如何根據幾個參數的值隱藏文本字段？

我試圖隱藏我已經放置在頁面頁眉帶中的文本框。字段值由運行時傳入報表的幾個參數決定。實質上，我希望字段在參數值爲空（或其中一些爲空）時爲空或隱藏。如何根據幾個參數的值隱藏文本字段？

當我執行我的代碼時，我得到incompatable operand int and integer。我重視以下報告：

你這裏有幾個問題：

1）您設置了默認calue的參數date_start和date_end。這意味着他們永遠不會爲空。 （如果你顯式傳入參數的空值，這可能會被覆蓋，但我不確定是否誠實）。最好的辦法是不要爲這兩個參數設置默認值。

2）如果你想隱藏字段，那麼我會在字段上表達時使用打印。例如日期範圍文本框最終會看起來像：

<textField isStretchWithOverflow="true" pattern="" isBlankWhenNull="true"> 
    <reportElement uuid="9bcc0870-adaf-4bb3-bd4d-40bf120a0d1f" key="textField-1" x="0" y="54" width="802" height="42" isRemoveLineWhenBlank="true"> 
    <printWhenExpression><![CDATA[($P{date_start}!= null) && ($P{date_end}!=null)]]></printWhenExpression> 
    </reportElement> 
    <box> 
    <topPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <leftPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <bottomPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <rightPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    </box> 
    <textElement textAlignment="Left" verticalAlignment="Top" rotation="None" markup="styled"> 
    <font size="11" isBold="true"/> 
    <paragraph lineSpacing="1_1_2"/> 
    </textElement> 
    <textFieldExpression><![CDATA["Date Ticket Created From : " + new SimpleDateFormat("dd/MM/yyyy").format($P{date_start}) +"\n" + "Date Ticket Created to : " + new SimpleDateFormat("dd/MM/yyyy").format($P{date_end})]]></textFieldExpression> 
</textField>

我會做同樣的事情對你的頂部文本框也：

<textField isStretchWithOverflow="true" isBlankWhenNull="true"> 
    <reportElement uuid="37137d13-5d49-40fb-8627-0ffdfc555ef4" key="textField-2" x="0" y="20" width="802" height="35" isRemoveLineWhenBlank="true"> 
    <printWhenExpression><![CDATA[(($P{date_start}!= null) && ($P{date_end}!=null)) || ($P{lookup_year}!=-1)]]></printWhenExpression> 
    </reportElement> 
    <box> 
    <topPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <leftPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <bottomPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    <rightPen lineWidth="0.0" lineStyle="Solid" lineColor="#000000"/> 
    </box> 
    <textElement textAlignment="Center" verticalAlignment="Top" rotation="None"> 
    <font size="12" isBold="true"/> 
    <paragraph lineSpacing="Single"/> 
    </textElement> 
    <textFieldExpression><![CDATA[($P{date_start}!= null) && ($P{date_end}!=null) ? " From (" + new SimpleDateFormat("dd/MM/yyyy").format($P{date_start}) + " - " + new SimpleDateFormat("dd/MM/yyyy").format($P{date_end}) + ")" 
    : ($P{lookup_month}!= -1) && ($P{lookup_year}!=-1) && ($P{lookup_weeks}!=-1) ? "For week " + $P{lookup_weeks} +" "+ $P{lookup_month} +" "+ $P{lookup_year} 
    : ($P{lookup_month}!= -1) && ($P{lookup_year}!=-1) ? "For monthly " +$P{lookup_month} +" "+ $P{lookup_year} 
    : ($P{lookup_year}!=-1) && ($P{lookup_quarter}!=-1) ? "For Quarter " + $P{lookup_quarter} +" "+$P{lookup_year} 
    : ($P{lookup_year}!=-1) ? "For Year " + $P{lookup_year} 
    : null]]></textFieldExpression> 
</textField>

我跑這個修改報告使用空數據源，並不同的參數值，它似乎工作如何你想要的。

基本上我希望字段爲空或時隱時現的參數值是空的（或其中有些是空）

爲此，我想打印時，表達會很方便。假設param1是你的參數，你可以添加像（！$ P {param1} == null）。只有當參數有一個值時，該字段纔會顯示。 最重要的是，這在指定默認值時不起作用。因爲在指定的默認值下，參數不能爲空或爲空。
