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;
						}
						currRowIndex = rowIndex;
						currRecord = grid.getStore().getAt(rowIndex);
						currGrid = grid;
						menu.showAt(e.getXY());
					});
		};
	};

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],
