jQuery EasyUI 数据网格 - 自定义排序

如果默认的排序行为不满足您的需求,您可以自定义数据网格(datagrid)的排序行为。

最基础的,用户可以在列上定义一个排序函数,函数名是 sorter。这个函数将接受两个值,返回值将如下:

valueA > valueB => 返回 1

valueA < valueB => 返回 -1

自定义排序代码

    <table id="tt"></table>
    $('#tt').datagrid({
        title:'Custom Sort',
        iconCls:'icon-ok',
        width:520,
        height:250,
        singleSelect:true,
        remoteSort:false,
        columns:[[
            {field:'itemid',title:'Item ID',width:60,sortable:true},
            {field:'listprice',title:'List Price',width:70,align:'right',sortable:true},
            {field:'unitcost',title:'Unit Cost',width:70,align:'right',sortable:true},
            {field:'attr1',title:'Attribute',width:120,sortable:true},
            {field:'date',title:'Date',width:80,sortable:true,align:'center',
                sorter:function(a,b){
                    a = a.split('/');
                    b = b.split('/');
                    if (a[2] == b[2]){
                        if (a[0] == b[0]){
                            return (a[1]>b[1]?1:-1);
                        } else {
                            return (a[0]>b[0]?1:-1);
                        }
                    } else {
                        return (a[2]>b[2]?1:-1);
                    }
                }
            },
            {field:'status',title:'Status',width:40,align:'center'}
        ]]
    }).datagrid('loadData', data);

您可以从这段代码中看到,我们为 date 列创建了自定义的 sorter。日期的格式是 'dd/mm/yyyy',可以轻松的按年月日排序。
