Question

ExtGrid中怎么定义rowdbclick?

Answer 1

写错了.刚刚看了下 api 应该叫做 'rowdblclick'事件

[code="js"]
Ext.onReady(function(){

var myData = [
    ['3m Co',71.72,0.02,0.03,'9/1 12:00am'],
    ['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00am'],
    ['United Technologies Corporation',63.26,0.55,0.88,'9/1 12:00am'],
    ['Verizon Communications',35.57,0.39,1.11,'9/1 12:00am'],
    ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'9/1 12:00am']
];

// example of custom renderer function
function change(val){
    if(val > 0){
        return '<span style="color:green;">' + val + '</span>';
    }else if(val < 0){
        return '<span style="color:red;">' + val + '</span>';
    }
    return val;
}

// example of custom renderer function
function pctChange(val){
    if(val > 0){
        return '<span style="color:green;">' + val + '%</span>';
    }else if(val < 0){
        return '<span style="color:red;">' + val + '%</span>';
    }
    return val;
}

// create the data store
var store = new Ext.data.SimpleStore({
    fields: [
       {name: 'company'},
       {name: 'price', type: 'float'},
       {name: 'change', type: 'float'},
       {name: 'pctChange', type: 'float'},
       {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
    ]
});
store.loadData(myData);

// create the Grid
var grid = new Ext.grid.GridPanel({
    store: store,
    columns: [
        {id:'company',header: "Company", width: 160, sortable: true, dataIndex: 'company'},
        {header: "Price", width: 75, sortable: true, renderer: 'usMoney', dataIndex: 'price'},
        {header: "Change", width: 75, sortable: true, renderer: change, dataIndex: 'change'},
        {header: "% Change", width: 75, sortable: true, renderer: pctChange, dataIndex: 'pctChange'},
        {header: "Last Updated", width: 85, sortable: true, renderer: Ext.util.Format.dateRenderer('m/d/Y'), dataIndex: 'lastChange'}
    ],
    stripeRows: true,
    autoExpandColumn: 'company',
    height:350,
    width:500,
    listeners : {
        'rowdblclick':function(grid, rowIndex,e){
            alert("你双击了第" + rowIndex + 1 + "行!");
        }
    },
    title:'Array Grid'
});

grid.render(document.body);

});
