交表单。该代码是使用 JSP 编写的,其中使用了一些 JSP 的语法,如 `<%=basePath%>`。

function top2(){ form3.action="<%=basePath%>admin/cw/index.jsp?page=1"; form3.submit(); } function last2(){ if(form3.pageCount.value==0){//如果总页数为0,那么最后一页为1,也就是第一页,而不是第0页 form3.action="<%=basePath%>admin/cw/index.jsp?page=1"; form3.submit(); }else{ form3.action="<%=basePath%>admin/cw/index.jsp?page="+form3.pageCount.value; form3.submit(); } } function pre2(){ var page=parseInt(form3.page.value); if(page<=1){ alert("已至第一页"); }else{ form3.action="<%=basePath%>admin/cw/index.jsp?page="+(page-1); form3.submit(); } } function next2(){ var page=parseInt(form3.page.value); var pageCount=parseInt(form3.pageCount.value); if(page>=pageCount){ alert("已至最后一页"); }else{ form3.action="<%=basePath%>admin/mb/index.jsp?page="+(page+1); form3.submit(); } }
这段代码是一个用于实现分页功能的 JavaScript 代码。它定义了四个函数:top2()、last2()、pre2() 和 next2()。其中,top2() 和 last2() 分别用于将分页导航跳转到第一页和最后一页,pre2() 和 next2() 分别用于将分页导航跳转到上一页和下一页。它们通过修改 form3 的 action 属性,并提交表单来实现分页导航的跳转。其中,form3 是一个表单元素,它包含了用于分页的参数,如当前页码和总页数。需要注意的是,该代码中存在一个错误,即在 next2() 函数中,将 form3.action 设置为 "<%=basePath%>admin/mb/index.jsp?page=",而应该是 "<%=basePath%>admin/cw/index.jsp?page=",否则将会导致跳转到错误的页面。
修改这段代码 <td colspan="6"> <a href="PageServlet?pageNo=1&totalPage=${list.totalPage}">首页</a> <a href="PageServlet?pageNo=${list.pageNo-1}&totalPage=${list.totalPage}">上一页</a> <a href="PageServlet?pageNo=${list.pageNo+1}&totalPage=${list.totalPage}">下一页</a> <a href="PageServlet?pageNo=${list.totalPage}&totalPage=${list.totalPage}"> 最后一页 </a> <br/> 跳转到: <input id="pageNo" type="text" class="form-control form1" name="pageNo" value="${list.pageNo}" /> 每页记录数: <input class="form-control form1" type="text" name="pageCount" value="${list.pageCount}" /> <input class="btn btn-primary" type="submit" value="跳转" /> 共有 ${list.totalPage} 页 </td>
This code appears to be generating HTML for a pagination section of a web page. In order to modify this code, you would need to specify what changes you want to make. Here are some possible modifications that you could make:
- Change the text of the pagination links (e.g. "首页", "上一页", etc.) to different words or phrases
- Change the styling of the pagination section using CSS
- Add additional links or controls to the pagination section (e.g. a dropdown menu to select a specific page number)
- Change the layout of the pagination section (e.g. move the "跳转到" input field to a different location)
Please let me know what specific changes you would like to make and I can provide more guidance.
