Question

var menu1 = new Ext.menu.Menu({
    items: [{
        text: 'Open in new tab'

    }]
});
var treePanel = Ext.create('Ext.tree.Panel', {
    id: 'tree-panel',
    region: 'center',
    useArrows: true,
    singleExpand: true,
    split: false,
    height: 360,
    minSize: 150,
    rootVisible: false,
    autoScroll: true,
    store: store,
    border: false,
    columns: [{
        xtype: 'treecolumn',
        dataIndex: 'text',
        flex: 2,
        sortable: true,
        displayField: true
    }]

});
treePanel.on('contextmenu', function(event, node) {
    alert(node)
    //treePanelCurrentNode = node;
    x = event.browserEvent.clientX;
    y = event.browserEvent.clientY;
    menu1.showAt([x, y]);
}, this);

使用4.1 ext js并尝试将上下文菜单添加到此树面板但菜单不起作用。在树面板商店即将到来但我的代码

treePanel.on('contextmenu', function(event,node){};

无效不是事件

treePanel.on('click', function(event,node){};

任何与树面板上的ext js上下文菜单相关的想法？

Answer 1

树在ExtJS4中没有contextmenu事件。

您应该使用itemcontextmenu代替contextmenu：

treePanel.on('itemcontextmenu', function(view, record, item, index, event) {
    alert(record)
    //treePanelCurrentNode = record;
    menu1.showAt(event.getXY());
    event.stopEvent();
}, this);

Answer 2

当呈现数据视图时，它禁用默认的右键单击Web浏览器菜单，这在侦听器“render”事件中调用，“itemcontexmenu”事件用于检测右键单击鼠标事件，捕获鼠标光标位置并显示菜单

  listeners: {


        render: function() {
             Ext.getBody().on("contextmenu", Ext.emptyFn, null, {preventDefault: true});
        },
        itemcontextmenu : function( grid, record, item, index, event){
            x = event.browserEvent.clientX;
            y = event.browserEvent.clientY;

            menu1.showAt([x, y]);


        }
}

extjs树面板上下文菜单无法正常工作
