1. logon界面解析：

JS 验证用户名、密码为空

<form name="form1" method="post" action="manager.do?action=login">

　　<input name="name" type="text" class="logininput" id="name" size="27">

　　<input name="pwd" type="password" class="logininput" id="pwd" size="27">

　　<input name="Submit" type="submit" class="btn_grey" value="确定" onClick="return check(form1)">

</form>
function check(form){

    if (form.name.value==""){

        alert("请输入管理员名称!");form.name.focus();return false;

    }

    if (form.pwd.value==""){

        alert("请输入密码!");form.pwd.focus();return false;

    }

}

重置用户名、密码：

<input name="Submit3" type="reset" class="btn_grey" value="重置">

2.main.jsp解析

引用其他jsp文件

<%@include file="banner.jsp"%>

<%@include file="navigation.jsp"%>

直接在jsp页面中调用DAO

<%

BorrowDAO borrowDAO=new BorrowDAO();

Collection coll_book=(Collection)borrowDAO.bookBorrowSort();

%>

html夹杂java代码

<%if(coll_book!=null && !coll_book.isEmpty()){

                          Iterator it_book=coll_book.iterator();

                          int i=1;

                      int degree=0;

                      String bookname="";

                      String typename="";

                      String barcode_book="";

                      String bookcase="";

                      String pub="";

                      String author="";

                      String translator="";

                      Float price=new Float(0);

                          while(it_book.hasNext() && i<6){

                          BorrowForm borrowForm=(BorrowForm)it_book.next();

                        bookname=borrowForm.getBookName();

                            barcode_book=borrowForm.getBookBarcode();

                            typename=borrowForm.getBookType();

                        degree=borrowForm.getDegree();

                        bookcase=borrowForm.getBookcaseName();

                            pub=borrowForm.getPubName();

                            author=borrowForm.getAuthor();

                            price=borrowForm.getPrice();

                        %>

                  <tr>

                    <td height="25" align="center"><%=i%></td>

                    <td style="padding:5px;">&nbsp;<%=barcode_book%></td>

                    <td style="padding:5px;"><%=bookname%></td>

                    <td style="padding:5px;"><%=typename%></td>

                    <td align="center">&nbsp;<%=bookcase%></td>

                    <td align="center">&nbsp;<%=pub%></td>

                    <td width="11%" align="center"><%=author%></td>

                    <td width="8%" align="center"><%=price%></td>

                    <td width="8%" align="center"><%=degree%></td>

                  </tr>

                        <%

                        i++;

                        }

                    }%>
