数组数据在jqgrid中的分页问题

pagination jqgrid json jquery javascript

Brij · 技术社区 · 14 年前

我在jqgrid中面临分页问题,数组数据有18条记录,但即使我指定了p,记录也不会显示在页面中激动:真的,寻呼机:jQuery('第1页')。你能帮我实现分页而不是滚动吗。

<script type="text/javascript">
 jQuery("#list4").jqGrid({
 datatype: "clientSide",
 height: 200,
    colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'],
    colModel:[
    {name:'id',index:'id', width:60, sorttype:"int"},
    {name:'invdate',index:'invdate', width:90, sorttype:"date"},
    {name:'name',index:'name', width:100},
    {name:'amount',index:'amount', width:80, align:"right",sorttype:"float"},
    {name:'tax',index:'tax', width:80, align:"right",sorttype:"float"},
    {name:'total',index:'total', width:80,align:"right",sorttype:"float"},
    {name:'note',index:'note', width:150, sortable:false}
    ],
    multiselect: true,
 pagination:true,
  pager:jQuery('#pager1'), 
 rowNum: 10,
 rowList: [5, 10, 20, 50],
 sortname: 'id',   
 sortorder: 'asc',
 viewrecords: true,
 page: 1,
 loadonce: true,  
 totalpages: 2,   
 totalrecords:18,     
 showpage:true,   
 imgpath: "/themes/default/images",         
 caption: "Manipulating Array Data"
 });
 var mydata = [
 {id:"1",invdate:"2007-10-01",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"},
 {id:"2",invdate:"2007-10-02",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"},

你的主要问题是你应该重置 rowNum 在添加大量行之后。线路

jQuery("#list4").setGridParam({ rowNum: 10 }).trigger("reloadGrid");

jQuery("#list4").jqGrid('navGrid','#pager1',{edit:false,add:false,del:false});

直接在jqGrid的定义之后。这样,您不仅可以进行数据分页,还可以进行数据过滤(搜索)和刷新(重置过滤器)。

还有一些小评论:

在 mydata 应删除“,”在“]”之前的数组。
在for循环中,您应该使用 i<mydata.length 而不是 i<=mydata.length .
您应该从jqGrid的定义中删除以下不存在的参数(如 pagination loadonce: true ): , page , loadonce , totalpages , totalrecords showpage , imgpath .

data: myData 参数,或从 addRowData 中的方法 http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#array_data

添加jQuery(“#list4”).setGridParam({rowNum:10}).trigger(“reloadGrid”);

但如果 格式化程序 属性设置为rowObject值未定义的位置。(如果使用)

例如

function getFormattedFileName(cellvalue, options, rowObject) {

        if(!rowObject.fileName) {// this is due to ...trigger("reloadGrid");
            return cellvalue; // the value is already formatted, let's just return it
        }
 return rowObject.fileName.trim();
}
