primefaces4 翻页时更新分页footer，totalRecords的更新

来源：互联网发布：科赫兄弟知乎编辑：程序博客网时间：2024/04/30 12:27

datatable 分页时发现，两个浏览器，其中一个添加数据后，另外那个翻到另一页，表格的内容变了，新增的数据有显示，但是总记录数没有更新，以致总页数不会更新。

找了一天，才找到解决办法。

<p:dataTable var="recipe" value="#{recipeBean.model}"widgetVar="rtable" filterEvent="enter" rowKey="#{recipe.id}"paginator="true" rows="10" lazy="true" first="0"paginatorPosition="bottom" id="recipe_data_id"currentPageReportTemplate="(Total: {totalRecords}, Page: {currentPage}/{totalPages})"paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"rowsPerPageTemplate="5,10,15,20,30,50"selection="#{recipeBean.selectedRecipes}"><p:ajax event="page"oncomplete="rtable.getPaginator().setTotalRecords(this.args.totalRecords)" />

解决办法就是添加ajax事件。

之前是，totalRecords的值不能更新，当页数有变化时，totalPages没有更新。

dataTable的ajax 事件列表:

page - On pagination.
sort - When a column is sorted.
filter - On filtering.
rowSelect - When a row is being selected.
rowUnselect - When a row is being unselected.
rowEdit - When a row is edited.
rowEditCancel - When row edit is cancelled.
colResize - When a column is being selected.
toggleSelect - When header checkbox is toggled.
colReorder - When columns are reordered.
rowSelectRadio - Row selection with radio.
rowSelectCheckbox - Row selection with checkbox.
rowUnselectCheckbox - Row unselection with checkbox.
rowDblselect - Row selection with double click.
