对于数据值loadComplete jqGrid，返回false

已编辑JS:

$.extend($.jgrid.defaults, 
    {
        mtype: "POST",

        rowNum: 10,

        editurl: 'addTasks.php',
        pager: $('#assignNav'),
        caption: "Assign Tasks"
    }).navGrid('#assignNav',{edit:true,add:true,del:true},{},{},{},{multipleSearch: false, multipleGroup: false});
    $(window).bind('resize', function() {
        $("#assign").setGridWidth($(window).width()-"185");
        $("#assign").setGridHeight($(window).height()-"310");
    }).trigger('resize');
        });
    setInterval(
        function(){
            $('#assign').setGridParam({datatype: 'xml'}).trigger('reloadGrid',[{current:true}]);
        },60000);

    </script>

它返回的一切都正确

loadComplete : function()
                    {
                        var data = $grid.getCol('Details', true);
                    },

这将返回我在带有rowid的Details单元格中的内容。这解决了我遇到的问题，但我仍然想知道为什么另一个函数返回false

您应该包含使用jqGrid的完整JavaScript代码，并包含testdata（JSON或XML），以便重现您描述的问题。@Oleg更新了文章，我真正想做的是根据单元格中的内容更改行颜色，但由于此错误，我无法通过此点。

loadComplete : function()
                        {

                            var data = $grid.getCol('Details');
                            alert(data);
                        },

loadComplete : function()
                    {
                        var data = $grid.getCol('Details', true);
                    },
