如何在p:dataGrid中制作自动分页器 [英] how to make automatic paginator in p:dataGrid

问题描述

我想使我的<p:dataGrid>分页自动进行.无需使用下一步按钮，只需几秒钟即可移至下一页.

I would like to make my <p:dataGrid> pagination automatic. Without using the next button, move to the next page in few seconds.

<p:dataGrid id="cars" var="of" value="#{infoBaseOfVals.listinfoBaseOf}"
    columns="2" rows="4" layout="grid" paginator="true" cellpadding="10" 
    cellspacing="20px" scrolling="false" responsive="true" type="unordered" itemType="none"  
    paginatorTemplate="Nombre OFs : #infoBaseOfVals.listinfoBaseOf.size()} OFs {CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
    rowsPerPageTemplate="2,4,8,16,24,32,40,48,56,64,72,80">

我该如何实现?

推荐答案

对于PrimeFaces的最新版本(至少为6.0，但也许还有之前的版本)，您可以使用一些JavaScript来实现.将widgetVar属性设置为您的dataGrid并添加如下内容:

For recent versions of PrimeFaces (at least 6.0, but maybe also some before) You can achieve that with a little javascript. Set the widgetVar attribute to your dataGrid and add something like this:

var myVar = setInterval(myTimer, 5000);

myDataGridPaginator = PF('myDatagridWidgetVar').getPaginator();

function myTimer() {
  myDataGridPaginator().setPage(myDataGridPaginator.cfg.page + 1);
}

对于较旧的PrimeFaces版本(如果无法使用)，请参见其他答案
