如何在rich:dataTable中有条件地设置行的样式

特别是对于每一列:

<rich:column styleClass="#{someBean.isSomething ? 'styleIfTrue' : 'styleIfFalse' }">

但是,您始终可以尝试将所有列包装到 <rich:columnGroup> 它应该输出一个 <tr>

编辑: (回应评论):如果列中的标题面被破坏,那么您也可以将它们分离到列组中。应该有效-您甚至可能不需要标题中的列组??

<rich:dataTable>
  <f:facet name="header">
    <rich:columnGroup>
      <rich:column>Header 1</rich:column>
      <rich:column>Header 1</rich:column>
    </rich:columnGroup>
  </f:facet>
  <rich:columnGroup>
    <rich:column>Data</rich:column>
    <rich:column>Data</rich:column>
  </rich:columnGroup>
</rich:dataTable>

这是我的代码,每行上都有一个复选框,如果选中复选框,则该行将高亮显示:

<rich:dataTable value="#{manageOutstandingApprovals.approvalsResults}" var="approvals" styleClass="wp100 mtb20"  sortMode="single" id="approvalsTable"  
            enableContextMenu="false" selectionMode="none" reRender="actions" rows="10">

        <rich:column styleClass="#{approvals.rowcolor}" width="5%" sortBy="#{approvals.documentType}" sortOrder="#{manageOutstandingApprovals.documentTypeSort}">
          <f:facet name="header">
            <h:outputText value="#{messages['outstandingApprovals.documentType']}"/>
          </f:facet>
          <h:outputText  value="#{messages[approvals.documentType]}" id="col1"/>
        </rich:column>

        <rich:column styleClass="#{approvals.rowcolor}" width="5%" sortBy="#{approvals.documentID}" sortOrder="#{manageOutstandingApprovals.documentIDSort}">
          <f:facet name="header">

          </f:facet>

        <rich:column styleClass="#{approvals.rowcolor}" width="5%" sortBy="#{approvals.value}" sortOrder="#{manageOutstandingApprovals.valueSort}">
          <f:facet name="header">

          </f:facet>
          <h:outputText value="#{approvals.value}"  id="col6"/>
        </rich:column>

        <rich:column styleClass="#{approvals.rowcolor}" width="20%" sortBy="#{approvals.approverUserName}" sortOrder="#{manageOutstandingApprovals.approverSort}">
          <f:facet name="header">
            <h:outputText value="#{messages['outstandingApprovals.approver']}"/>
          </f:facet>
          <h:outputText value="#{approvals.approverUserName}" id="col7"/>
        </rich:column>

        <rich:column styleClass="#{approvals.rowcolor}" width="15%" sortBy="#{approvals.dateAssigned}" sortOrder="#{manageOutstandingApprovals.assignedSort}">
          <f:facet name="header">
            <h:outputText value="#{messages['outstandingApprovals.assigned']}"/>
          </f:facet>
          <h:outputText value="#{approvals.dateAssigned}"  id="col8"/>
        </rich:column>

        <rich:column styleClass="#{approvals.rowcolor}" width="5%" sortBy="#{approvals.dateOutstanding}"  sortOrder="#{manageOutstandingApprovals.numOutstandingSort}">
          <f:facet name="header">
            <h:outputText value="#{messages['outstandingApprovals.daysOutstanding']}"/>
          </f:facet>
          <h:outputText value="#{approvals.dateOutstanding}"  id="col9"/>
        </rich:column>

        <rich:column styleClass="#{approvals.rowcolor}">

            <a:support event="onclick" ajaxSingle="true" reRender="approvalsTable" /> 
          </h:selectBooleanCheckbox>
        </rich:column>
      </rich:dataTable>

public String getRowcolor() {
    if (selected) // selected is a variable whose value is from the checkBox  
        return "row-highlight-color"; // css id
    else
        return "row-white-color"; // css id
    }

使用 划船班

这里是一个示例,其中我的值是布尔值。(rowkey是每行的索引,您必须在rich:datatable:

rowKeyVar=“rowkey”

“订单表偶数行”:“订单表奇数行”):“已找到”}

CSS:

.found
{
background-color: #FACC2E;
}   
.order-table-even-row
{
background-color: #FCFFFE;
}

.order-table-odd-row
{
background-color: #ECF3FE;
}

您可以使用dataTables columnClasses和rowClasses属性。

我已经用Javascript做了一个混合解决方案。

<rich:column styleClass="expired" rendered="#{documento.expired}">
<f:facet name="header">
Da evadere entro
</f:facet>                  
<h:outputText value="#{documento.timeAgoInWords}" />
</rich:column>

然后是Javascript(原型包含在Richfaces中)

<script type="text/javascript">   
  function colorize() {    
    $$('td.expired').each(function(el) {
      el.up().addClassName('expired');      
    });
  }

  Event.observe(window, 'load', function() {
    colorize();
  });
</script>

这将添加一个带渲染的条件css类:

<rich:column styleClass="expired" rendered="#{documento.expired}">

使用javascript,我在每个td上循环css类过期 $$('td.expired') 并使用tr将相同的css类添加到上层节点 el.up() .

Event.observe(window, 'load', function() {});

这只是在DOM完全加载时运行函数。

当使用h:datatable时,创建一个bean方法并调用它来确定样式。也许对于rich:datatable也可以这样做?

    public String getStyleSelectedOrderRows() {
        StringBuilder sb = new StringBuilder();
        String[] oddEven = new String[]{"oddRow,", "evenRow,"};
        int i = 0;
        for (MyObject object: myObjectList) {
            sb.append(object.isSelected() ? "selected," : oddEven[i++ % 2]);
        }
        return sb.toString();
    }

在.xhtml中:

<h:dataTable rowClasses="#{bean.styleSelectedOrderRows}"
