jqgrid - 如何在jqgrid中删除带有本地数据的行

Question

jqGrid 参数 loadonce: true 使用

选择行并按删除按钮

未设置网址

如何仅删除本地数据中的行并抑制此错误消息？
是否可以设置一些虚拟 url 或任何其他想法来允许行删除？
如果添加和编辑表单也可以用于本地数据，那就太好了。

            url: 'GetData',
            datatype: "json",
            multiselect: true,
            multiboxonly: true, 
            scrollingRows : true,
            autoencode: true,
            loadonce: true, 
            prmNames:  {id:"_rowid", oper: "_oper" }, 
            rowTotal: 999999999,
            rownumbers: true,
            rowNum: 999999999,

从 Oleg 的回答中，我理解了以下解决方案:

禁用 jqGrid 标准删除按钮

向工具栏添加新的删除按钮。

从此按钮单击事件调用提供

grid.jqGrid('delGridRow', rowid, myDelOptions);

方法。
可以选择多行。如何删除所有选定的行，此示例仅删除一个？

更改 jqGrid 以便删除、编辑、添加按钮在没有 url 的情况下工作不是更好吗？目前需要传递虚拟 url，它总是为本地数据编辑返回成功。

您可以使用 delRowData方法删除任何本地行。

您可以使用 delGridRow如果需要，可以从表单编辑中获取。我描述的方式here并用于格式化程序:'actions'(参见 here 、 here 和最初的 here )。

var grid = $("#list"),
    myDelOptions = {
        // because I use "local" data I don't want to send the changes
        // to the server so I use "processing:true" setting and delete
        // the row manually in onclickSubmit
        onclickSubmit: function(options, rowid) {
            var grid_id = $.jgrid.jqID(grid[0].id),
                grid_p = grid[0].p,
                newPage = grid_p.page;

            // reset the value of processing option which could be modified
            options.processing = true;

            // delete the row
            grid.delRowData(rowid);
            $.jgrid.hideModal("#delmod"+grid_id,
                              {gb:"#gbox_"+grid_id,
                              jqm:options.jqModal,onClose:options.onClose});

            if (grid_p.lastpage > 1) {// on the multipage grid reload the grid
                if (grid_p.reccount === 0 && newPage === grid_p.lastpage) {
                    // if after deliting there are no rows on the current page
                    // which is the last page of the grid
                    newPage--; // go to the previous page
                }
                // reload grid to make the row from the next page visable.
                grid.trigger("reloadGrid", [{page:newPage}]);
            }

            return true;
        },
        processing:true
    };

然后使用

grid.jqGrid('delGridRow', rowid, myDelOptions);

更新 : 如果是 multiselect: true myDelOptions可以修改为以下内容:

var grid = $("#list"),
    myDelOptions = {
        // because I use "local" data I don't want to send the changes
        // to the server so I use "processing:true" setting and delete
        // the row manually in onclickSubmit
        onclickSubmit: function(options) {
            var grid_id = $.jgrid.jqID(grid[0].id),
                grid_p = grid[0].p,
                newPage = grid_p.page,
                rowids = grid_p.multiselect? grid_p.selarrrow: [grid_p.selrow];

            // reset the value of processing option which could be modified
            options.processing = true;

            // delete the row
            $.each(rowids,function(){
                grid.delRowData(this);
            });
            $.jgrid.hideModal("#delmod"+grid_id,
                              {gb:"#gbox_"+grid_id,
                              jqm:options.jqModal,onClose:options.onClose});

            if (grid_p.lastpage > 1) {// on the multipage grid reload the grid
                if (grid_p.reccount === 0 && newPage === grid_p.lastpage) {
                    // if after deliting there are no rows on the current page
                    // which is the last page of the grid
                    newPage--; // go to the previous page
                }
                // reload grid to make the row from the next page visable.
                grid.trigger("reloadGrid", [{page:newPage}]);
            }

            return true;
        },
        processing:true
    };

更新 2 : 要在删除操作上使用键盘支持并将“删除”按钮设置为默认值，您可以在 delSettings 中添加附加选项

afterShowForm: function($form) {
    var form = $form.parent()[0];
    // Delete button: "#dData", Cancel button: "#eData"
    $("#dData",form).attr("tabindex","1000");
    $("#eData",form).attr("tabindex","1001");
    setTimeout(function() {
        $("#dData",form).focus(); // set the focus on "Delete" button
    },50);
}
