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>



<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>";

?????? 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
