jqGrid 右键菜单contextmenu简单实现

时间：2019-01-04 23:57:52

鼠标右键单击表格弹出快捷菜单可以查看、编辑、新增、删除行记录，这是很多项目的常见操作，jqGrid也可以实现类似功能，本案例依赖：bootstrap-contextmenu，该项目比较老了作者已经不维护，作者推荐/swisnl/jQuery-contextMenu。由于bootstrap-contextmenu依赖js、css资源更少，使用方便，因此本例仍然使用bootstrap-contextmenu实现快捷菜单弹出。

1、案例截图

点击“获取当前行”，浏览器控制台输出如下：

当前操作：获取当前行表格行数据： Object { goods_no: "2", goods_name: "零件名称501", car_type_name: "车型501", package_name: "包装器具501", unit: "箱", snp: "0.89", box_count: "51", total_count: "51", goods_count: "51", out_count: "51", … }

2、案例代码

3、代码说明

1）先定义弹出菜单DOM，务必有class=“dropdown-menu”

<div id="context-menu"><ul class="dropdown-menu" role="menu" style="min-width: 115px;"><li><a href="javascript:;" tabindex="-1" menuitem=1>获取当前行</a></li><li class="divider" style="margin: 5px 0"></li><li><a href="javascript:;" tabindex="-1" menuitem=3>删除当前行</a></li></ul></div>

2）表格构建完后，初始化快捷菜单

$grid.contextmenu({target:'#context-menu', before: function(e,context) {$grid.data("contextmenu-rowId", $(e.target).closest('tr').attr('id'));// execute code before context menu if shown},onItem: function(context,e) {// execute on menu item selectionconsole.log("当前操作：", $(e.target).text());console.log("表格行数据：", $grid.jqGrid('getRowData', $grid.data('contextmenu-rowId')));}})
