本文介绍了如何在JasperReports中使用条件TextField?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我希望有一对TextFields取决于值。并且应根据空白区域调整y值。
I would like to have a pair of TextFields depending on a value. And the "y"-value should be adjusted depending on the empty space.
当值0时
我想隐藏TextField。
When the value is "0"
I would like to hide the TextField.
即如果参数 red $ c,我想隐藏
staticText
和 textField
$ c>等于0
并将蓝色值向上移动,在下面的jrxml代码中:
I.e. I would like to hide the staticText
and the textField
if the parameter red
is equal to "0"
and have the blue values moved up, in the jrxml-code below:
<staticText>
<reportElement x="100" y="30" width="100" height="30"/>
<text><![CDATA[Red items:]]></text>
</staticText>
<textField>
<reportElement x="200" y="30" width="40" height="30"/>
<textFieldExpression>
<![CDATA[$P{red}]]>
</textFieldExpression>
</textField>
<staticText>
<reportElement x="100" y="60" width="100" height="30"/>
<text><![CDATA[Blue items:]]></text>
</staticText>
<textField>
<reportElement x="200" y="60" width="40" height="30"/>
<textFieldExpression>
<![CDATA[$P{blue}]]>
</textFieldExpression>
</textField>
输出示例:
//if blue = 3 and red = 2 if blue = 3 and red = 0 if blue = 0 and red = 2
Red items: 2 Blue items: 3 Red items: 2
Blue items: 3
这些TextFields将放在我的报告末尾。我该怎么做?
These TextFields will be placed at the end of my report. How can I do this?
推荐答案
<reportElement ...>
<printWhenExpression><![CDATA[$P{red} == 0]]></printWhenExpression>
</reportElement>
