删除jqGrid行数据的问题-客户端-

Question

我正在使用带有本地数据的 jQuery Grid 插件。如果我删除选定的行，该行就会消失。然后，当我转到下一页并再次返回时，已删除的行也再次返回！ 如何永久删除此行或出了什么问题？ 代码如下：

jQuery(document).ready(function(){
        // jQuery main function
        $("#Dialog").dialog({autoOpen:false, show:'slide', hide:'explode', resizable:false, modal:true, buttons:{"OK":function(){ $(this).dialog("close"); }}});
        $("#DelResGrid").dialog({autoOpen:false, show:'slide', hide:'explode', resizable:false, modal:true, buttons: {
            "Abbrechen": function() {
                $(this).dialog("close");
            }, "Alles löschen!": function() {
                // Clear grid content -> execution <-
                $("#ResultGrid").clearGridData(true);
                RefreshMap();
                $(this).dialog('close');
            }
        }});
        $("#Delete").dialog({autoOpen:false, show:'slide', hide:'explode', resizable:false, modal:true, width:425, buttons: {
            "Abbrechen": function() {
                $(this).dialog("close");
            }, "Gewählte Löschen":function() {
                // Delete selected Rows
                var ID = $("#ResultGrid").getGridParam('selrow');
                if(ID == null || ID == undefined) {
                    // No address selected
                    $("#Dialog").html("<p><span class=\"ui-icon ui-icon-info\" style=\"float:left; margin:0 7px 20px 0;\"></span>Bitte eine Adresse ausw&auml;hlen!</p>");
                    $("#Dialog").dialog("option", "title", "Hinweis:");
                    $("#Dialog").dialog("open");
                } else {
                    $("#ResultGrid").delRowData(ID);
       /****************************** Here is a change ******************************/
                    $("#ResultGrid")[0].refreshIndex();
       /****************************** Here is a change ******************************/
                    $("#ResultGrid").trigger("reloadGrid");
                }
                if($("#ResultGrid").jqGrid('getGridParam','records') < 1) {
                    RefreshMap();
                }
                $(this).dialog("close");
            }, "Alles löschen": function() {
                // Clear grid content -> dialog <-
                $(this).dialog("close");
                $("#DelResGrid").dialog("open");
            }
        }});

感谢您的回答！

刷新本地索引可能是一个已知问题（请参阅jqgrid reload grid partially working）。尝试调用

$("#ResultGrid")[0].refreshIndex();

修改jqGrid数据后。你没有发布完整的代码，所以你应该自己测试这个建议。
