ExtJS4

我正在尝试将树节点移动到网格面板。我希望将其关联数据插入此处。但是每当我移动树节点时，它都会在该位置创建一个空行。我将树创建为：

    var treeData = {
        text: 'Business Processes',
        children:[
            {text: 'Process7', lob: 'Lob7', leaf:true},
            {text: 'Process8', lob: 'Lob8', leaf:true},
            {text: 'Process9', lob: 'Lob9', leaf:true},
            {text: 'Process10', lob: 'Lob10', leaf:true},
            {text: 'Process11', lob: 'Lob11', leaf:true},
            {text: 'Process12', lob: 'Lob12', leaf:true}
        ]
    };
    bpTreeStore = Ext.create('Ext.data.TreeStore',{});
    bpTreeStore.setRootNode(treeData);

    new Ext.TreePanel({
        id:'businessProcessTree',
        store : bpTreeStore,
        viewConfig: {
            plugins:{
                ptype: 'treeviewdragdrop',
                dropGroup: 'dragGroup',
                dragGroup: 'dragGroup',
                dragText: 'Place the node to grid'
              }
        }
    });

和网格一样

Ext.define('BusinessProcessStoreModel',{
extend:'Ext.data.Model',
fields: [
{ name:'businessProcessName', type:'string' },
{ name:'businessProcessLob', type:'string' }
]
});
bpMappingStore = Ext.create('Ext.data.ArrayStore', {
        model:'BusinessProcessStoreModel',
        data:[
            ['Process1', 'Lob1'],
            ['Process2', 'Lob2'],
            ['Process3', 'Lob3']
        ]
    });
var bpMappingGrid = Ext.create('Ext.grid.Panel',{
        id:'bpGridPanel',
        region:'center',
        frame:true,
        layout:'fit',
        height:300,
        columns:[
        { header:'Process Name', dataIndex:'businessProcessName' },
        { header:'Process Lob', dataIndex:'businessProcessLob' }
        ],
        store:bpMappingStore,
        viewConfig: {
            plugins:{
                ptype: 'gridviewdragdrop',
                dropGroup: 'dragGroup',
                dragGroup: 'dragGroup',
                dragText: 'Place the node to grid'
              },
            listeners: {
                drop: function(node, data, overModel, dropPosition)
                {
                    var position = (dropPosition=='after'?overModel.index + 1: overModel.index -1);
                    Ext.getCmp('bpGridPanel').store.insert(position, [[data.records[0].data.text, 'LOB']]);
 //data.records[0].data.lob is undefined don't know why

                }
            }
        }
    });

请告诉我如何引用要插入到网格面板的两列中的树节点的“文本”和“lob”。

我解决了这个问题。确保被拖动的 Treenode 必须包含网格正在使用的模型中的属性。

这里，treedata 可以定义为

var treeData = {
        text: 'Business Processes',
        children:[
            {text: 'Process7', businessProcessName: 'Process7', businessProcessLob: 'Lob7', leaf:true},
            {text: 'Process8', businessProcessName: 'Process8', businessProcessLob: 'Lob8', leaf:true},
            {text: 'Process9', businessProcessName: 'Process9', businessProcessLob: 'Lob9', leaf:true},
            {text: 'Process10',businessProcessName: 'Process10', businessProcessLob: 'Lob10', leaf:true},
            {text: 'Process11', businessProcessName: 'Process11', businessProcessLob: 'Lob11', leaf:true},
            {text: 'Process12', businessProcessName: 'Process12', businessProcessLob: 'Lob12', leaf:true}
        ]
    };
    this.bpTreeStore = Ext.create('Ext.data.TreeStore',{root: this.treeData});

但是当我们将这个 treedata 对象分配给 treestore 时。它删除了新属性（businessProcessName 和 businessProcessLob）。

所以要添加它们，可以运行一个循环。

for(var index in treeData.children)
{
    this.bpTreeStore.tree.root.childNodes[index].data.businessProcessName = treeData.children[index].businessProcessName;
    this.bpTreeStore.tree.root.childNodes[index].data.businessProcessLob = treeData.children[index].businessProcessLob;
}

在此之后，拖动工作正常:)
