我有这个带有分页的 JSF 表。

              }, 
              function () {
                $(this).css("background","");
              }

            function highlight(param) {  
            var row = jQuery(param).parent().parent().children();
                row.toggleClass('highlited');
            }        
        </script>

    </h:body>
</html>

我创建了简单的行数示例，只是为了用非常简单的 html 表来表示行数。在第二个表中分页工作，但我不知道如何实现ui:repeat到h:dataTable以实现行计数。我该如何实现呢？

使用UIData#getRowIndex().

<h:dataTable binding="#{table}" ...>
    <h:column>
        #{table.rowIndex + SessionsController.firstRow + 1}
    </h:column>
    ...
</h:dataTable>

我不确定我理解正确。你只想要编号的行？

但是，我认为这并不像您想象的那么容易。h:dataTable 实际上不支持这个。混合 h:dataTable 和 ui:repeat 似乎是完全错误的方法（如果我理解正确的话）。

你可以：

  • 使用 t:dataTable（来自 Tomahawk：http ://myfaces.apache.org/tomahawk/index.html ）。在那里您可以使用 rowIndexVar 属性，如下所示：

    <t:dataTable rowIndexVar="row" value="#{someBean.value}">  
    <h:column>  
        <h:outputText value="#{row + 1}"/>  
    </h:column>  
</t:dataTable>

  • 或者，更改您的数据模型并在其中提供索引。或者使用包装类：

    public class DataWrapper{
    private int index;
    private Object model;
    // getter and setter
    ...
}

    然后将 DataWrapper 列表传递给 JSF，而不是直接传递给您的模型。当然，您首先需要在服务层中的某处设置索引。

我希望这有帮助。如果您需要进一步的帮助，请告诉我。
