在jqgrid中未触发提交之前的功能

Question

您好，我有一个通过格式操作的 jqgrid 编辑功能。是否可以在提交之前使用该方法并执行验证。

formatoptions: {
                        keys: true, // we want use [Enter] key to save the row and [Esc] to cancel editing.
                        onEdit: function (rowid) {
                            //alert("in onEdit: rowid=" + rowid + "\nWe don't need return anything");
                        },
                        onSuccess: function (jqXHR) {
                            $('input[id*="gs_"]').val("");
                            $grid.setGridParam({ search: false, postData: { "filters": ""} ,datatype: 'json'}).trigger("reloadGrid");
                            // the function will be used as "succesfunc" parameter of editRow function
                            // (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing#editrow)
                            /*alert("in onSuccess used only for remote editing:" +
                                "\nresponseText=" + jqXHR.responseText +
                                "\n\nWe can verify the server response and return false in case of" +
                                " error response. return true confirm that the response is successful");
                            // we can verify the server response and interpret it do as an error
                            // in the case we should return false. In the case onError will be called
                            return true;*/
                        },
                        onError: function (rowid, jqXHR, textStatus) {
                            // the function will be used as "errorfunc" parameter of editRow function
                            // (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing#editrow)
                            // and saveRow function
                            // (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing#saverow)
                            /*alert("in onError used only for remote editing:" +
                                "\nresponseText=" + jqXHR.responseText +
                                "\nstatus=" + jqXHR.status +
                                "\nstatusText" + jqXHR.statusText +
                                "\n\nWe don't need return anything");*/
                        },
                        afterSave: function (rowid) {
                            //alert("in afterSave (Submit): rowid=" + rowid + "\nWe don't need return anything");
                        },
                        afterRestore: function (rowid) {
                            //alert("in afterRestore (Cancel): rowid=" + rowid + "\nWe don't need return anything");
                        },
                        delOptions: myDelOptions
                    }
    }       ],

函数永远不会被触发。我希望执行 ajax 请求以进行验证，

请提供帮助和感谢

在内联编辑中有beforeSaveRow（如果你不使用一些旧版本的jqGrid）。不能在formatter: "actions" 的formatoptions 内部设置回调，但可以改用$.jgrid.inlineEdit：

$.extend(true, $.jgrid.inlineEdit, {
    beforeSaveRow: function (options, rowid) {
        ...
        return true; // return false break submiting
    }
});
