Question

并且有变化的反应

<xforms:bind nodeset="instance('request')/SOAP-ENV:Body/request">
    <xforms:bind nodeset="request">
    <xforms:bind nodeset="fromDate" type="xforms:date" id="bind_fromDate" />
    <xforms:bind nodeset="toDate" type="xforms:date" id="bind_toDate" />
    <xforms:bind nodeset="hoursperweek" type="xforms:int" id="bind_hoursperweek" />
</xforms:bind>

还有按钮变量

<xforms:instance id="buttons">
    <buttons>
        <submitbutton />
    </buttons>
</xforms:instance>

如果所有输入都已填满，我会显示按钮

<xforms:bind nodeset="instance('buttons')">
    <xforms:bind id="bind_savebutton" nodeset="submitbutton" relevant ="
        instance('request')/SOAP-ENV:Body/request/fromDate != '' and
        instance('request')/SOAP-ENV:Body/request/toDate != ''   and
        instance('request')/SOAP-ENV:Body/request/hoursperweek != '' " />

在身体标记

中有一个输入形式

<xforms:group ref="instance('request')">
    <xforms:input ref="fromDate" bind="bind_fromDate">
        <xforms:label>Start date</xforms:label>
    </xforms:input>
    <xforms:input ref="toDate" bind="bind_toDate">
        <xforms:label>End date</xforms:label>
    </xforms:input>
    <xforms:input ref="hoursperweek" bind="bind_hoursperweek">
        <xforms:label>Hrs.</xforms:label>
    </xforms:input>
    <xforms:trigger bind="bind_savebutton">
        <xforms:label>Save</xforms:label>
    </xforms:trigger>
</xforms:group>

但如果用相关表达式检查，如果日期是“WronDate”而不是“2013-12-14”？如何看待hoursperweek是“非数字字符串”或“23.3”而不是正整数，例如“40”？并且可以检查开始日期是否早于结束日期？并且还在更改事件中绑定而不是“鼠标移出”事件？

谢谢

以下是relevant表达式的示例：

有效日期：relevant="string() castable as xs:date"
有效的十进制数：relevant="string() castable as xs:decimal"
特定十进制数：relevant=". = 23.3"
比较日期：relevant="$start-date le $end-date"（名为start-date和end-date的控件）

Orbeon xforms使用相关属性检查有效输入
