仅对几行禁用行选择-Primefaces [英] Disable row selection for a few rows only - Primefaces

问题描述

我想知道是否有一种方法可以基于bean属性对Primefaces中给定的一组行禁用基于无线电的行选择.

I would like to know if there is a way of disabling the radio-based row selection for a given set of rows in Primefaces, based on a bean property.

示例:

<p:dataTable var="foo" value="#{bean.foos}" selection="#{bean.selectedFoo}">`
    <p:column selectionMode="single" />
    <p:column>
        <h:outputText value="#{foo.bar}" />
    </p:column>
<p:dataTable>

在这种情况下，想象一下我想通过禁用行来禁用foo.bar == 1,5,10所在的行，我的意思是禁用与该行关联的单选按钮.

In this case, imagine I would like to disable the rows where foo.bar == 1,5,10, by disabling the rows I mean disable the radio button associated with the row.

我想不出一种方法来实现...任何想法?甚至css + javascript hack解决方案也是可以接受的.

I couldn't figure out a way of accomplish that... any ideas? Even a css + javascript hack solution would be acceptable.

推荐答案

从4.0版本开始，Primefaces数据表带有disabledSelection属性.

Since 4.0 version, Primefaces datatable comes with a disabledSelection property.

<p:dataTable var="foo" value="#{bean.foos}" selection="#{bean.selectedFoo}" disabledSelection="#{foo.bar == 1}">
    <p:column selectionMode="single" />
    <p:column>
        <h:outputText value="#{foo.bar}" />
    </p:column>
<p:dataTable>

然后，当foo.bar == 1为true时，复选框将被禁用.

Then, when foo.bar == 1 is true, checkbox will be disabled.
