仅在 p:dataTable 中禁用几行的行选择 [英] Disable row selection for a few rows only in a p:dataTable

问题描述

我想知道是否有一种方法可以根据 bean 属性为 Primefaces 中的给定行集禁用基于单选的行选择.

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，假设我想禁用 foo.bar == 1,5,10 的行，通过禁用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.

我想不出实现这一目标的方法……有什么想法吗?即使是 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 为真时，复选框将被禁用.

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