jqGrid在第一次加载时排序

Question

我的网格有以下代码(我在与数据源相同的目录中使用XML文件).

var handsetGrid = $("#products").jqGrid({
    url: 'catalog.xml',
    datatype: "xml",
    colNames:["SKU", "Name", "Brand", "Description", "Metadescription"],
    colModel:[
        {name:"sku",  key: true, index:"sku", width:100, xmlmap:"sku", align:"right", sortable:true},
        {name:"Name", index:"Name", width:300, sortable:true, xmlmap:">name>en"},
        {name:"Brand", index:"Brand", width:100, sortable:true, xmlmap:"brand"},
        {name:"description", index:"description", width:400, classes:"desc1", xmlmap:"description1>en", formatter:descFormatter},
        {name:"metadescriptionEn", index:"metadescriptionEn", width:400, classes:"desc1", xmlmap:"metadescription>en", formatter:descFormatter}
    ],
    width: 1300,
    height:480,
    shrinkToFit:false,
    rownumbers: true,
    scroll: true,
    rowNum:22,
    ignoreCase: true,
    viewrecords: true,
    sortname: "Name",
    sortorder: "asc",
    sortable: true,
    loadonce: true,
    pager: "#pager",
    caption: "Handsets",                    
    xmlReader: {
        root: "products",
        row: "product",
        repeatitems: false,
        id: "sku"               
    },
    loadComplete: function(data) {
        // test whether we have initial loadind and the "data" has XML type
        if (data.nodeType) {
            myXMLdata = data; // save original XML data                         
        }
    },
    subGrid: true,
    subGridRowExpanded: function(subgrid_id, row_id) {
        var subgrid_table_id;
        subgrid_table_id = subgrid_id + "_t";
        jQuery("#" + subgrid_id).html("<table id='" + subgrid_table_id + "' class='scroll'></table>");
        jQuery("#" + subgrid_table_id).jqGrid( {
            datatype:'xmlstring',
            datastr: myXMLdata,
            colNames: [ 'Id', 'Name', 'Duration', 'Price'],
            colModel: [
                {name:"ppid",index:"ppid",width:80, xmlmap:">id"},
                {name:"ppname",index:"ppname",width:150, xmlmap:">name>en"},
                {name:"ppduration",index:"ppduration",width:85, xmlmap:">priceperduration>duration>en", formatter: durationFormatter},
                {name:"ppprice",index:"ppprice",width:80, xmlmap:">priceperduration>price", formatter: priceFormatter}
            ],
            gridview: true,
            xmlReader: {
                root: "products>product:has('sku:contains('"+row_id+"')')>priceplansavailable",
                row: "priceplan",
                repeatitems: false
            }                           
        });
    }       

}); 

$("#handsets").jqGrid('navGrid','#pager',{edit:false,add:false,del:false,search:false,refresh:false});
$("#handsets").jqGrid('navButtonAdd',"#pager",{caption:"Search Bar", title:"Toggle Search Toolbar", buttonicon :'ui-icon-pin-s',
    onClickButton:function(){
        handsetGrid[0].toggleToolbar();
    }
});

$("#handsets").jqGrid('navButtonAdd',"#pager",{caption:"Clear", title:"Clear Search", buttonicon :'ui-icon-refresh',
    onClickButton:function(){
        handsetGrid[0].clearToolbar();
    }
});

$("#handsets").jqGrid('filterToolbar', {defaultSearch:'cn'});

我的问题是当我加载网格时,我希望它已经为列排序:名称.我期望使用这三个参数:

• sortname:"名称",
• sortorder:"asc",
• sortable:是的,

单击列后它正常工作,只是第一个排序不起作用(加载页面后).

Answer 1

如果使用"xml"或"json"之类的远程数据类型,则服务器负责提供已排序的数据.

如果你不能这样做,你可以触发reloadGrid内部loadComplete,但你应该使用setTimeoutJavaScript方法来完成第一个加载过程.

要没有递归,你应该放在块的"reloadGrid"内部.if (data.nodeType)loadComplete

更新: 免费jqGrid有选项forceClientSorting: true,解决了这个问题.该选项允许在显示第一页之前强制对数据进行排序和过滤(如果postData.filters设置了可选项).
