extjs 右鍵菜單

js:
//右鍵菜單
grid.addListener('rowcontextmenu', rightClickFn);//右鍵菜單代碼關鍵區段
var rightClick = new Ext.menu.Menu({
    id:'rightClickCont',
    items: [
        {
            //id: 'rMenu1',
            //handler: rMenu1Fn,
            text: '右鍵菜單1'
        },
        {
            //id: 'rMenu2',
            //handler: rMenu2Fn,
            text: '右鍵菜單2'
        }
    ]
});
//右鍵菜單代碼關鍵區段
function rightClickFn(grid,rowindex,e){
    e.preventDefault();
    rightClick.showAt(e.getXY());
}
02、單擊清單項目實現
grid.addListener('rowclick', rowclickFn);
function rowclickFn(grid,rowindex,e){
    alert('單擊 '+ rowindex);
}
03、雙擊清單項目實現
grid.addListener('rowdblclick', rowdblclickFn);
function rowdblclickFn(grid,rowindex,e){
    alert('雙擊 '+ rowindex);

}
