extjs组合框中的多选

Question

我试图在 Extjs 的组合框中进行多选，在我选择 Items 后，tpl 索引被渲染，想要渲染离开单元格时选择的显示字段的值，我怎样才能实现这个。

这是代码

function run() {

    var myStore=Ext.create('Ext.data.Store', {
        storeId: 'simpsonsStore',
        fields: ['busname', 'time', 'typebus',],
        pageSize:2,
        proxy: {
           type: 'memory',
          enablePaging: true
    },
        data: [{
            busname: 'ABCD',
            time: '15:30:00',
            typebus: 'AC Volvo',

        }, {
            busname: 'aaa',
            time: '13:30:00',
            typebus: 'Seater',

        },{
            busname: 'AAAA',
            time: '18:30:00',
            typebus: 'Sleeper',

        },{
            busname: 'ABCD',
            time: '19:30:00',
            typebus: 'AC Volvo',

        },]
    });

    Ext.create('Ext.grid.Panel', {

我对您的原始源代码进行了一些修改。你可能喜欢或不喜欢。但是在这段代码中，你得到了你所要求的。我不确定这是否正是您想要的。

Ext.application({
    name: 'Fiddle',
