Ext之grid右键菜单

 Ext.ns('Ext.ux.grid');
 Ext.ux.grid.RightMenu = function(options) {
     var currRecord = false;
     var currRowIndex = false;
     var currGrid = false;
     var menuItems = Ext.each(options.items, function() {
                 var item = this;
                 this.handler = function() {
                     item.recHandler
                             && item.recHandler(currRecord, currRowIndex,
                                     currGrid);
                 };
             });
     var menu = new Ext.menu.Menu({
                 items : options.items
             });
     this.init = function(grid) {
         grid.addListener('rowcontextmenu', function(client, rowIndex, e) {
                     e.preventDefault();
                     if (rowIndex < 0) {
                         return;
                     }
                     client.getSelectionModel().selectRow(rowIndex);
                     currRowIndex = rowIndex;
                     currRecord = grid.getStore().getAt(rowIndex);
                     currGrid = grid;
                     menu.showAt(e.getXY());
                 });
     };
 };

 var rightMenu = new Ext.ux.grid.RightMenu({
             items : [{
                         text : '增加',
                         recHandler : onAdd
                     }, {
                         text : '删除',
                         recHandler : function(record, rowIndex, grid) {
                             alert(1);
                         }
                     }]
         });

只需要将上面代码作为插件使用就OK了

 selModel : new Ext.grid.RowSelectionModel({
             singleSelect : true
         }),
 plugins : [rightMenu],
