下列程式碼為easyUI查詢列表下的排序（查詢後臺程式碼）

/*前臺程式碼*/
$("#searchList").datagrid({
    fit:true,
    singleSelect:true,
    columns:[
    //sortable:標示排序，sortName:標示要排序的列，sortOrder:標示正序OR倒序
    {field:'time',title:'時間',sortable:true,sortName:'time',sortOrder:'asc'},
    {field:'sort',title:'順序',sortable:true,sortName:'sort'
 
,sortOrder:'asc'}
    ]
});
/*後臺程式碼*/
