如何在一個jqgrid列中添加兩種格式？

Question

在我的數據庫我有一列兩個選項：

1. /uploads/1369839038.zip
2. NULL

現在我已在「電子郵件」一欄中格式化，以便它顯示爲一個鏈接，

formatter:function(cellvalue, options, rowObject){ 
       return '<a href="' + cellvalue + '"target="_blank">FILES </a> ' 
      } } 

但我想讓它顯示空白，如果它有「空」這樣JQGRID show blank instead of Null或顯示爲像我的鏈接格式化已經有。我想在一個格式化程序中將這兩個「附件」列組合起來，以便根據數據顯示鏈接或空白。請非常感謝一些幫助。

我的jqGrid

$(function(){ 
     $("#list").jqGrid({ 
     url:'request.php', 
     editurl: "jqGridCrud.php", 
     datatype: 'xml',

    colModel :[

    delOptions: { 
     url: 'delete-perm.php', 
     afterShowForm: function ($form) { 
    $("#dData", $form.parent()).click(); 
}, 
     msg: "Remove Selected Project?", 
     bSubmit: "Remove", 
     bCancel: "Cancel" 
    } 
}}, 
    ], 
    pager: '#pager', 

    rowNum:30, 
    rowList:[30,40,80], 
    sortname: 'ddate', 
    sortorder: 'asc', 
    viewrecords: true, 
    gridview: true,

    ondblClickRow: function(rowid) { 

    $(this).jqGrid('editGridRow', rowid, 
         {width:550,Height:550,recreateForm:true,closeAfterEdit:true, 
         closeOnEscape:true,reloadAfterSubmit:true, modal:true,mtype:'post',top:350,left: 30});} 


      }); 

jQuery.extend(jQuery.jgrid.nav, { 
     deltitle: '', 
     delcaption: 'Project Complete' 


    },{delicon: "ui-icon-circle-check",deltext: "Project Complete"}); 

    $("#list").jqGrid("navGrid", "#pager", { add: false, search: false, refresh:false,edit:false }).navButtonAdd('#pager',{ 


           caption:"Export to Excel", 
           buttonicon:"ui-icon-save", 
           onClickButton: function() { 
     jQuery("#list").jqGrid('excelExport', { url: 'ExportExcel.php' }); 
}, 
           position:"last" 
          }); 
    // setup grid print capability. Add print button to navigation bar and bind to click. 
    setPrintGrid('list','pager','Current Assignments'); 

});

我不知道我理解正確，你的問題，但爲什麼不嘗試使用下面的自定義格式：

function (cellvalue, options, rowObject) { 
    if (cellvalue === undefined || cellvalue === null || cellvalue === 'NULL') { 
     return ' '; // or just "" 
    } 
    return '<a href="' + cellvalue + '"target="_blank">FILES </a>'; 
}
