extjs表格搜索框代码

以下是一个简单的 extjs 表格搜索框代码示例：

Ext.create('Ext.toolbar.Toolbar', {
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: '搜索',
        labelWidth: 50,
        width: 200,
        enableKeyEvents: true,
        listeners: {
            keyup: function(field, e) {
                var value = field.getValue();
                var store = Ext.getCmp('myGrid').getStore();
                store.clearFilter();
                if (value) {
                    var regex = new RegExp(value, "i");
                    store.filterBy(function(record) {
                        return regex.test(record.get('name'));
                    });
                }
            }
        }
    }]
});

Ext.create('Ext.grid.Panel', {
    id: 'myGrid',
    renderTo: Ext.getBody(),
    store: Ext.create('Ext.data.Store', {
        fields: ['name', 'email', 'phone'],
        data: [{
            name: 'Lisa',
            email: 'lisa@simpsons.com',
            phone: '555-111-1224'
        }, {
            name: 'Bart',
            email: 'bart@simpsons.com',
            phone: '555-222-1234'
        }, {
            name: 'Homer',
            email: 'homer@simpsons.com',
            phone: '555-222-1244'
        }, {
            name: 'Marge',
            email: 'marge@simpsons.com',
            phone: '555-222-1254'
        }]
    }),
    columns: [{
        text: '姓名',
        dataIndex: 'name'
    }, {
        text: '邮箱',
        dataIndex: 'email'
    }, {
        text: '电话',
        dataIndex: 'phone'
    }]
});
