PrimeFaces dataTable滚动条在所需位置 [英] PrimeFaces dataTable scrollbar at desired position

问题描述

当我添加一条新记录(在默认的可见区域之外)并更新从记录0加载数据表的数据表时，我有一个包含100多个记录的可滚动数据表，而我需要在前一个位置查看数据表.

I have a scrollable dataTable with 100+ records when I add a new record (outside the default viewable area)and update the datatable the dataTable gets loaded from record 0, whereas I need datatable view at the previous position.

我的数据表代码

<p:dataTable id="DataTable" value="#{dtMB.selectDataModel}" var="test" scrollable="TRUE" scrollHeight="500" styleClass="day-column2" selectionMode="single" >
 <ui:insert name="TableInsert" >
        <ui:include src="test.xhtml" />
 </ui:insert>   
</p:dataTable>

用于更新数据表的命令按钮(在对话框中)

Command Button (inside a dialog) which updates the Datatable

<p:commandButton id="saveNew"  value="Save" type="submit" process="@parent" onsuccess="addNew.hide()"  action="#{dtMB.addNew()}"   update=":FORM:usrMsg :FORM:TABView:DataTable"/>

当前，我需要回滚到第n条记录，以查看添加的内容或进行任何更新等. primeface数据表中是否有任何选项，或者我需要为此编写一个JavaScript.

currently I need to scroll back to the n'th record to see what was added or do any updates etc. Is there any option in primeface datatable, or I need to write a javascript for the same.

document.getElementById('receptionFORM:scrollPos').value = scrollPos;
}

function autoScroll() {
var scrollPos = document.getElementById('receptionFORM:scrollPos').value;
jQuery('#receptionFORM\\:receptionTV\\:scheduleDataTable .ui-datatable-scrollable-body').animate({scrollTop:scrollPos}, scrollPos); 
}

<h:inputHidden id="scrollPos" />

在数据表行的Ajax事件中选择

onstart="saveScrollPos()"

保存记录时，在CommandButton中使用以下代码
