推荐答案
要创建按钮,请创建 textField
with hyperlinkType =Reference
和 hyperlinkReferenceExpression
To create a button, create a textField
with hyperlinkType="Reference"
and a hyperlinkReferenceExpression
示例
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="JddButton" pageWidth="595" pageHeight="842" whenNoDataType="AllSectionsNoDetail" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="2a88eaae-fbef-4a3d-b8bf-0b12bafc985b">
<title>
<band height="80" splitType="Stretch">
<textField hyperlinkType="Reference" hyperlinkTarget="Blank">
<reportElement mode="Opaque" x="150" y="20" width="200" height="40" forecolor="#FFFFFF" backcolor="#009900" uuid="822deecb-059b-4921-bfb7-07ee7cbde26a">
<property name="net.sf.jasperreports.export.html.class" value="btn"/>
<property name="net.sf.jasperreports.export.html.id" value="idBtn"/>
</reportElement>
<textElement textAlignment="Center" verticalAlignment="Middle">
<font size="24"/>
</textElement>
<textFieldExpression><![CDATA["VIEW"]]></textFieldExpression>
<anchorNameExpression><![CDATA["myButton"]]></anchorNameExpression>
<hyperlinkReferenceExpression><![CDATA["https://stackoverflow.com/users/5292302/petter-friberg"]]></hyperlinkReferenceExpression>
<hyperlinkTooltipExpression><![CDATA["Click to view"]]></hyperlinkTooltipExpression>
</textField>
</band>

</jasperReport>
将生成
点击它会引导你到 hyperlinkReferenceExpression $ c $的值c>,在示例中我还设置了
hyperlinkTarget =Blank
,因此它会在新页面中打开。
when clicked it will direct you to the value of the hyperlinkReferenceExpression
, in example I have also set hyperlinkTarget="Blank"
so it opens in a new page.

嘿我希望我的按钮在我越过它时改变颜色....
Hey I want my button to change color when I pass over it....
没问题,(只要导出是html,在pdf中你需要用注释做一些技巧,但我会把它留下来......)。
No problem, (as long as export is html, in pdf you need to do some tricks with annotation but I will leave this out..).
我在 textElement
上添加了一些css标签,请参阅 reportElement下的属性
I have added some css tags on the textElement
see the property under the reportElement
所以一些简单的css。
So some simple css.
<style type="text/css">
a {text-decoration: none}
td.btn:hover {
background-color: yellow !Important;
}
</style>
最后,如何将此css放入输出文件?
