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https://github.com/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", … }

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 selection
console.log("当前操作：", $(e.target).text());
console.log("表格行数据：", $grid.jqGrid('getRowData', $grid.data('contextmenu-rowId')));
}
})
注意：
before: 设置当前点击行
onItem: 处理点击的是快捷菜单哪个菜单项，可以获取当前点击行数据
