Custom Pager in xpages | 易学教程

问题

I am trying to create a go to page counter combined with the pager and I found this interesting article:

http://www.mydominolab.com/2010/10/repeat-control-better-navigation.html

I have it working, but would like to change the page no. in the combo box when a page no. is clicked on in the pager (pager is doing a partial refresh at the moment). I thought of the defaultValue property at first of the combo box but that didn't work. Any ideas please?

Here is some example code:

<xp:panel styleClass="bodyText" id="dataPanel">
    <xp:panel style="font-size: 11px !important;">
        <xp:panel id="pagerArea" xp:key="headerPager">
            <div style="float:left">
                Page:&#160;
                <xp:comboBox id="cmbPages">
                    <xp:selectItems>
                        <xp:this.value><![CDATA[#{javascript:var rptControl:com.ibm.xsp.component.xp.XspDataIterator = getComponent("rptProduct");
if (rptControl == null) return [];

var total = vwProduct.getAllEntries().getCount(); //rptControl.getRowCount();
var rowsperpage = rptControl.getRows();
var totalpages = Math.ceil(total/rowsperpage);

var arr=[];
for (var i=1;i<=totalpages;i++) {
arr.push(@Text(i))
}
return arr}]]></xp:this.value>
                    </xp:selectItems>
                    <xp:eventHandler
                        event="onchange" submit="true" refreshMode="partial"
                        refreshId="dataPanel">
                        <xp:this.action><![CDATA[#{javascript:var pager:com.ibm.xsp.component.xp.XspPager = getComponent("pager1_Hidden");
pager.gotoPage(parseFloat(getComponent("cmbPages").getValue()) - 1);}]]></xp:this.action>
                    </xp:eventHandler>
                </xp:comboBox>
            </div>
            <xp:pager partialRefresh="true" id="pager1"
                for="rptProduct">
                <xp:pagerControl id="pagerControl1"
                    type="FirstImage">
                </xp:pagerControl>
                <xp:pagerControl id="pagerControl8"
                    type="Separator">
                </xp:pagerControl>
                <xp:pagerControl id="pagerControl2"
                    type="PreviousImage">
                </xp:pagerControl>
                <xp:pagerControl id="pagerControl6"
                    type="Separator">
                </xp:pagerControl>
                <xp:pagerControl id="pagerControl5"

                <xp:pagerControl id="pagerControl9"
                    type="Separator">

                    type="LastImage">
                </xp:pagerControl>
            </xp:pager>
        </xp:panel>
        <xp:pager partialRefresh="true"
            id="pager1_Hidden" for="rptProduct" layout="Previous Group Next"
            style="display:none;" pageCount="1000">
        </xp:pager>
    </xp:panel>
    <div style="clear:both;"></div>
    <br />
    <xp:repeat id="rptProduct" rows="16" value="#{vwProduct}"
        var="productRow">
        <xp:panel styleClass="linkPanel" id="panel1">
            <xp:text escape="false" id="imgHTML">
                <xp:this.value><![CDATA[#{javascript:getImgURLForProduct(productRow.getDocument());}]]></xp:this.value>
            </xp:text>
            <xp:eventHandler event="onClientLoad"
                submit="true" refreshMode="norefresh"></xp:eventHandler></xp:panel>
    </xp:repeat>
    <xp:eventHandler event="onClientLoad" submit="true" refreshMode="norefresh"></xp:eventHandler>
</xp:panel>

Few people e-mailed me with the same question. Since then I have updated my article. Have you tried that yet.

http://www.mydominolab.com/2010/10/repeat-control-better-pagination.html

Basically, you have put a piece of code in the beforeRenderResponse event as explained there. Let me know if that didn't resolve the problem. I have it working in my database.

I have the following code working. It is changing pages with the combobox, in IE9 and Firefox.

<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

    <xp:this.data>
        <xp:dominoView var="vwProduct" viewName="testview"></xp:dominoView>
    </xp:this.data>


    <xp:panel styleClass="bodyText" id="dataPanel">
        <xp:panel style="font-size: 11px !important;">
            <xp:panel id="pagerArea" xp:key="headerPager">
                <div style="float:left">
                    Page:&#160;
                    <xp:comboBox id="cmbPages">

if (rptControl == null) return [];

var total = vwProduct.getAllEntries().getCount();
var rowsperpage = rptControl.getRows();
var totalpages = Math.ceil(total/rowsperpage);

var arr=[];
for (var i=1;i<=totalpages;i++) {
arr.push(@Text(i))
}
return arr}]]></xp:this.value>
                        </xp:selectItems>
                        <xp:eventHandler event="onchange" submit="true"

                </xp:text>

            </xp:panel>
        </xp:repeat>

    </xp:panel>


</xp:view>

回答3:

Found a solution by updating it on client-side, probably could be improved using jquery or dojo.

After the combo box, I added the following computed field (I have hard coded 16 for now, since I have 16 rows per page):

<xp:text escape="false" id="computedField1">
    <xp:this.value><![CDATA[#{javascript:var cmbFieldName:String = getClientId("cmbPages");
var strJS:java.lang.StringBuffer = new java.lang.StringBuffer();
var rptControl:com.ibm.xsp.component.xp.XspDataIterator = getComponent("rptProduct");

strJS.append("<script>");

strJS.append("$(function() {");

strJS.append("document.getElementById(\"" + cmbFieldName + "\").value = \"" + ((rptControl.getFirst() / 16) + 1) + "\";");

strJS.append("});");

strJS.append("</script>");

return strJS.toString();}]]></xp:this.value>
</xp:text>

And that did the trick!
