显示“Y的页面X”使用单个文本字段 [英] Show "Page X of Y" using a single text field

问题描述

我想创建一个包含 Y 的第X页的文本字段，而不按照常用解决方案将其拆分为两部分。我的文本字段包含Page+ $ V {currentPage} +of+ $ V {PAGE_NUMBER}， evaluationTime = auto 。

假设我有一个10页的报告。其中三个是标题带，六个是细节带，其中一个是摘要频段。标题频段，我的结果显示第0页，共10页 s，摘要带的细节带，然后第0页，共10页的正确计数。

你如何确保在任何地方计算变量，不仅仅是细节带？

解决方案

Jaspersoft Studio，6 +

对于Jaspersoft Studio v6，或者如果第一个页码重复，请尝试

将表达式设置为 1 可防止其值 null 。也就是说，如果页脚显示 Page null 为4 ，则可能表示尚未设置表达式。

创建变量。

添加页脚

添加 Page Footer 乐队如下：

1. 在大纲面板中选择报告


2. 检查页面页眉和页脚的摘要以确保页面页脚显示在摘要页面上。


3. 添加页脚条带。

页脚已添加。

创建文本字段

创建一个文本字段，如下所示：

1. 拖放单个文本字段到页面页脚区域。


2. 选择文本字段。


3. 设置表达式 to： msg（{1}的页面{0}，$ V {V_CURRENT_PAGE_NUMBER}，$ V {PAGE_NUMBER}）


4. 设置 Evalutat离子时间到：自动

这些设置如图所示下图：

预览报告

对于包含三个页面和摘要页面的报告，预览报告显示：

摘要页面显示：

I would like to create one text field that contains Page X of Y, without splitting it in two parts, as per the common solution. My textfield contains "Page " + $V{currentPage} + " of " + $V{PAGE_NUMBER}" with evaluationTime=auto.

Let's say I have a report with 10 pages. Three are the Title Band, six are Detail Band and one is the Summary Band. My results show "Page 0 of 10" for the Title Bands, correct counts for the Detail Bands, then "Page 0 of 10" for the Summary Bands.

How do you ensure the variable is calculated everywhere, not only on Detail Band?

解决方案

Jaspersoft Studio, 6+

For Jaspersoft Studio v6, or if the first page number is duplicated, try this solution, which uses $V{MASTER_CURRENT_PAGE} and $V{MASTER_TOTAL_PAGE} with an evaluation time of Master.

Jaspersoft Studio

For other versions of Jaspersoft Studio, try the steps outlined in the subsequent subsections.

Create Variable

Create a variable as follows:

1. Create a variable called V_CURRENT_PAGE_NUMBER
2. Select the variable to open its properties (illustrated below)
3. Set Expression to: 1
4. Set Initial Value Expression to: $V{PAGE_NUMBER}
   • If the page number shows 0, use $V{PAGE_NUMBER} + 1.
   • If the page number always shows 1 of Y, set Expression to $V{PAGE_NUMBER} instead of the initial value expression, and leave the initial value expression empty.
5. Set Reset type to: Page

These settings are illustrated in the following figure:

Setting the Expression to 1 prevents its value from being null. That is, if the footer shows Page null of 4 it probably means that the Expression hasn't been set.

The variable is created.

Add Page Footer

Add a Page Footer band as follows:

1. Select the report in the outline panel
2. Check Summary With Page Header And Footer to ensure the page footer appears on the summary page.
3. Add a Page Footer band.

The footer is added.

Create Text Field

Create a text field as follows:

1. Drag and drop a single text field onto the Page Footer band.
2. Select the text field.
3. Set Expression to: msg("Page {0} of {1}", $V{V_CURRENT_PAGE_NUMBER}, $V{PAGE_NUMBER})
4. Set Evalutation Time to: Auto

These settings are illustrated in the following figure:

The single text field is created.

For a report with three pages plus a summary page, previewing the report shows:

The summary page shows:
