Question

我有一个包含网格的字段集，该网格有3个checkcolumns：Leader，Member和Viewer。如果用户单击Leader checkcolumn中的复选框，则应禁用Member和Viewer复选框中的相应复选框（即用户不能单击这些复选框）。如果用户单击Member或Viewer checkcolumns中的复选框，也是如此;其他复选框不应该是可点击的。任何想法如何去做？

Answer 1

RadioGroup不可行，因为应用程序需要允许用户检查多个复选框（在一个复选列中）。我已经部分解决了这个问题：现在，如果我单击Leader checkcolumn中的任何复选框，然后单击Viewer或Member checkcolumns中的复选框，Leader checkcolumn中的刻度标记将消失。唯一的问题是，当前如果用户单击“成员”或“查看者”复选列中的“任何”复选框，则“领导者”复选列中的任何选中复选框都将变为未选中状态。但是，我只想取消选中CORRESPONDING复选框（即同一行中的复选框）。以下是checkcolumns的代码，包含checkcolumns和store的网格：

    //Ext.Loader.setPath('Ext.ux', 'ext/js/ux');

    Ext.require([

我能够使用record.set解决这个问题。我的代码如下：

Ext.Loader.setConfig({enabled: true, paths:{'Ext.ux': 'ext/js/ux'}});

    Ext.require([
        'Ext.grid.*',
        'Ext.data.*',
        'Ext.ux.grid.HeaderToolTip',
        'Ext.ux.CheckColumn'
    ]);

    Ext.onReady(function () {

    Ext.tip.QuickTipManager.init();

    var teststore = Ext.create('Ext.data.ArrayStore', {
        fields: [
           {name: 'UserID', type: 'asUCString'},
           {name: 'Name', type: 'asUCString'},
           {name: 'Role', type: 'asUCString'},
           {name: 'Leader', type: 'bool'},
           {name: 'Member', type: 'bool'},
           {name: 'Viewer', type: 'bool'}
        ],
        data: [
            ['1', 'Hans Hansel', 'Customer/Freelancer', false, false, false],
            ['2', 'Doreen Duck', 'Consultant', false, false, false],
            ['3', 'Gerald Goose', 'Client', false, false, false],
            ['4', 'Frederic Fitzgerald', 'Super User IT', false, false, false],
            ['5', 'Aimee Anselm', 'Administrator', false, false, false]
        ]
    });


    var grid = Ext.create('Ext.grid.Panel', {
        id: 'setPermissionsGrid',
        title: '',
        store: teststore, //Ext.data.StoreManager.lookup('simpsonsStore'),
        plugins: ['headertooltip'],
        //selType: 'checkboxmodel',
        columns: [
            { text: 'Name',  dataIndex: 'Name', width: 120},
            { text: 'Role',  dataIndex: 'Role', width: 125},
            { text: 'Leader', dataIndex: 'Leader', xtype: 'checkcolumn', listeners: {'checkchange' : function(column, recordIndex, checked) {var record = teststore.getAt(recordIndex); record.set('Member', false); record.set('Viewer', false); }},width: 68, tooltip: '<b>Team Leader Rights:</b> '},
            { text: 'Member', dataIndex: 'Member', xtype: 'checkcolumn', listeners: {'checkchange' : function(column, recordIndex, checked) {var record = teststore.getAt(recordIndex); record.set('Leader', false); record.set('Viewer', false); }},width: 68, tooltip: '<b>Team Member Rights:</b> '},
            { text: 'Viewer', dataIndex: 'Viewer', xtype: 'checkcolumn', listeners: {'checkchange' : function(column, recordIndex, checked) {var record = teststore.getAt(recordIndex); record.set('Leader', false); record.set('Member', false); }},width: 68, tooltip: '<b>Team Viewer Rights:</b> '}

        ],
        height: 219,
        width: 450,
        renderTo: Ext.getBody()
