这是我正常时的右键菜单（实际上也就一个copy的子项），多次点击的时候出现一些问题

看，竟然凭空多出一个一模一样的子项，也可以用。我后来再点击右键菜单出来后，alert它的子项数量，alert出来的是1,可以视图上看有三个，有四个。。。

我搞不定,代码如下：
[code="java"]
adaptergrid.on('rowcontextmenu', rightClickFn);

var rightClick = null;
function rightClickFn(grid,rowIndex,e){
e.preventDefault();
if(Ext.getCmp('rMenu1')){
rightClick.items.remove(Ext.getCmp('rMenu1'));
}

rightClick = new Ext.menu.Menu({
    id:'rightClickCont',
    items: [
        {
            id: 'rMenu1',
            scope:this,
            text: 'copy',
            handler:function(){copy(grid,rowIndex,e);}
        }
    ]
});
rightClick.showAt(e.getXY());
alert(rightClick.items.length);

}

function copy(grid,rowIndex,e){
var record = grid.getStore().getAt(rowIndex);
var adapter = record.data.adapter;
var server = record.data.server;
var impaction = record.data.impaction;
var status = record.data.status;
var checkedTime = record.data.checkedTime;
var str = "Adapter : " + adapter + "" +
"Server : " + server + "" +
"Status : " + status + "" +
"Impaction : " + impaction + "" +
"checkedTime : "+checkedTime;
window.clipboardData.setData('text',str);
for(var i=0;i<rightClick.items.length;i++){
//rightClick.remove(rightClick.items)
alert(rightClick.items.length);
rightClick.items.remove(Ext.getCmp('rMenu1'));
alert(rightClick.items.length);
}
}
[/code]

Answer 1

吧Menu id 和子项 id都去了。
