一、去掉Birt表格下自动生成的日期时间
在报表下点击Xml Source标签,打开xml,找到
<page-setup>
<simple-master-page name="Simple MasterPage" id="2">
<page-footer>
<text id="3">
<property name="contentType">html</property>
<text-property name="content"><![CDATA[<value-of>new Date()</value-of>]]></text-property>
</text>
</page-footer>
</simple-master-page>
</page-setup>
把
<text id="3">
<property name="contentType">html</property>
<text-property name="content"><![CDATA[<value-of>new Date()</value-of>]]></text-property>
</text>
这几行去掉即可。
二、Birt表格隔行换颜色
1、 鼠标旋停在表格上,选择Row Detail一行;
2、 选择script标签页,打开birt的脚本编辑窗口;
3、 从下拉列表中选择OnCreate,在下面加入Javascript脚本如下:
if(row.__rownum % 2 == 0){
this.getStyle().backgroundColor = "#E9EAEB";
}else{
this.getStyle().backgroundColor = "#FFFFFF";
}
4、 保存
三、Birt表格分页
下面是我从网上找的方法,我试了一下不行,后来我在table里设置了Page break interval就可以了,但是预览的时候不能看到分页
1、鼠标旋停在表格上,选择Row Detail一行;
2、选择script标签页,打开birt的脚本编辑窗口;
3、从下拉列表中选择onPrepare,在下面加入Javascript脚本如下:
var count = 0;
4、从下拉列表中选择OnCreate,在下面加入Javascript脚本如下:
count++;
if(count % 10 == 0){
style.pageBreakAfter = "always";
}
5、保存,使用Web Reviewer进行预览,数据可以进行分页显示了。注意不要使用Preview标签页进行浏览,这个标签页的浏览效果是不分页的。发布到web工程上,也可以进行分页显示了。
四、BIRT报表添加时间控件的方法
birt再传递参数时候,很多报表需要有时间段的参数,为简化用户操作,日历控件是个很好的选择,在birt里也能实现日历控件的方法,效果如图:
实现方法:
首先需要引入一个Calendar.js脚本,将此脚本放置于WebRoot>webcontent>birt>ajax>utility下,
Calender.js内容如下:
<!--
var cal_Width = 180;//定义日历显示的宽度,至少140
document.write("<div id='meizzCalendarLayer' style='position: absolute; z-index: 9999; width: " + (cal_Width+4).toString() + "px; height: 193px; display: none'>");
document.write("<iframe name='meizzCalendarIframe' scrolling='no' frameborder='0' width='100%' height='100%'></iframe></div>");
var WebCalendar = new WebCalendar();
function document.onclick()
{
if(WebCalendar.eventSrc != window.event.srcElement) hiddenCalendar();
}
function WebCalendar() //初始化日历的设置
{
this.regInfo = "关闭的快捷键:[Esc]";
this.dayShow = 35; //定义页面上要显示的天数,不能小于35,或大于39
this.daysMonth = new Array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
this.day = new Array(this.dayShow); //定义日历展示用的数组
this.dayObj = new Array(this.dayShow); //定义日期展示控件数组
this.dateStyle = null; //保存格式化后日期数组
this.objExport = null; //日历回传的显示控件
this.eventSrc = null; //日历显示的触发控件
this.inputDate = null; //转化外的输入的日期(d/m/yyyy)
this.thisYear = new Date().getFullYear(); //定义年的变量的初始值
this.thisMonth = new Date().getMonth()+ 1; //定义月的变量的初始值
this.thisDay = new Date().getDate(); //定义日的变量的初始值
this.today = this.thisDay +"/"+ this.thisMonth +"/"+ this.thisYear; //今天(d/m/yyyy)
this.iframe = window.frames("meizzCalendarIframe"); //日历的 iframe 载体
this.calendar = getObjectById("meizzCalendarLayer"); //日历的层
this.dateReg = ""; //日历格式验证的正则式
this.yearFall = 5; //定义显示的年份下拉框的年差值,如果今年是2000年,这里设置为50,就显示1950-2050
this.format = "yyyy-mm-dd"; //回传日期的格式
this.timeShow = false; //是否返回时间
this.drag = true; //是否允许拖动
this.darkColor = "#95B7F3"; //控件的暗色
this.lightColor = "#FFFFFF"; //控件的亮色
this.btnBgColor = "#E6E6FA"; //控件的按钮背景色
this.wordColor = "#000080"; //控件的文字颜色
this.wordDark = "#DCDCDC"; //控件的暗文字颜色
this.dayBgColor = "#F5F5FA"; //日期数字背景色
this.todayColor = "#FF0000"; //今天在日历上的标示背景色
this.DarkBorder = "#D4D0C8"; //日期显示的立体表达色
this.yearOption = "";
var yearNow = new Date().getFullYear();
yearNow = (yearNow <= 1000)? 1000 : ((yearNow >= 9999)? 9999 : yearNow);
var yearMin = (yearNow - this.yearFall >= 1000) ? yearNow - this.yearFall : 1000;
var yearMax = (yearNow + this.yearFall <= 9999) ? yearNow + this.yearFall : 9999;
yearMin = (yearMax == 9999) ? yearMax-this.yearFall*2 : yearMin;
yearMax = (yearMin == 1000) ? yearMin+this.yearFall*2 : yearMax;
for (var i=yearMin; i<=yearMax; i++) this.yearOption += "<option value='"+i+"'>"+i+"年</option>";

然后修改WebRoot>webcontent>birt>pages>layout>FramesetFragment.jsp,找到
<script src="birt/ajax/core/BirtSoapResponse.js" type="text/javascript"></script>,
再下面加上
<script src="birt/ajax/utility/Calendar.js" type="text/javascript"></script>。
然后再修改WebRoot>webcontent>birt>pages>parameter>TextBoxParameterFragment.jsp,找到
INPUT CLASS="BirtViewer_parameter_dialog_Input"
再里面的ID="<%= encodedParameterName %>" 下面加上
<%if (encodedParameterName.indexOf("Date")>=0) {%>
onclick="calendar()"
<%} %>
注意此处的含义是如果参数名中含有"Date",则调用日历控件,这是因为无法判断参数属性,所以要检查参数名称是否含有Date,定义参数的时候也要加上"Date",比如fromDate,endDate等。参数要使用文本框格式,属性设置为String
注:此方法暂不支持Firefox,如果想要再FF下也能使用日历控件,可以用http://www.my97.net/dp/demo/这个日历控件,此控件功能更强大,使用方法与上面的类似。
特别说明:日历控件的使用必须要把报表部署到tomcat或其他容器下,用预览模式不能使用日历控件!
四、Birt部署在tomcat下的方法
1、先下载birt-runtime-2.1.3.zip 地址:http://www.eclipse.org/downloads/download.php?file=/birt/downloads/drops/R-R1-2_1_3-200707051847/birt-runtime-2.1.3.zip
2、将其解压,把目录下的WebViewerExample文件夹复制到Tomcat主目录下的webapps目录下,并改名为birtApp.
3、复制第三方软件:
- itext-1.5.2.jar:复制到birtApp/WEB-INF/platform/plugins/com.lowagie.itext/lib
- 数据库驱动(mysql为例)mysql-connector-java-5.0.5-bin.jar:复制到birtApp/WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_2.1.1.v20070705-1847/drivers
不过我用的2.1.3版本不用复制itext-1.5.2.jar,相应目录下面都有,也不用复制其他的jar文件。但数据库驱动的jar文件一定要复制(不过报表中没用到数据库访问的话就不用了)!
如果是用tomcat6的版本,需要在工程的Web-INF/lib下放置一个commons-logging-api-1.1.1.jar的包,这个包在tomcat5.5里有,6.0取消了这个包
4、启动Tomcat,在浏览器中输入http://lcoalhost:8080/birtApp/ 在首页中点击"View Example",若正常进入,则说明成功。
5、发布做好的报表文件:将制作好的报表文件如test.rptdesign复制到birtApp下,在浏览器中输入:
http://localhost:8080/birtApp/run?__report=test.rptdesign 就可以访问了。
6、访问报表:http://localhost:8080/birtApp/frameset?__report=报表文件路径
这个web应用支持2个动作:
-
frameset,以frameset的形式显示报表。这个界面包含一些frame,如页面导航,报表主体在其中的一个frame中显示;使用形式:
http://localhost:8080/birtApp/frameset?__report=报表文件路径&参数=........ -
run,报表以一个单独的html页面或pdf显示,由于这种形式没有frmaeset,因此使用者必须自己提供相应的参数,如报表参数,页号等。使用形式:
http://localhost:8080/birtApp/run?__report=报表文件路径&参数=........
对于以上2个动作,以下列出可用的参数:
- __format:报表输出格式:html或pdf,缺省是html。对于frameset不起作用。
- __isnull:指明一个参数是null,常用于字符串类型。如果提供参数且值为空: - 对于日期和数字类型,BIRT会将它们当作null处理。 - 对于字符串,BIRT会将它作为空字符串。因此,为了说明某个字符串是null,通常写为:__isnull=参数。
- __locale:本地化选项,缺省是jvm的locale。
- __report:报表设计文件路径。
- 报表参数:报表参数参数值对,形式:参数名=参数值。对于frameset,直接在地址栏中输入参数名=参数值后回车,不会影响报表结果。虽然,此时选择"运行报表"时,弹出的参数值已经改变。
五、Birt设置公用样式(Style)及公用数据源(DataSource)的方法
一、先说设置公用样式:
1.右键单击工程,选择new>Other>Web>CSS,建立一个CSS文件,比如birt.css
2.在birt.css里写样式,如果CSS不熟的话,可以到我的CSDN共享资源里下载,下载地址是(http://download.csdn.net/source/1207675),这个报表能应付一般简单的表格
3.点一个报表文件,选择Layout标签,然后再Outline窗口下看到Styles,下面有两个默认的Style,可以先删除。然后右键单击Styles,选择"Use CSS File...",找到刚才建立的birt.css
4.然后就OK了,如果修改了birt.css,只需要右键单击Outline窗口下的Styles的birt.css,选择"Reload CSS File"
二、再说公用数据源的方法
1.右键单击工程,选择new>Library,起个名字叫ds.rptlibrary
2.在Outline窗口下选择Data Sources,选择JDBC Data Source,然后填入连库字符串及用户名密码
3.这样数据源就建立好了。
4.新建报表后,再Outline窗口下,右键单击Libraries,选择Use Library,选择刚才新建的ds.rptlibrary
5.使用ds我一直没有找到方法,老是找不到怎么把ds引入到Data Sources下,只好修改源代码了,选择报表下面的XML Source 标签,再 </list-property>后面下粘贴下面的语句
<data-sources>
<oda-data-source extensionID="org.eclipse.birt.report.data.oda.jdbc" name="Data Source" id="1350"
extends="ds.Data Source"/>
</data-sources>
注意id=1350不能和报表中其他的id重复。
然后就能看到Outline窗口下Data Sources下面多了一个Data Source的链接,说明建立成功

六、BIRT中的日期时间必须为String类型。
七、BIRT报表设置时间参数。(添加时间控件的方法可以参考网上的资料。这里没有使用时间控件的方法。)
例子如下:
北京移动各产品用户发展综合情况日监控表数据集如下:
select * from bi_ui.v_syf_t8 t
where substr(report_date, 1, 4) = ?
and substr(report_date, 5, 2) = ?
and substr(report_date, 7, 2) = ?
yearSet如下:
select * from bi_ui.ui_dim_date_year dy where dy.year_value <= to_char(sysdate, 'yyyy')
monthSet如下:
select * from bi_ui.ui_dim_date_month
daySet如下:
select * from bi_ui.ui_dim_date_day
北京移动各产品用户发展综合情况日监控表数据集【参数】添加如下:
创建参数组,参数组中添加year、month、day参数。以下是year设置。
数据类型:字符串
显示类型:列表框
选择【动态】:
数据集:yearSet
选择值列:YEAR_VALUE
选择显示文本:YEAR_DESC
