javascript - 扩展JS 4.2 : Checkbox model selection issue

Question

我最近从 4.1.3 切换到 4.2.1。我有一个带有复选框模型的网格。当用户选择或取消选择记录时，应用程序会根据公共(public)记录属性值选择(或取消选择)所有相关记录。这工作得很好，但是，迁移后，停止工作。当我查看 FB 时，我可以看到触发了两个事件(选择和取消选择)

var exSelectionModel = Ext.create('Ext.selection.CheckboxModel', {
checkOnly: false,

viewConfig: {
    listeners: {
        beforecellmousedown: function(view, cell, cellIdx, record, row, rowIdx, eOpts){

        }
    }
},
listeners: {

    selectionchange: function(sm, selections) {

        console.log(selections);
    },


    select: function( sm, record, index, eOpts ){               

        var blockId = record.data.blockId;          

        var blockRecords = sm.getStore().queryBy(function(rec){
            return rec.data.blockId == blockId;


        var records = new Array();  
        Ext.each(blockRecords.items, function(bRec){                
            records.push(bRec);
        });

        sm.select(records,true,true);


    },
    deselect: function( sm, record, index, eOpts ){
        var blockId = record.data.blockId;


        var blockRecords = sm.getStore().queryBy(function(rec){
            return rec.data.blockId == blockId;
        });

        var records = new Array();  
        Ext.each(blockRecords.items, function(bRec){  
            records.push(bRec);
        });

        sm.deselect(records,true,true);
    }
}

});

Ext JS 4.2.1 与 4.1.3 相比有什么变化

Answer 1

看来我找到了答案。我添加了以下属性

    checkOnly: true,
    allowDeselect: false,
    ignoreRightMouseSelection: true,

4.2.1 中发生了一些变化或某个地方出现了问题
